Stumped on this one. Our Internet service went down, part of the big Comcast outage in the northeast. Didn’t failover to the redundant carrier, but that’s another issue.
While Internet service was down, we experienced one-way audio on outside calls. Odd, because our voice is delivered via AT&T SIP trunks with an MBG. We have Teleworker phones connected via a second MBG which resides in a DMZ.
We’re running two HX controllers with PS-1 servers, MiCollab AWC and CSM. It makes sense that the Teleworker phones went down, and no one would be able to web into the AWC. Otherwise, nothing in the phone system touches the Internet. But when Comcast came back, one-way audio went away.
Any thoughts?
