[cisco-voip] Crosstalk or Merged VoIP calls

[Voll, Scott]

Why stop at 5.0.  why not go to 5.1? most of the bugs are fixed in 5.1

We are running 12.4(9)T2 on the 3745's/3845's platforms and running 4.02
CCM. We are in the process of upgrading to CCM 5.02. .

We had a VGW that interconnected the PBX and CM.  running CM 4.1 and
Unity 4.0.5 on both the PBX and the CM side of things.  I think DSP
problem could very well be a possibility.  Have you upgraded?

Nope, no QSig. Just standard North American PRI signaling here.

What version CCM were you using?

What were you using for voice mail?

Where there voice gateways involved in your seni

 

Our first thought was this was a typical DSP problem but how could a
live conversation get re-routed from it's orginal router to our VM
system and be merged in to an exsisting incoming VM call that is being
left for a user. This one will go down in the history books as then one
that stumped the world I think. I can only hope that someone out there
has see this and can point me in the right direction. 

 

Thanks,

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
