    Hello,

     

    I have made an integration between CCM 4.2 and OCS 2007. The Signalling is ok and voice is transmitted two way (no problem with SIP or RTP ports).the problem is very high noise level for voice in direction of Microsoft Communicator to cisco phone.

     

    Anyone can advise?

     

    Thanks Smile

    Anon,

     

    This sounds like you may have a problem with a MTP on the Cisco side. If you are using a software MTP this may be the cause of the noise. Best to use an IOS enhanced hardware MTP for SIP trunking or H323 gateways that require one.

     

    Cheers
