System is 2000 IPS about 5 years old. Has IP stations and TDM stations (both Dterm and analog).
Just out of the blue yesterday, IP phones lost both way audio on phone calls to any destination other than other IP phone.
In other words, pure Peer-to-peer IP calls were still fine, but IP-to-TDM calls had no audio. Made an outgoing phone call from a TDM phone via a T1 trunk, and that had no problem.
We were in the middle of a conference, when they were trying to use the system, so there was absolutely no time to test and trouble-shoot. Only thing could be done was to poke it in the eye - reset.
That handled the problem. But what happened?
Any ideas?
