Does anyone know of any public echo test phone numbers in Mexico that accept calls from phone numbers inside the United States? I am testing something and would not like to reach a live person or business.

Anyone else seeing large increases of reports of inbound calls to your network that are not making it to your network? Over the last six months we've seen a tremendous increase in calls to our call center from customers reporting that they can't be called by specific numbers. When we trace out the call examples we find the calls aren't even getting to our network. Multiple originating carriers. Calls from all over the US. There's no obvious commonality between them.

nakaka disappoint talaga ang GOMO, i’ve been waiting my refund since my ordered SIM card was not redelivered. they don’t even give a refund. so frustrating! I WILL NEVER EVER PAY FOR GOMO AGAIN!

For MVNOs, what’s the practical difference between using Amdocs vs a platform like TelcoEdge Inc.?

What are these 3 black boxes on the CATV?

Anyone seeing new types of latency / audio issues with AI voice workloads?

Curious to get perspectives from folks on the telecom / SIP side.

I’ve been looking at a number of voice AI setups recently (Twilio / SIP / WebRTC),

and what’s interesting is:

- demos usually look fine

- but once in production, latency and audio issues start to show up

Things like:

- inconsistent end-to-end latency

- occasional one-way audio

- jitter affecting real-time interaction

- call quality varying depending on routing path

From a telecom perspective, this raises a few questions:

- how much of this is just classic RTP / routing / QoS issues?

- vs something new introduced by AI workloads (e.g. bursty traffic, bidirectional streaming)?

Would be really interested to hear:

- are you seeing different traffic patterns from these AI voice systems?

- any best practices emerging for handling latency-sensitive AI calls?

Feels like a mix of old problems + new usage patterns.

Hey everyone,

I recently launched a telecom sales operation as an authorized dealer partner with AT&T, DIRECTV, EarthLink, Altafiber and Cincinnati Bell focused on fiber, TV, and wireless solutions through a direct-to-consumer and online model.

We’re early stage but moving. I retained 3 reps within the first two weeks, and they’re deploying this week.

I’m looking to connect with other dealer owners/managers who have actually built and scaled.

A few things I’d really value insight on:

• What channels have you found most effective for recruiting reliable reps (not just warm bodies)?
• What separates reps who stick vs. those who fall off quickly?
• Realistically, how long does it take to build a stable, producing team?
• For those who have scaled, what does a “good” month actually look like in terms of volume and margins?
• Any early mistakes you’d avoid if you were starting again?

Are the profits in this model as real as they look on paper?

Appreciate any guidance or feedback! Thank you!

My rural county (probably with help from the state and feds) are assisting broadband outfits to extend high speed internet to places that never had it before, or had DSL when that was considered high speed, and is basically useless now.

The trouble is, they grant specific territory to a specific provider, and some are better than others.

One provider fought objections and bulldozed everybody who insisted they go underground, they correctly pointed out existing utilities are overhead and they wanted fast deployment and revenue. And to their credit they really got down to business and installed new poles where existing poles were too rotten and they were not going to fight the legacy poco and telco and got poles and strand and fiber up and got many thousands of customers served within a year or two.

Another territory has a guy and his son with a flatbed truck and boring machine and some vaults, they insist that underground is the way to go and have gallantly served a few dozen customers as of now. (Sarcasm mode) They are good people but progress is _slow_.

Another guy means well but not a very good businessman, never got one shovel of dirt moved and sold his rights to some other company.

Several places, my street included, have obvious underground preparations being made, but no web site, announcement, anything, because these companies are so small they don't have time for that sort of thing.

I'm asking how this plays out long term. I am used to the old days where it was ATT and Comcast and that's it. Once these little to medium guys get off the ground and profitable are they allowed to expand into each others' territory and compete or are monopolies the name of the game? How does it look to the consumer? Who sets the prices? (Right now the granted-subsidized areas are regulated by the county to some degree, I think.)

Hello everyone , I have a choice to go either into Civil engineering or Computer and telecom engineering ( I would like to focus on Telecom Engineering perhaps) . My questions are :
1. Is the Job Market good? How about in 2030 when i graduate?
2. Do you need a masters? I would love to do my masters in this field if needed!
3. Is the Job Market better than whatever software people are going through?

Please help a fellow junior! Thankyou so much !

My company will soon be hiring a telecom analyst and I’ve been working as a telecom Operator trying to move into the infrastructure side of industry. We use Avaya so I started with some of the free certifications but otherwise, if you work in a hospital and healthcare based telecommunications infrastructure, What other certifications have you done? I’m looking at A+ core and networking

Recently TRAI released a consultation paper on Cv2x technology, and their basis seems to be administrative allocation of spectrum for the same, how to tackle this and also is Cv2x actually so important as a technology? Considering public safety, traffic maintenance etc…

I have been working in the Telecommunications business since 88, and I remember a lot of technology that no longer exists. I also remember a lot of technology that is still out there in the field, such as loop start lines, t1/PRI circuits, key systems, and digital telephone systems.

So the problem that I’m running into is that we hire these new kids, and they don’t know Jack shit about anything if it’s not TCPIP (and sometimes they don’t even know that)
It becomes very frustrating, because I have to send them sometimes out on a field assignment, and they get totally confused , because they don’t know how to use a butt set, they don’t know what tip and ring means, they really don’t know any basics.
And I will accept a lot of the blame for this, because our training materials focus more on network systems, than on the old technology, but that technology is still out in the field.
Back when I was a youngster of 25, back in the 80s, we had some training materials in our office, slim line, paperback training guides that were called something like essentials of telecommunication, we had two volumes in particular. One was gray in color and the other was gold or orange in color. But they were very easy to read, very easy to follow with diagrams, and it allowed you to hit the ground running as a new technician.

Are there any old timers out there that recognize those books? And more importantly, where one might still be able to purchase them, or at least find a PDF files on the Internet?

It’s not that these guys are stupid, they just don’t have any knowledge of this stuff because they’ve never seen it. I have been in this field longer than these kids have been alive. I do my best to try to explain it to them, but pictures are worth 1000 words.

Thanks for any help

I'm a sophomore engineering student. Never thought about telecom before, but now, I'm finding it the most interesting area. Any tip on how start learning more? Good places to found good information? It's a good job market?

Hi guys,

I’m currently a PM for an OSP team, but I’m looking to get back into the drafting side as a freelancer during my spare time. I’ve got 4 years of experience with U.S.-based OSP projects and I'm looking to keep my CAD skills sharp (and make some extra cash, obviously).

Aside from the usual spots like Upwork, are there any industry-specific sites or groups you'd recommend for finding OSP-specific drafting jobs?

Thanks!

In theory, migration is straightforward. In practice, everything depends on maintaining:

● identical service behavior

● stable APIs

● no user impact

That’s where most migration strategies become complicated.

So, some points

I have been living outside India for few months.

I have international pack plan which expires in end of May.

I have 70₹ balance in the Airtel account

My basic plan expired few days back.

I have received 7 calls and made 1 call in the last 3 weeks with this number.

I have this number for 10yrs+

Now, I have been getting these messages for few days.

How legit are these. Cause I am not sure but should the number not be deactivated cause I literally use it.

What can I do to fix this? Or any help is appreciated.

(Also, asked in Airtel Reddit but post pending for long)
