[cisco-voip] Crosstalk or Merged VoIP calls

[Voll, Scott]

I have seen this when we had our CM and old legacy PBX connected.  I
always thought it was the PBX screwing something up..........  Are any
of the Connections QSig?

Has anyone seen crosstalk or calls getting merged in a VoIP environment.

We run a very large VoIP environment and have seen 3 cases of this.

 

Case #1: 

Two routers in two different locations.

Location 'A' has a user on an IP phone outbound to the PSTN.

Location 'B' receives an inbound call that gets forward to our own
voicemail system via a Cisco 7610 DPA.

Our voicemails are delivered to our email the form of .WAV files.

The .WAV file delivered to the user is of the conversation that location
'A' user is having.

The .WAV file recorded a portion of their conversation.

How is this possible? The two voice streams don't exist on the same
routers. How could they and where could they have mixed.

 

Case #2: 

One router in one location (that we know of..lol).

User dials in and this time leaves me a voice mail. The voice mail I get
is not what he left but of another live conversation of another party. 

 

The only common parties involved here are CCM 4.x cluster, Cisco
DPA7610's and our voicemails system.

 

Any help would be appreciated.

Cisco is baffled as well.

 

Thanks, 

Mike
