Avaya calls to CUCM 8.6: Call Park/Hold Fail

This may be similar to the issue I posted here:  https://supportforums.cisco.com/message/3496110#3496110

4 digit dialing from an Avaya system to a CUCM 8.6.2 server works fine, the Avaya is set as an h.323 gateway in CUCM.

Once the call is active if the Cisco phone places the Avaya caller on hold they hear no hold music and the call stays active until the Cisco phone tries to retrieve it.  Then it's a fast busy on both end.


The same thing happens with calls placed on park.

Any suggestions?

Have you already checked the MTP required on H323 GW??

Hi

Are you using G711 or G729 for these calls? If using G729 the CUCM software MTP cannot be used as it only supports g711, you would have to use a gateway-based MTP.

Try setting the calls to G711 to see if it works as a test.

I am using gateway based MTP and it's registered to CUCM.  Tomorrow I may have a chance to change the region settings to allow for g711 calls only.

I'll let you know how I make out.


Thanks!
