I am sending out a multicast page using the following in my dialplan:
Everything works great, but I had a question about SIP and SDP:
Should I be seeing a SIP/SDP message from the asterisk server containing media information and the multicast IP address? On wireshark, I see SIP/SDP from the admin phone I am using to dial the extension and initiate the page. But I never see a SIP/SDP message with the multicast address sent from the Asterisk server to the endpoints. Maybe I misunderstand how SIP and SDP fit into the messaging scheme.
Can anyone tell me if I should see SIP/SDP coming from my Asterisk server to my endpoints? I hope my question makes sense.
