I'm an IT guy and not much of a phone guy. Client claims they had analog fax line that was working a few days ago and when I went to check it out for them, it's give a faster busy tone- almost like back in the day when you had two phones in your house, and one had been left off the hook for a long time.

I told him call their phone guy, they say they don't have one, so I said I would look into it a bit for them.

I feel like any attempt for me to provide additional details here would just make this more confusing, so I figured I would ask people with real world experience- what is the most likely cause or solution to this? I really have no idea where to start.

Hello I currently reside in Aus and I’m looking to set up a Craigslist add but it won’t let me without a US number. I have tried setting up a VOIP with no success, can anyone please advise me? 🙂

Delete if not allowed but anyone have a number to T-mobile trunking support? Calls from our network in Wisconsin to T-mobile are failing. At&T says the problem is T-Mobile on TG AJ064067.

Hi everyone. I'm interested in installing a VoNR desk phone in my home office, and I'm hoping someone can help me figure out if this is practical and realistic. I'm far from a telecom expert, so please forgive my lack of knowledge!

T-Mobile provides both 5G SA and VoNR in my area. But, aside from smartphones, I haven't found any devices that are capable of VoNR. I initially wanted to get a cellular home phone base, but they all seem to be restricted to VoLTE.

I've also looked at 5G gateways with an RJ11 port, but these devices don't seem to be available to individuals. Interestingly, this restriction only seems to exist in the US market.

Finally, I've also thought about using a 5G WWAN card and dedicating a computer as a phone server. Some 5G cards are available with the Snapdragon X62, which natively supports VoNR. However, there seems to be a lack of software support for this idea.

Does anybody have any insight to offer me? Is this a practical goal? Or am I totally off base?

I have an existing cell tower in South Texas with a perpetual easement agreement from the '50s. Multiple mobile and internet carriers are on it. It has a very low annual payment attached to it. The tower company is open to negotiation due to needing to use my gravel roadway access.

I've done research, but would like input on rates, escalators, shared revenue, etc.

Thanks!

Techs, walk me through this....

I see a galvanized tower with 3,4 or even 5 triangular frames holding antennas.

Is each one of those arrays a different operator ? Mobile, ATT, etc.

And when I see a water tower with these rectangular boxes...that is the operator renting tower space from the muni ?

Tks !!

How many people in this sub grew up in this industry with electromechanical switching, analog data circuits and SF controlled circuits such as FXS/FXO?

What do you think will be the next big thing in telecom industry?

Hello everyone,

I work for a mobile operator, and I recently received a task from management to investigate how we can offer true unlimited mobile internet for subscribers using our 5G network.I am still learning this area, so I would really appreciate advice from experienced mobile core/network engineers, especially those who have worked with 5G NSA architecture.

Our current situation is the following:We have a 5G NSA deployment, where the data session is still anchored in the EPC side. From what I understand, user traffic goes through the usual packet core path, and in our case the DPI system does not clearly distinguish whether the subscriber’s traffic is actually coming from 4G/LTE or from 5G NSA.

The main question is:

How can we correctly implement an unlimited internet offer only for subscribers who are really using 5G, if the DPI cannot separate 4G traffic from 5G traffic? Some of the things I am trying to understand : should this logic be implemented on the PCRF/PCF side instead of DPI? Is it possible to rely on RAT type, access type, NR indication, or any 5G NSA-related parameter from MME/SGW/PGW? In NSA architecture, where exactly is the best place to detect that the subscriber is using 5G? Can this be done through Gx policy rules, QoS profiles, rating groups, or charging logic? How do other operators usually handle “5G unlimited” plans in NSA networks? Is it better to create a separate 5G unlimited package with FUP/QoS limits rather than a completely unlimited plan? What happens when the subscriber falls back from 5G to LTE during the same session? My concern is that if we simply make traffic unlimited based only on APN or DPI classification, then LTE users may also receive the same unlimited access, because the DPI does not know whether the traffic is from 4G or 5G.

Has anyone here worked on a similar commercial 5G NSA unlimited data offer?

I would really appreciate any guidance, architecture examples, vendor-neutral recommendations, or real operator experience.

Thank you in advance.

So I’m making a bit of an unconventional move and wanted to share it here and maybe get some perspective from people who’ve been in the field longer than me.

Background

I have a BEng in Electrical Engineering and an MEng in Software Engineering. My recent work has been software development and data analytics, white collar, desk job, laptop life. I also did a brief AV/low voltage stint right out of undergrad but left quickly due to a bad supervisor situation and never gave it a fair shot.

Part of what pushed me toward field work is honestly the AI thing. I got tired of being in roles that are increasingly in the crosshairs and didn’t want to keep competing in a space where the ground is shifting under everyone’s feet and my short contracts not extending after they ended. So I started applying to field tech roles deliberately, knowing I had minimal hands on experience, and just pushed my luck.

Turns out it paid off. I was unemployed since January and when I went in for the interview the owner of the company hired me on the spot. Didn’t say he’d be in touch, just offered me the role right there in the room. After months of rejection that meant a lot. I keep thinking he saw something in my background I wasn’t giving myself credit for.

Now I’m joining a telecom company as a Tier One Field Communications Technician working with RF two-way radio systems, microwave broadband, satellite, GPS/AVL, DAS/BDA, and vehicle mounted comms equipment which if you ask me is so cool. I relocate in about a week and start May 25th.

What I think transfers

My undergrad dissertation was on Software Defined Radio with an RTL-SDR dongle so RF theory isn’t completely foreign to me. I also have IT networking experience from my homelab, and was pivoting to a help desk position after I got laid off in January but the amount of rejections 😮‍💨, but I’m working toward my CCNA. And troubleshooting is probably my strongest skill overall. Engineering and software work drilled into me how to isolate variables, test methodically, and not guess. At the end of the day a fault is a fault whether it’s in code or a cable run.

What I don’t have is hands on field craft and I know it, but I do always observe and monitor when cable technicians come over to my basement for troubleshooting internet issues, such as adding a booster, adding a splitter from the coaxial outlet to 2 routers, testing the main line, terminating coax cables etc. No illusions about being ahead of someone who’s been doing installs for years.

Questions for people in the field

Where does this career actually go long term? What does a realistic day look like for a Tier One tech? And what resources do you wish you had when you were starting out?

Anyway. May 25th. Fort McMurray. Here we go.​​​​​​​​​​​​​​​​

Anyone affected by the recent Astound Broadband Layoffs? Let's connect here!

Hey! So i am a telecom engineer with 2 YoE (2024 grad) in an oil & gas EPC giant. I had not really planned on getting into this field i joined a conglomerate and i just was put into this industry. I am a Electronics engineer graduate btw i was really into embedded systems did internships in similar roles and had done lot of projects there.

I am very new to this industry i have exposure to telecom system design like TETRA Radio, VOIP, Fiber optic transmission, CCTV systems mainly oil & Gas EPC, what are some good prospective fields in this industry to pursue like in terms of compensation and availabilty of jobs? Do Telecom System Integrator (TSI) provide better compensation and exposure? Or is OEMs better?

Any kind of guidance or Advice is appreciated!

Thanks!

Most SMS I receive from signing up to websites and where they require my phone number and an otp code, it comes from InfoSMS. Even if I send myself a test message from twilio, it comes from InfoSMS.

Is something wrong with my phone number?
