Yealink T46S - RingCentral.com

Hi all

I recently purchased a Yealink T46S on Facebook Market Place. Unfortunatly its provisioned to sip.ringcentral.com and no end of emails or requests lead to any results other than just frustration.

Ive read all the posts via: https://www.reddit.com/r/VOIP/s/q1VcUrE603

Tried all the suggestions including submitting the Mac address and serial number to Yealink but the phone is still provisioned

Ant attempt to hard reset is prompted for a password, all default options result to "Incorrect Password" I found a listing of passwords which also advised admn and a number combo which all failed.

Who or how can I contact Ring Central to have the provisioning removed

Thank you

Educate me?

We're using Spectrum internet and voice for our business but our city has rolled out municipal internet at a much lower price (@ 500Mbps) so I'm looking into moving us to a VOIP solution to get us fully off Spectrum. Goal is to keep it under $100/month.

Been reading up but could use some further knowledge from the hivemind. We're a small shop and I do all our own IT with just enough knowledge to get us by haha.

Looking at RingCentral and Ooma right now. Was considering the Ubiquiti offering as I want to add their security system down the roads, but we'd really want phones with physicals buttons and they also don't have any standalone handsets.

Right now we're using our old analog phones with an ATA provided by Spectrum. We have one fixed phone for our office and 3 handsets that float around the shop. Not tied to the analog ones but we'd definitely need hardphones to replace all of them. We only have two dedicated users, one who would be a softphone, all our other phones are floaters for the shop. So would we still have to pay for a user for each handset?

We also are currently paying for 5 lines; our main local number, an 800 number, a fax line, and 2 spillover lines for heavy call days. With a VOIP setup would we still need all of those extra lines?

We really don't need most of the fancy features a lot of the services offer, but need a rock-solid reliable option. Any other things I should be aware of when looking at pricing?

Go\Trunk is really shady, DO NOT recommend.

TL;DR: Go\Trunk is a middleman and isn't a provider and charges you more than higher tier SIP Providers, while routing you to low tier providers that could cause issues with your business.

We have been using Go\Trunk as our SIP Trunk provider for a while (~2-ish years) and we were actually pretty happy with them. But every month I decided to pick up the phone and make sure calls route properly. First i call my ISP provider knowing theyre on a VoIP service so its SIP to SIP to make sure that works and it did. Then i check just going to my cellphone. My personally cellphone (AT&T) wasn't ringing. So my first immediate thought was somehow, my AT&T Spam guard app blocked it. It didn't. Nothing there from the company number. So i called another employee, he didn't get a call. He also has AT&T but doesnt use the spam app. So i called another cell phone that wasn't an iPhone that was also AT&T...didn't go through. On my end, from the desktop phone it would ring, but the calls were not going through to the person i was calling.

We run FreePBX here so i went into a shell and checked the asterix logs and...no STIR/SHAKEN headers attached to the call after it hits Go\Trunk. Which obviously means AT&T is seeing our call is illegitimate and not even letting the call go through to the destination. We get a 200 back, but its fake. I guess its what AT&T does to make malicious callers think their calls are going through, but they aren't? I guess, I don't know that one. So i tried a number I knew that was a T-Mobile line, same thing. Tried calling someone i know who has Verizon, same thing. Now this is a problem because clearly its nothing on our end, its the providers end.

So I submit a support ticket to Go\Trunk and tell them what I just found and basically....what the heck?

The first response was "While they investigate, we have temporarily routed your US outbound calls through a different provider." A "different provider"? Are you not our "provider"? So i said back "Ok, well, what have you found so far that is the problem? Can i please have a more technical answer?" They replied back "I just switched your USA calls to another carrier provider and raised a ticket for the original carrier to investigate further." So their tech support doesn't even know what happened and the fact that our business line was "routed to another provider" was them telling me - "We are not a SIP Trunk Provider, were a middleman between the customer and low tier SIP Trunk providers."

Now, this might be common knowledge to some, but this was news to us and we used them for 2+ years and never had issues until we decided to do this test. NO WHERE on their website do they say this. That they, in essence, are infact, NOT a provider, but they will ROUTE you to a provider they probably have contracts with and clearly, we were moved, unknowingly, to another provider that did not put STIR/SHAKEN headers attached to our outbound calls, which is a red flag to telecom companies, and it drops the calls and (atleast the way AT&T does this), makes our PBX think the call was routed and we get a 200 OK, but its a lie to the phone system. So, this is just a warning to those that DON'T know this because I just caught them doing that, they do not disclaim on their website anywhere they are just a reseller to other providers, in fact they say "Go trunk is a world leading SIP Trunking solution." So they arent saying they are a provider, but they are saying they are a "solution" lol. They also say "Why GoTrunk? Because we set new standards in SIP Trunking!" Well, pretty low standards there.

We have ported our number to a higher tier provider that is infact a "provider", of course I won't say who just to keep to the rules in here as best as I can and its sad to know we were actually paying alot more, to get alot less. We were naive when we implemented having a PBX at the time, we hired better networking specialists, we audit ourselves better now, we have done our research, and its a mistake we won't make again.

Our Coredial reseller business never took off. Anybody want the monthlys?

About 5 yrs ago we decided to try reselling voip. It went OK but never really took off. We have 4 companies that buy voip services from us monthly.

Given our super low volume, the new requirements for antispam registration etc. are making the past few months a net loss, and I'm sure this is only the beginning of that.

Any coredial resellers out there wanting to absorb 4 more companies? Not looking "sell" them - just need an established Coredial reseller to take them over.

VOIP for call forwarding?

Hello. I have a new business that requires an "office number", I do not want this number to be the same as my personal cell phone number. I want to post this office number online and on my website, without exposing my personal cell phone number.

I need to get a new phone number that I can display online, and whoever calls that number would directly call my personal cell phone number, without me having to post my cell number online.

It would also help if I can see texts sent to that "office number", read voicemails for calls I could not answer, or be able to leave a voicemail response to people, asking them to leave a message.

Telegram keeps blocking my voip number

I am trying to move some accounts over to a virtual line but Telegram refuses to accept the number. It gives an invalid number error because it flags the voip carrier block. I do not want to buy a physical sim card for a single login code.

Edit: Swapped to a mobile line from BEE-SMS for the telegram registration instead of fighting with the gvoice settings. It went through instantly.

Weird experience with voip.ms, outbound calls misrouted or misidentified as spam

I posted my original saga in r/voipms some time ago with few replies, wonder if this type of thing is happening elsewhere in the voip world.

I have been a customer of voip.ms for many years, like more than 10. Over that time numerous old landline numbers of family members have been ported in so they can forward to mobile, receive SMS, and use as backup. Some have been consolidated from other services e.g. Ooma.

Starting about a year ago outbound calls began behaving strangely. A normal call from voip.ms, using one of these long established numbers as CID, outbound to cell phones that all happen to be on AT&T network, would get diverted to a fake voice mail leading the caller to believe they could leave a message. Sometimes caller would get false busy, or just go to silence without progress tones. CDR status of the latter showed them as answered. The real recipient never got indication of missed call, and the fake VM recording went into a black hole. It feels like the call got routed incorrectly, or the receiving carrier identified the caller as invalid/spam - and instead of signaling busy/reorder/SIT they divert it to a black hole voice mail. I don't quite get why this is a good tactic for diverting known spammers if that were the case.

I went through numerous gyrations with voip.ms before they confessed to making some "routing optimization" that had unwanted side effects and corrected it, months after opening a trouble ticket. Problem went away for about 6 months. It returned again this month.

I'm being told they have no control over what the receiving carrier does, are originating with attestation level A, and I need to take it up with the receiving carrier. I'm not buying this story because that is what they tried to tell me last time and it turned out to be something else.

I'm starting to suspect that the pure association of my old numbers with a voip service, or maybe just with voip.ms is going to interfere with routine usage and I need to rethink what I have been doing.

Would you use this? - VOIP

I’m considering building a 100% browser-based WebRTC network diagnostic tool to help remote users troubleshoot choppy VoIP/video calls without installing native CLI tools or needing admin rights.

Standard speed tests use HTTP/TCP, which hides the UDP packet loss and jitter that ruins WebRTC traffic. This tool runs directly in the user's browser, establishes a real-time RTCPeerConnection against your own self-hosted STUN/TURN or media servers, and simulates an actual audio call stream. Using the browser's native getStats() API, it pulls second-by-second telemetry on packet loss, jitter, round-trip latency, and ICE candidate paths (ensuring they aren't falling back to TCP). At the end of a test, it generates a simple Pass/Fail gauge and a one-click "Download JSON Log" button for users to paste into a support ticket.

Is this a tool you would actually use, or does something like this already exist in your workflow? I want to make sure I’m building something enterprise teams actually need. If you'd find this helpful for your helpdesk, let me know.

Built a small VoIP/network troubleshooting toolbox

Hey everyone,

I’ve been building a small set of VoIP/network troubleshooting tools for my own use (NOC Support) and decided to publish it. At the moment, it's more so a personal/hobby project.

https://traceroo.com

The idea is basically one UI for checks I kept googling around for: DNS, SIP DNS, RTP/PCAP helpers, SIP call flow, MTR/ping/port checks, email auth, blacklist checks, fax testing, CNAM lookup, etc.

It’s still very much a work in progress, and I’m continuously tweaking the UI and tools as I use it more. Some features are rate limited, mainly fax testing and CNAM dips, because those have a real cost behind them.

There’s also a chat bot in there, though honestly I might not keep it. It’s more of an experiment right now and I’m not fully sold on whether it adds enough value versus just keeping the toolbox clean.

I’d appreciate any feedback from people who troubleshoot VoIP regularly:

  • Are the categories/tools useful?
  • Anything confusing in the UI?
  • Any tools you’d want added?
  • Anything that feels inaccurate or too noisy?
  • Any PCAP/SIP/RTP workflow that would make this more useful?

Just an FYI: if usage/costs stack up too much, some cost-based tools might get limited harder or temporarily go down. I don’t mind keeping it open for now while I gather feedback.

Thanks in advance.

UniFi Talk adds country code to outbound calls based on IP — even if it's already there. Anyone found a fix?

I've been going in circles on this for two weeks and I'm losing my mind a little.

Setup: UniFi Talk with a third-party SIP trunk. Everything works fine for incoming calls. The problem is outbound — Talk detects my country via IP and automatically adds the country code to every outbound number, no matter what. Since the numbers already have the country code in them, every call goes out double-prefixed and fails at the carrier. IVR transfers to external mobile numbers: same thing, every time.

There's no setting in the UI to change this. I've looked everywhere. The only thing I've found is that people have been reporting this since 2022 and there's been no official response.

Has anyone actually solved this? I'm starting to think SSH is the only way but I want to make sure I'm not missing something obvious before I go down that road.

Any help appreciated.

Looking for aesthetically pleasing SIP/IP phone for home PBX setup

Hey guys,

I’m planning to build a small VoIP setup in my homelab. I’ve got most things figured out already, but I’m trying to avoid putting some ugly corporate office phone in the living room..

Does anyone know good-looking SIP/IP or DECT IP phones that still work nicely with FreePBX?

Thanks!

10DLC is becoming a compliance cartel for business messaging

I know this is probably going to get buried under “spam prevention” arguments, but 10DLC has become one of the biggest, anti-compettive rorts to happen to small business communications in years.

The original pitch sounded reasonable enough: reduce spam, make messaging more trustworthy, register businesses, etc. But in practice? It feels like a giant paywall and compliance maze that mainly benefits carriers and the companies selling “compliance services.”

A few things that really bother me about it:

  • Huge barriers for small businesses and startups. If you’re a solo operator or tiny business, you need to navigate brand registration, campaign approvals, vetting scores, use-case declarations, throughput limits, random rejections, and ongoing fees just to send legitimate texts customers actually asked for.
  • Constant uncertainty. Even when you do everything “correctly,” messages still randomly get filtered or blocked. Support responses are vague, and carriers rarely explain anything properly. You can spend days troubleshooting a problem only to discover a carrier silently changed enforcement rules again.
  • Anti-competitive by design. Large enterprises can absorb compliance costs and dedicate staff to managing this nonsense. Small providers and independent VoIP operators get crushed under administration and registration overhead. It creates consolidation pressure where only the big players can realistically operate at scale.
  • It punishes legitimate use more than actual spam. Scammers adapt instantly. They rotate numbers, domains, SIMs, or move offshore. Meanwhile legitimate businesses with real opt-ins get throttled because somebody forgot a checkbox in a campaign form.
  • The fees never end. Registration fees. Vetting fees. Campaign fees. Per-message surcharges. “Trust” ecosystem fees. Third-party platform fees. Everyone gets a cut now just for the privilege of sending a text message.

And honestly, the most frustrating part is that SMS used to be one of the last relatively open communication channels. Now it feels like email all over again: gatekeepers everywhere, opaque filtering, and compliance bureaucracy piled on top of already expensive telecom services.

What bothers me most is the precedent this sets.

We’ve quietly accepted a system where a small number of carriers, aggregators, and compliance vendors effectively decide who can reliably communicate at scale, under what conditions, and at what cost.

That should concern people far beyond telecom nerds.

Because at some point we have to ask: who should hold the switch to a nation’s voice?

Right now the answer seems to be: whichever corporations can afford the compliance department.

I’m not defending spam. Nobody wants robocall-tier garbage flooding phones. But the current system feels massively over-engineered and tilted toward incumbents.

Curious whether other people in telecom/VoIP/MSP land are seeing the same thing or if I’m just becoming old and bitter.

I threw together a video and posted it here https://youtu.be/pEdcVMyJMUY

Automated IVR Testing

Hey, I'm info gathering. After operating a large contact centre and being frustrated with the release cycle (testing being the issue) I built a SaaS platform called, but as per the rules I won't advertise it.

I'd like to understand what I'm up against in the market with the likes of organisations like Cyara, Klearcom and Hammer by Empirix - specifically on the purchasing friction and scalability without the long procurement cycle.

Figured there might be a few in the community that have relevant/recent experience that wouldn't mind sharing their experience.

Looking for PCAPs and testers for a SIP PCAP analyzer tool

I use sngrep and homer so usually i save off pcaps and can't open them without transferring to another box with my toolset or having them auto delete due to some TTL. Earlier in the year I put together a chrome extension to visualize a SIP trace and it ended up being helpful for myself so I decided to rework it as its own utility site to use on all browsers.

I'm looking for any interesting PCAPs or challenging scenarios to test out the visualizer and debugger and also any feedback for people who want to give it a try. If any pcaps can be shared with me or just feedback on using the site would be great. The tool tries to highlight errors and warnings to point to reasons why there might be an issue to make things quicker to diagnose.

https://www.sipflow.dev

It's free, no signup and is client-side first so data stays locally and any sharing feature does pseudonymize PI data. There are a lot extra features like network, webrtc testing, MCP server for docs and all the tooling from the site but that's all extra. The main goal is to drop in some SIP traces and have it easy to use and highlight issues to dig into more to save time.

Recently I added more detection(RFC based) for common webrtc and T.38 issues. If anyone works with RCD for BCID, there is also an identity header decoder and validator that supports RCD.

Update: that pure Python SIP project I mentioned here is now in alpha

Some time ago I posted here about building a pure Python SIP library because I got frustrated with the current ecosystem.

I honestly expected it to stay a side experiment.

But I kept working on it, mostly because it came from a real business telephony problem I needed to solve.

Now it’s at alpha stage and stable enough for basic testing.

Current features:

- SIP signaling

- RTP audio

- stable 2-way audio

- UDP transport

- REGISTER / INVITE / BYE

pip install opensip

https://pypi.org/project/opensip/

Still alpha.

Not production-ready.

Would love honest feedback from people who’ve suffered through SIP hell 😄

[Asterisk/FreePBX/Linphone] No audio in calls, auto-disconnect after 30s, and BYE not propagating to PC — need help

I'm working on a VoIP project using Asterisk + FreePBX + Linphone. I'm fairly new to this field — I'm primarily a software developer and network engineer. I've hit a wall at a certain point and could use some help.

I've completed all the configurations. I logged into one Linphone account on my PC and another on my phone, then tried calling between them. The calls connect and a session is established, but there's no audio — I can 'talk' but neither side hears anything.

On top of that, I'm experiencing two more issues:

  1. **The call drops automatically after 30 seconds.**

  2. **When I hang up from the phone side, the call doesn't end on the PC side — it keeps going.**

Has anyone dealt with these issues before? Any help would be greatly appreciated!

🐸 Frogman: New Open Source Module for FreePBX

Mike White here, VP of Open Source at Sangoma. I wanted to drop a quick line to share something I’ve been working on for a bit.

I’ve released an open source module for FreePBX called Frogman. The idea is pretty simple: Let AI use a set of tools that will allow it to configure, diagnose, and manage FreePBX. This opens the door for quite a bit, just know that this is a traditional freepbx module and it doesn’t install AI on the box- it just makes the PBX headless. Standard methods apply and there are currently around 220 tools to choose from.

Right now it exposes three interfaces. Anything that’s created/destroyed will require human confirmation…

1: MCP for AI agent integration: The headless part- I’ve done things like build out a system just by telling Claude what to create… with my voice- I’ve even uploaded a hand drawn diagram, told the MCP client to build it and it can, easily.

2: Interactive chat console: screenshot details below- why let the ai agents have all of the fun? This is an onboard chat console that takes natural language input to perform functions within the interface with zero clicking around. It can onboard new users, diagnose extension, and much more. Just type “diagnose 101”

3: API layer for automation and external tooling: looking to build an app that can talk to freepbx? Frogman exposes all 220 tools. You can generate API keys with read/write/admin permissions directly from the chat console.

What this is…
- an experiment… The first of its kind perhaps?
- a new way to manage FreePBX

What it’s not…

- an LLM running on FreePBX
- ready for production systems - feeling brave? Proceed with caution

Still early, but I think this is a pretty interesting direction for the project. Curious to hear what you think. AMA
