Hi,

I can't reproduce this, neither the empty IP address nor the segfault. Can you tell me which version exactly of both mediaproxy-ng and the rtpproxy-ng module you're using (downloaded from where, which repository, which branch), as well as the entire log for a particular call, i.e. everything from the initial offer to the final delete.

cheers

And rtpproxy-ng segment fault when I hangup call.

Hi,

the "x"-Parameter in dlg_manage is for bridging IPv4/IPv6. You only
have configured one address, so the x-Parameter does not make any
sense here.
http://kamailio.org/docs/modules/devel/modules/rtpproxy.html#idp2994536

Kind regards from the implementor of the "x"-Parameter,
Carsten
