We are trying to interconnect a CUCM 6.1 with an IP-to-IP GW in order to translate H323 messages to SIP (Sip Provider).
The problem is that we are not able to place calls with G729(MTP) but only G711.
We need Fast Start with G729 MTP because our Sip Provider supports "Early Offer"
Is there any specific config that has to be done on IP-to-IP GW in order to enable
fast start ?
