[SR-Users] Multihomed Setup - Missrouted ACK and not rewritten SDP Packet

Tue Apr 3 10:18:58 CEST 2012

Hi all,

missing or missrouted ACKs are often to read on the mailinglist. But i
didnt found my issue there.

1.) After the 200 ok SDP the proxy gots an ACK from the UAC. But its
not send to the IVR, kamailio
send it back to the UAC (with the wrong source ip).

2.) The outgoing SDP packets contains RFC1918 (private) addresses.

How can i fix that issues? mhomed=1 is set.

Thanks!
