Hi,
I am trying to setup the SBC module on two public ips (one added via
sip_ip , and another via additional_interfaces in sems.conf, also added
as outbound interface in corresponding sbc.profile) but the 100 trying
reply from sems got the wrong ip in the contact header? I noticed debug
messages about computing outbound interfaces but it still makes no sense
for me because with the main ip (sip_ip setting in sems.conf) it seems
to be fine, while the other has the wrong contact (the ip from the first
interface..)?
WARNING: Error while computing outbound interface: default interface
will be used instead.
everything fine when sending to the main IP e.g. sip_ip setting :
U 2012/02/07 12:59:59.061226 109.21.11.11:5060 -> X.X.X.X:52104

Call to the additonal_interface/second ip, which has the ip of the first
interface as contact instead of the signaling ip which was used:

Is there anything wrong about my setup? I tried all possible
combinations of additional ips / interfaces but i never got it to work
correctly when using two public IPs, or more detailed the
"additional_interfaces" ip never got the right IP in the contact header.
Maybe i am just doing it wrong?
Best Regards
Max M.
