Calls from Comcast to DN in Nortel cs1000 blocked

[Etown]

Morning, I have a CS1000 7.5 . We have a T-1 built and attached to a server with DID pointed to it . This is for dictation purposes. All works fine unless you are calling from a Comcast owned phone number. I this case you get reorder . We had this issue a few years back and it was resolved by Comcast. Has anyone experienced this before ?

First of all if this DID # is on a PRI then you can monitor the d-channel to make sure the call from a Comcast Customer is even hitting your switch, my guess is it is not. So yes, more than likely a Comcast issue with them not having that DID # in their database.

Thanks for the reply , D-channel option is not there . There are 10 + T-1's involved way to much traffic. I turn it on and it will flood my TTY port . I was hoping someone worked with comcast and knew what on there end was causing this.

In the Route data Block, what is the DSEL set at? If it isn't 3VCE, change it to 3VCE and test. can be done on the fly, no down time

GHTROUT , already there , again everyone out there can call except Comcast customers. I am hesitate to make a change in the PBX for that reason. Do not want to break 2 to fix none.

It's a Comcast issue, not a PBX issue. If every other carrier can call it then there is a problem in the Comcast database. The calls come in on the same trunks as all the other carriers.

Were these DID numbers ever owned by Comcast? The reason I ask is because if you do a search on your issue you'll see many times that people who moved from Comcast owned numbers to another service and took their number with them had the same issue. Anyone in the world could call them except anyone that was using Comcast. Here's an example from as far back as 2009.

This part of the article makes me laugh. What the hell was AT&T thinking?

At one point, an AT&T technician visited the Maliches' home and replaced all of the phone wires in and around the house.

"He even replaced the wires going into the box down the street," Bill Malich said. Still, Comcast phone customers could not get through.

well at least you can say he tried or just needed some overtime money. Wonder why he didn't suggest changing the phones after the new wiring did not work?

Telco / LD carrier issue. Put in a ticket with your PRI provider and let them figure it out.
