Voice interrupting at simultaneously speech.

Hello!

We have the next problem:

Two users speaks on 7942G phones through Call Manager. If first user speak something and second user speak some words at the same time, then each user hears interrupted voice of another. At 7940/third party devices the same problem.

Can it be fixed on Call Manager?

Re: Voice interrupting at simultaneously speech.

RTP is sent directly between endpoints, unless you are using an MTP/TRP which would be weird for an internal call, so, no, this is not something you fix in CUCM.

That sounds like some network issue you're having with the RTP, or that you're not using full-duplex

Re: Voice interrupting at simultaneously speech.

There have been defects over the years about speakover causing half-duplex behavior in the phone DSP. Are you running a current phone firmware load? If not, try updating it.
This answer assumes you are *not* invoking an MTP as Jaime mentioned (eg RSVP Agent of Trusted Relay Point).

Is the issue is observed with other models of phones in the same network?
