This issue is half solved under you suggestion. But I still have issue:
Scenario Below: A 3rdparty SIP phone(Xlite) controlled by a CUCM Server, Add a H.323 gateway(named HQ1) to this server, A software phone(CIPC) Controlled by a CUCME(named PSTN), CUCME interconnected with HQ1 use H323 protocol. Qeustions Below:
(1) shall we config CUBE on both Gateways?
(2) I can ring CIPC from SIP phone, but I can't pick up CIPC phone; and everything thing is ok regard with the opposite direction.
(3) Can you point out how media stream session established between the two phone? Need we a MTP?
