Comcast Voice Routing Contact?

Apologies for cross-post - no luck using the VoiceOps list.

Hello, we have a fun issue we are attempting to troubleshoot with an end
user having problems reaching local businesses utilizing Comcast (unsure if
the end product is POTS over Coax or VoiceEdge). SPID: Comcast IP Phone/1
The calls are not originating via their usual routing on their receiving
end and some alternative routing seems to be in place where they are
failing to cell phones.

I'm checking to see if any Comcast folks are lurking that could potentially
help or shed light on what is occurring or what the problem seems to be. We
tried to suggest to our end user to have the local businesses reach out to
Comcast - going through tier 1 support, rolling a truck, etc. It's still an
issue (surprisingly) as I'm not sure this could be solved by a field
technician if it could even be communicated well enough upstream to who it
would matter to.


We are attempting to go the usual channels now with the carrier we are
originating the calls from and seeing if they can engage further
engineering upstream but I have a feeling this will fizzle out. The losing
carrier we ported this customer from last year is of no relation to Comcast
(at least on the outside), but I'm unsure if they're still in the call
stack or if there was some sharing of resources on that end when they were
still housed there.

**Update 04/11 - origination route to term partner support path is not
looking hot👎
Region of concern is northern Illinois

Please reach out off-list if you can be of assistance and I can share more
information. Thanks!
