I currently have a CUCM7 site and some remote CUCME branches and PSTN gateways.
All the phones, in all the infrastructure use G.729 (even between phones in CUCM HQ).
- between CUCM phones with G.729 i can make conferences (even knowing that Software Conference Bridge only supports G.711). Are this using Cisco IP Phones capabilities to make the conference?
- if i try to conference with remote CME IP Phones or PSTN users, it won't work. For this i'll need hardware conference resources? Can i tell CUCM to use remote gateways (CME and PSTN GW) resources to conference?
thanks in advance
