[SR-Users] Kamailio and UCARP with Multiple VIPs defined

Hello,

oh, forgot to follow up, as I read your response at some point.

Are you doing force_send_socket() or $fs = ...? If yes, what is the
socket value you are forcing?

The log message said:

Mar  1 20:04:35 bt1proxy1 /usr/sbin/kamailio[20372]: ERROR: <core>
[forward.c:220]: get_out_socket(): no corresponding socket found
for(udp:10.70.0.72:5080)

The socket listen in the rpc command output is udp:10.70.0.75:5060.

Cheers,
Daniel
