Caller on hold and hear other calls over the MOH

Hello Experts- Can anyone help to explain how this can happen?

We've had some reports from our callers that they are able to hear other conversations (our internal side) while waiting in queue over the MOH. Of course I cannot reproduce the problem at will. The hold steps are very straightforward in our queuing script. Of note is that one of the conversations was that of one of our users who is not even configured as an agent for IPCC. How can this happen?

Call Manager 4.2.3

IPCC Express 4.0(5)

Thank you in advance for any help,

Kelly

Are you multicasting the MOH? If so, what IP/port?

Hi-

No multicast for MOH.

That's very unlikely from an IP side. I would be suspicious of the telco circuit, especially if they are analog.

There are no analog circuits involved in this scenario.

Check out CSCsj99361,

This defect affects 7941 and 7961 phones, where duplicate RTP stream is being send to other phones. An ip phone will be left in a state such that it will continue to stream RTP packets out to a prior destination even after the call has finished. Every time the ip phone users is on a call, two RTP streams will be present both with the user's conversation audio.

HTH,

Chris

Many thanks! I'll check this out. This makes the most sense.
