[cisco-voip] Weird call in VM..... Explain that?

[Gr]

I came across something like this once. Our Ops mgr reported he received a call from VM port and as he answered the call he heard voice recording of the GM of our company and then was able to listen to a talk going on between GM of the company and other person. It was like an old analog line cross-talk. We were really surprised something like this can happen in IP.

Never got to troubleshoot that due to other priorties and never happened again.

In this case it was a legacy VM device that DPA that wasn’t filtering out audio streams that were not from the current audio session and the 7970 the defect that when unregistered, would continue to send an additional audio stream (CSCsj99361).
