Re: [SR-Users] IMS early media

Hi Mojtaba. I implemented the AS way and was able to play sound to the caller but In order to continue the call and send the invite to SCSCF I need to use proxy in the Dial application which is a problem (Asterisk is B2BUA not a proxy). I found this old question here https://community.asterisk.org/t/how-can-i-configure-asterisk-to-act-like-a… that describes exactly the same issue. Here is my dial plan: exten => 972551000002,1,Progress() exten => 972551000002,n,Playback(vm-starmain, noanswer) exten => 972551000002,n,Wait(3) exten => 972551000002,n,Hangup() ; This will send the call to the pcscf again ; exten => 972551000002,1,Dial( SIP/972551000002(a)mnc001.mcc001.3gppnetwork.org,20); ; This will send the call to scscf but it will be rejected as domain not supported ; exten => 972551000002,1,Dial( SIP/972551000002(a)scscf.mnc001.mcc001.3gppnetwork.org,20); Can I use kamailio as an AS and implement the same ?

If you choice the first way, i think it is very simple and strightforward because you just use early media functions on your AS. For example in Astrisk you could use Progress application and 'm' option in Dial application in your dialplan. In second way you should check in Reply-Route block,if you got 180 ringing, you have to use rtpproxy-stream funtion for doing sip early.
