r/VOIP

For anyone managing phone systems or contact center infrastructure: are AI IVR systems mature enough yet, or are they still too unpredictable for serious call flows?

I’m talking about real production requirements like routing accuracy, uptime, logging, failover, compliance review and how changes get approved. Would you trust AI IVR for enterprise inbound calls today?

Is there any possible way to factory reset the SIP-T46G? I acquired a few phones from a business that closed and they were using intermedia for their VoIP provider. The client is gone and no longer has an account with them and they don't know the admin password for the phones.

I tried resetting it to factory using these methods:

1. Holding the "OK" button but no menu or prompt comes up to factory reset it

2. Upgrading the firmware, it updated the FW but the configuration is there there. I can't login as "admin" on the phone. I tried admin/admin, admin/0000, admin/1234, admin/12345, admin/123456.

3. Contacting Yealink support, their AI says it's most likely locked to RPS. I went to the link provided, tried adding the MAC and serial # from the back of the phone but their system says it's not the correct information. I replied on the ticket that the RPS MAC unlocking system isn't taking my information from the phone. The ticket has been stuck in limbo for almost this whole week with no human response.

4. Going to the web GUI IP address but it won't load, I think it might be disabled from intermedia.

5. Using this method posted in this thread https://www.reddit.com/r/VOIP/comments/m13sxa/factory_reset_password_protected_yealink/ but the line button won't go to the network as what the person suggested

Is there any way to get rid of this config on the phone?

As a non-tech person, I was hoping if someone could help me out with this. So, basically I am an American on a work-holiday visa in Australia with an already amazing international date plan with AT&T. Now, I do need to work here, and naturally most companies require an Australian phone number. I also need an Australian phone number to open up a bank account (CommBank) and to receive SMS messages for them, as well as just casual communication with locals. I was wondering what was the most affordable way to get an Aussie phone number without buying cellular data. Like do I need a mobile SIM, as many banks dont accept VoIP numbers?

My phone number has been lost into the abyss and all my accounts and connected to it. Is there anyway to intercept my texts? I have tried reactivating to no avail. Now I’m looking for any hacks or tricks to be able to regain access to all my accounts 😭 is there a way to intercept my texts for a phone number that’s no longer active? It was a Verizon number and they say there’s no access I’m lost

Their website works, but no response to online chat requests or email support requests.

Any VOIP services that allow for sign up with web? Tried textnow and it tried to get me to scan a qr code

In the past I have asked Claude and Codex to help write Asterisk Dialplan logic (I have subscriptions for both). The quality was lack luster. When I need a few lines written they can both help out. They also help when I am stuck and I get mentle block but over all the quality seems poor. I am thinking of trying a Codex Pro account. Has anyone had any luck with Asterisk/FreeSwitch and codex?

Hello everyone, I'm fairly new to this, I've tried a couple times but It didn't go very well.

So I'm wanting to make a project with my ATA (a Linksys pap2t, not much but it's enough for what I need) and before I buy the devices I'm missing, I'd want to test the direct IP call or fax between my ATA and another one that's anywhere else, is there a way I can do that and make sure it works the way I want it to before setting everything up?

We're about to start outbound sales for our B2B AI software company, targeting founders and businesses in the US.

I've spent days comparing Twilio, Telnyx, Plivo, OpenPhone, Aircall, Dialpad, RingCentral, and a bunch of other providers, but every review seems sponsored or written by the company itself.

I'm looking for advice from people who actually make outbound calls.

My requirements are:

• Buy a US local phone number
• Make calls from India to US businesses
• Excellent call quality
• High answer rate (caller reputation matters)
• Low cost as we scale to thousands of calls per month
• APIs for future automation are a bonus

If you've used any of these providers, I'd love to know:

• Which one are you using today?
• What does it cost you each month?
• Any hidden fees or surprises?
• How reliable is the call quality?
• Which provider would you avoid?
• Has switching providers noticeably improved your answer rate?

If you had to start from scratch today with your own money, what platform would you choose and why?

Real experiences are much more valuable than affiliate blog posts. Even if you've only used one provider, I'd really appreciate hearing what worked (or didn't).

Thanks in advance!

After months of a cron job making test calls and tracking RTP packets received, the issue happened again this morning. For those who didn't read the original thread,

• Affects multiple IP phones from multiple VoIP service providers (thanks to /u/voipcanuck for helping confirm this in 2023)
• Affects multiple cable modems from multiple ISPs
• Problem happens whether modem is in bridge or router mode
• Does not affect phones behind DSL/fibre/satellite
• Rebooting the phones and router does nothing
• The only workarounds (until now) were to reboot the cable modem OR wait 6-8 hours
• After reboot, things will work properly for days to years

There was a massive storm overnight, so /u/Stubblemonster's guess about wonky voltages triggering the problem could be correct.

Six months ago we tested every characteristic of the problem packets except for DSCP tagging because the problem went away by itself before we got that far. The old adage that it's always the last thing you look for seems to be true. Outbound packets with DSCP tag EF/Expedited Forwarding (46) are dropped and do not arrive to the media gateway. Every other DSCP tag works. It's 100% repeatable.

I have been trying to diagnose this since 2020.

my nettalk duo is dying. it's something like 12 years old, and we have to keep resetting it and the connected modem weekly, which takes several tries. the things on its way out. I was considering MagicJack, but I'm not sure if it's any good. I'm in Canada, so I know the prices are slightly different, but it still seems cheap, and a good idea. I'd rather have input before commiting though.

Admittedly, my knowledge in this area is pretty limited, so if I'm not wording this correctly, please bear with me...

I would like to have a home phone for my children. Something like the Pinwheel/Tin Can looks super fun, but it would be nice to use a regular VOIP service instead so we can power an entire home phone system with it for phones in multiple rooms.

Is it possible to create a home phone system that only allows for a whitelist of numbers for calling in and out while using a VOIP?

I run a small business with a Grandlink DP752 base and DP722 handset in the office, and a Grandlink WP820 at the home office. There is one phone number/account. I have been advised to set up as parallel so both ring at the same time, however when they're both connected only the WP820 rings, is there any settings you recommend for me to fix this?

Our Twilio account was recently compromised and used for toll fraud.

The concerning part is not only that the API credentials were abused. The attacker was able to change our Voice Geographic Permissions via API from an IP geolocated to Palestine, enable Ethiopia, and then generate 1,000+ minutes of unauthorized calls to Ethiopia. This resulted in almost $500 in charges.

We had 2FA enabled and Geo Permissions / Geo Protection configured specifically to prevent this type of fraud. But apparently Voice Geo Permissions can be changed programmatically through Twilio’s API, without an additional 2FA challenge or security confirmation.

To me, this seems like a serious design issue: a fraud-prevention control should not be silently changeable via API in a way that immediately enables high-risk international calling.

Twilio even treats Geo Permission changes as security-sensitive in other products, for example, SMS Geo Permissions cannot be changed programmatically for security reasons. So why can Voice dialing permissions be changed this way?

I opened a security incident with Twilio and requested escalation/refund. Has anyone else experienced this with Twilio toll fraud or Voice Geographic Permissions being changed via API?

Timeline:

• API request from Palestine
• Voice Geographic Permissions changed
• Ethiopia enabled
• 1,000+ minutes of calls to Ethiopia
• Around $500 in fraudulent charges
• Account was mostly dormant not used in any production setup
• Account was previously used only with one 3rd party App Talkyto

This looks less like “normal credential misuse” and more like a missing security control around high-risk account settings.

This number has been harassing me and I think it’s a scam will someone text it and see what they say to them? Or call it even?
