We moved our corporate HQ to a new location that is being serviced by a Comcast PRI line (split off from our Fiber connection)
When we set the system up, everything worked fine, and still does for the most part, however calls INTO the system receive no ringing sound when calling a party within our organization.
If you were to call my extension directly, the phone rings once on the earpiece, and then there's dead air until either A) I answer, or B) my voicemail picks up.
Calls out have zero issues. This issue is only present for people calling INTO the company.
Comcast, Dialogic, and our IT vendor are all shrugging - no one has anything I can check or any settings that need to be changed.
Sequence of the PRI:
Comcast - > PRI -> Comcast Equipment -> Handoff to our Dialogic -> Dialogic to OCS Cluster
I can't find any settings in the OCS setup that would fix this particular issue, and since no one was paying much attention until the problem was reported, we don't know if the ringing ever worked at the new building, or if it is a recent issue.
