Hi, can someone please help me with this problem?

I have CME talking to CCM via a ICT trunk. Codec is set to be g729. All calls work fine.

However when i try to call the AA app on IPCCx from the CME box, the call fails. I have set up a transcoder at on the 6608 blade, but to get this to work it i have to check "MTP Required" on the ICT Trunk. Once i do this everything starts to work.

However i have noticed that all calls from CME to CCM via the ICT trunk now uses the transcoder. Is there any way around this? I have been racking my brains for the past few hours trying to think of something but came up blank.

Any help would be greatly appreciated.

Many thanks,

Gary.
