I hope someone can help me, this is the problem. I have a CUCM 8.5 whit a CUBE as h323 gateway. CUBE uses SIP to connect to an asterisk system, like this:
CUCM ---h323--- CUBE ---SIP--- Asterisk
Calls work fine, but when i try to transfer a call in CUCM side, it dont work. I was trying modified mtp requiered, but using mtp, i press transfer and nothing happen, if I not use mtp, i press transfer and call get down.
CUBE config is attached, I would really appreciate any help.
So i suppose asterisk users are using g729 codec or cube definition has been forced to use this codec.
Configure IOS mtp service on cube to use g729 and assign it to a new media resource group on cucm. assign mrgl to h323 gateway.
Hope this helps.
