SS7 Landscape
by voiceops＠ics-il.net Oct. 24, 2023

Oct. 24, 2023

We currently get our SS7 via TNS. I (maybe incorrectly) understand them to be a big dog in that space. I've had two major problems with them in six months. What are my alternatives? Are they less pleasant? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Activation Timing
by voiceops＠ics-il.net May 2, 2022

May 2, 2022

I'm trying to develop some new rules for dates we choose for porting. We have to build outside plant for most customers to accommodate their turn-up. The customers generally don't understand why the phone isn't alive when the tech is on-scene, but the tech has to go on-scene to build the infrastructure. Is it reasonable to choose a port date that seems like it would work, then bump the activation day by day if OSP has encountered any issues? I would like to think that by not *activating* the port and rescheduling it for the next day, everything would still work correctly, but I'd rather be right than lucky. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

Trading Partner Agreements and Porting: How Long to Complete?
by beckman＠angryox.com April 27, 2022

April 27, 2022

I've got a Metro by T-Mobile customer (SPID 158H) that wants to port their number. Our carrier doesn't have a current Trading Partner Agreement (TPA) in place with Metro. So, they told me they submitted one to Metro on March 30, 2022. It is now April 27, 2022, and as far as I have been told, Metro has not responded to nor signed the agreement, preventing the customer port for almost a month now. I don't know much about what a TPA is, why or what it is needed for, and how long by FCC rule it must be completed within. What I do know is that the FCC does not look kindly upon carriers who deny porting to consumers. Can someone educate me about: - What is a TPA and why is it needed to Port numbers between carriers? - What FCC Rule (if any) states the maximum amount of time before a TPA is signed? - How does a consumer escalate within their carrier in order to force the completion of the TPA and get their number to port? - What does a non-Tier 0 carrier do to escalate conflicts between their carrier vendor and another carrier? - What have I stated that isn't accurate, or what am I missing? Thanks Beckman PS -- If anyone named Frank is listening and managing TPAs for their carrier clients, I'd love to hear from you! --------------------------------------------------------------------------- Peter Beckman Internet Guy beckman at angryox.com https://www.angryox.com/ ---------------------------------------------------------------------------

Remote LEC Support
by voiceops＠ics-il.net April 26, 2022

April 26, 2022

Are any of the larger operators on the other side of a tandem switch worth a darn to get support on a current issue through? I put in a ticket with Frontier (tandem operator), but almost all of the time, they end up just saying that they opened a ticket with the operator on the other side (which I already knew had problems) and then wait for resolution. For my troubles, I get to wait another several hours. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com

SIP trunk providers emitting RTP packets containing wrong number of samples
by Liudy＠bukys.org April 19, 2022

April 19, 2022

My company (a SIP equipment manufacturer) has noticed a sudden flurry of problems related to RTP streams containing some packets with the wrong number of samples (different from what was negotiated). Our equipment negotiates 20ms packets, we're seeing the emission of a few 5ms packets with MARK bit set, before the 20ms packets start flowing. I theorized that some vendor's SBC or Media Gateway has released software that causes this. It has erupted at multiple customers. I thought there was no commonality of carrier or trunk provider, but today I heard a report that T-Mobile is definitely implicated and reproducible. Other sources are possible too. Has anyone else noticed this? Does anyone have a good contact for SIP-related matters at T-Mobile?

Waiver request for fees for Reassigned Numbers Database
by calvin.ellison＠voxox.com April 5, 2022

April 5, 2022

More data for our Call Analytics/Anti-Robocall Filter: the Reassigned Numbers Database. In our case, we'd want to use this for real-time call analytics on every single ANI & DNIS that crosses our network, querying the database using to determine if a number should be in Aging status (disconnected within the last 45 days). I've asked our counsel how to "me too" this waiver. Although this waiver calls out the "pull versus push argument", we'd need the database on-premise in order to minimize post-dial-delay. Is anyone interested in filing a joint waiver?

Anyone else have billing problems with VZ?
by marylou＠backuptelecom.com April 4, 2022

April 4, 2022

I have a client that has been dealing with multiple unresolved billing disputes with Verizon for many years now. It has gotten to the point that attorneys and the court are involved. It would be helpful to know if other competitive carriers are experiencing similar issues with Verizon's bill dispute practices. If your company has filed a bill disputes with Verizon and you don't feel that it was handled in a timely and appropriate manner, please e-mail me privately.
