[SR-Users] IPv4, IPv6, RTPProxy and Kamailio

[Mark Zeman]

Hello all,

The subject says most of it, I think.

We set up our Kamailio and RTPProxy according to
http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6
with the addition of an alias (siplab.ch), and the DNS to go with it, as
well as TLS and SRTP.

However, we only get working calls IPv4-IPv4 and IPv6-IPv6! IPv4-IPv6 we
get a proper connection,
secured with SRTP, but no audio. Looking at the network, RTP packets go
from the caller to the server,
but nothing leaves the server and no RTP packets go from callee to server.

Do you have any idea how to fix this?

Cheers,
Mark
