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

SHAKEN testing services
by nathana＠fsr.com June 29, 2022

June 29, 2022

Is there a list somewhere of third-party SHAKEN testing services available to the public? Although our own STI-VS can validate our own PASSporTs signed by our newly-minted private key, I want to verify what the world at-large is seeing before I flip the switch on for all outgoing calls (& potentially cause a bunch of problems if it turns out that something's wrong). So I'm envisioning something along the lines of a phone # one can call, and then get a report back of whether the terminating provider was able to validate the contents of the Identity header or not, and if not what the exact problem is. (Obviously the path between us and them would need to be IP end-to-end unless out-of-band SHAKEN is in place for the PSTN "glue" circuit.) I've found a couple, but the results for the ones I've tried (e.g., IDT BYOC) are woefully simplistic and don't really explain what went wrong if something does go wrong. Thanks, -- Nathan

STIR for intra-net calls
by nathana＠fsr.com June 28, 2022

June 28, 2022

What's the consensus on signing calls that don't leave your own network? Are operators bothering with this, or generally only computing & attaching PASSporTs to calls that terminate off-net? Thanks, -- Nathan

Devices that may violate NDAA

*' Sec. 889(a)(1)(A) required the federal government, as of August 13, 2019, to not ?procure or obtain or extend or renew a contract to procure or obtain any equipment, system, or service that uses covered telecommunication equipment or services as a substantial or essential component of any system, or as critical technology as part of any system.?' * I am curious how you're handling CPE (i.e. handsets), for which you are responsible, that are already in the field that is from, *or contain components* (more pertinent to our situation) of the prohibited manufacturers (Huawei, ZTE, Hytera, Hikvision, and Dahua). Are you notifying customers? Replacing or recommending replacement? Handling differently for private enterprise than for the government? Thanks, Pete

Peerless issues this morning
by dovid＠telecurve.com June 20, 2022

June 20, 2022

Anyone having issues with SIP traffic to Peerless? We had an issue where it seems that they were not getting any of our 200 OK', ACK's etc. With most of our ISP's the packets were not flowing. With one smaller upstream carrier which uses L3 upstream it is working. Peerless NOC answered and told me they had a network issue in Chicago and that's about it.

Comcast rejecting port requests for 4 months
by aaron＠heyaaron.com June 16, 2022

June 16, 2022

Hey everyone, We have a large SIP trunk with Comcast with around 275 numbers attached. We've been trying to port about 200 of those numbers to another provider for the past 4 months to do some geeky things that Comcast doesn't support. Due to reasons only known to Comcast, there are 5 different account numbers vaguely associated with those phone numbers and I keep getting wildly different answers from Comcast staff. One is for the EDI circuit. One is for the AdTran. One is for the SIP Trunk One is for "master billing" One is a "hierarchy account" The winning carrier has submitted the requests with every possible combination of account number and 'CPNI code' (Comcast's account PIN) we have along with all our addressing information, copies of bills, etc...and Comcast keeps rejecting it with zero useful information. i.e. bad address, bad PIN, bad account number, etc... Every time I even mention "porting out" to a Comcast rep, they say "FCC regulation prevents us from talking about it". The winning carrier has had so much trouble, they finally sent me the "port order number" and said "call Comcast and talk to them about it. Good luck." Of course calling the Comcast porting number gives you a short recorded message about "due to COVID, use some portal click". I'm technically a contractor for the end-user and not a phone service provider, so I don't have access to whatever portal they are talking about. It's been absolute hell. Any thoughts on how I can get Comcast to get their crap together? I've never had so much trouble porting numbers away from a carrier. -A

SIP Trunk Failover
by calvin.ellison＠voxox.com June 11, 2022

June 11, 2022

If your SIP trunk provider were to offer failover, would you prefer to configure that failover per DID/TFN or for the entire SIP trunk? Failover might include another number, an IVR, voicemail, a ring group, another SIP trunk, a voice reject, or something else.

iNum and UN numbers via ex Voxbone now Bandwidth
by compuwizz＠gmail.com June 10, 2022

June 10, 2022

I believe the iNum project was shutdown by Voxbone before Bandwidth bought them, but I didn't see anything about the UN +888 country code numbers that Voxbone hosted also. They used to be reachable via ENUM but I'm not seeing records for them anymore. Does the UN range exist anymore? I do see the destination listed in some vendor rate sheets with varying pricing from normal to astronomical. The test numbers I have don't complete. FWIW I also see the iNum range +8835100 in rate sheets. ~Jared
