Hi , Self is trying to implement Following scenario using PJSIP and asterisk : There are two Asterisk 16 servers. One server is connected to two SIP Phones A & B. Other Server is Connected to Two SIP phones C &D. We want created conference room say 1000 in server 1 and A & B join that. We want to send conference data over multicast from Server 1 to Server two using PJSIP trunk for C & D which are also participant of the same trunk. Kindly help if someone has done such an implementation Thanks in advance. -- Regards , Mohit
