When you receive a RQNT (request for notify) you include the action to be taken for different types of events. The action can be a stripped down RQNT that provides new instructions, just like a new RQNT packet. This can include parameters. I've heard it call encapsulated parameters but I believe that the spec calls it embedded. YMMV. FWIW, Asterisk's MGCP support is a bit dubious and definitely not what the spec intended. The spec intended for a call agent to manage various media gateways and orchestrate what was going on. Asterisk is a media gateway that attempts to be a call agent for itself and another media gateway (the phone) with interesting but limited results. It probably will never operate in a real MGCP environment unless chan_mgcp is implemented as a media gateway. Right now, it just provides a hack that allows MGCP phones to hit it...sometimes. Good luck. -- Jayson Vantuyl _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
