Hi,

I am using kamailio as outbound proxy integrated with rtpproxy.I have done the configuration of ipv6 to ipv4 network.

But when 183 session progress came ,kamailio is sending its ipv6 address to pjsip client inside sdp body.So that it is not accepting and 488 error message is giving.

How to convert ipv6 to ipv4 inside kamailio so that pjsip can accept.

Below is the sip trace from client.
