Outgoing calls going not ringing on certain End Users (comcast)

So just seeing if anyone has run into this…

We put new Resident Call Boxes (Mircom) in a high rise client. These boxes take standard copper phone line only when NOT using their in house VOIP solution… They just directed us to use an FXS if using our own VOIP line to transition to copper to connect to the MIrcom call boxes…

We have a fully licensed FreePBX at this site. We just setup 2 new extensions for a CISCO SPA112 and plugged the 2 call boxes into the 2 FXS ports on the CISCO… Zero issues, works great…

This deployment uses SipStation trunks… Everything has been working great for about a year since we installed it.

Over the last few months, we have been receiving complaints from this client that the residents in the building that have Comcast Digital Voice landlines in their condo/apartments… and that number is programmed into the call box for these specific residents, the call never rings on their house phones and the person at the call box gets the Comcast voicemail… Even though these residents have had techs out, confirmed forwarding and comcast vm is turned off.

If a cell phone or different VOIP service is called like another Sipstation or Nextiva, Verizon PSTN, etc then the call rings through normally and person answers, presses 9 and door unlocks…

Has anyone see this issue ??? Where calls from FreePBX/SipStation to Comcast phone numbers go straight to VM? We did submit a proper LIDB request to SipStation when we setup this line and they applied it correctly. The correct client name comes up on my office CallerID when they call me…

Thoughts/suggestions? Anyone seen this? Doing some googling, it seems other comcast customers are experiencing this issue as well. Just seeing if any of you guys have seen or heard of this…
