In my company we are working in a new IP Telephony solution. This solution includes CUCM enterprise for 1.100 users, two MX200 endpoints and two 2911 gateways. The client wants to include multiconference sessions between Video telephones (8941 included), jabber and the MX200 also with the share content option. How do I can to enable this requirement with this CUCM+2911 solution? what is the required PVDM? is it possible to share content under this configuration?
