Interclustertrunk between CME 3.4 and CCM 3.3(4)

Hello,

I´ve configured a Interclustertrunk between a Callmanager Express 3.4 and a Callmanager 3.3(4).

A Call from a CME-Phone to a CCM-Phone, works without any problems.

A call from a CCM-Phone to a CME-Phone results in a Call-Setup, that is disconnected after one or two ringback tones.

The only hint I found was in Callmanager Trace for MTP:

VoiceStrm|kDeviceDriverError - IP voice media streaming device driver error. Error:MTP: AId 1, CId 16777237, PId 17085265: Can't Mix Codecs.

However I´m using G.711 ulaw at both sites.

What could be the reason for this behavior?

Thanx for any hint.

Geri

When you configured the ICT did you check "MTP required", make sure it is unchecked. Is the ICT configured correctly? Is the IP address correct? Is the Partition applied to the route pattern pointing to the route pattern listed in the CSS of the phone?
