Hello all, I need a signalling server, what I need it to do is the following, there are two scenarios: The network structure is this: ________ |RTP BOX |____________ |________| __|________ | END POINT | |___________| ________ | | FS |____________| |________| Scenario 1: Generate a call to and end-point specifying dynamically the ip/port for rtps and report back the end-point's rtps's ip/port. Scenario 2: Receive INVITES and report them walong with its rtp's ip/port and answer with a dynamically assigned the ip/port. The rtp's ip/port assigment is done dinamically on another box which soulh communicate with FS via a socket or a script. Does anyone knows wether it is possible at this pont? if it is, how go about this, pointing me in the right direction? I would prefer to do this via scripts (Perl, php) Thanks everyone.
