I have configured Kamailio as dispatcher for Asterisk, if I am logging in to kamilio with webrtc can make calls with Asterisk and everything goes fine but when I try to make calls from Zoiper my asterisk box says that :

[2019-02-19 08:45:15] WARNING[4649][C-00000008] chan_sip.c: Failed to receive SDP offer/answer with required SRTP crypto attributes for audio

I have explored over the internet but nothing found, please help me to modify AVP in such a way that RTP request gets processed by Asterisk.

the details you provide here doesn't give any clue of what is the real
problem, where and why, so likely nobody can really help directly at
this stage.

I suggest to start with debug=3 in kamailio cfg and watch the logs when
you do testing calls. Watch also the web browser console/diagnostic
tools to see if you get any hints there.

If you search on the web, you should fine some tutorials about using
kamailio in webrtc -- they might be a good reference to compare with
your config.

Cheers,
Daniel
