[SR-Users] rtpproxy-ng ipv4-ipv6 bridge mode problem

[Pavel Miskov]

Hi all,

I'm trying to use rtpproxy-ng module (kamailio 4.1 from GIT) and
mediaproxy-ng (from https://github.com/sipwise/mediaproxy-ng) in
bridge ipv4-ipv6 mode with new NG protocol but keep getting "Failed to
extract streams from SDP: No address info found for stream" (log is
bellow).

Same setup, same SIP clients, same network but with old rtpproxy
module and mediaproxy-ng without NG protocol works fine for ipv4-ipv6
bridge mode. of course, only change is in Kamailio configuration where
now I load rtpproxy module and change sockets not to use new NG
protocol. mediaproxy-ng configuration is untouched.


Best regards

/Pavel
