(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?

Sincerely

Through test lab, I found some results.

(1) We only need config CUBE on HQ1 Gateway;

(2)The really question is that if a H323 call from outside to a CME, we can't pikup the call from a CIPC(sccp) phone controlled by CME, is there some solution?

(3) We don't need a MTP, and how media stream session establishment determind by media mode flow-through or flow-around
