Auto Attendant Transfer issue with CMM

[wwmarcww]

CM is 5.2.1 with CMM

auto attendant is built and a couple button options set to transfer the call to a station that forwards to a cell phone. When that option is selected I can see the CMM trunk make an outbound call to the cell phone. However there is no audio passing in either direction. When the far end picks up, the call drops. When calling the station directly the call forwards and audio passes with no problems.

Also, if the call transfers to a extension that has a physical phone on site, the audio works right away with no problems.

I also changed the extension the AA forwards to into a VDN/Vector. This works a little better as the call stays up when the far end answers, but the audio will not pass until the audix drops off the call and completes the transfer. A trace shows as soon the the Audix trunk goes idle, the audio establishes.

The traces show communication happening between regions 99 (audix) and 1 (CM). Looking at both NR forms, they both know about each other and are set to use the proper codec set for communication. Any other ideas on what I can check out? I know it's audix causing the issue, just not sure why.

My other option is to start using vectors and announcements for attendants, but I would rather avoid that if possible.

What is the codec that the network region is using on the call forward to the cell phone?

I would add g.729 as a 2nd choice if not there and then retest

G279 didn't help.

I ended up just making the options that needed to be forwarded to cell phones into VDN/Vectors that had a 3 second wait time with ring, then route to the cell phone. That 3 seconds of ringing gave enough time for Audix to disconnect and allow the audio path to open up.
