Hi,
we figured out that the problem is in 1.4.2. In "master", there have
been implemented several fixes and enhancements for using multiple IPs.
So it is highly recommended to use the latest master for such SBC
deployments.
Thanks,

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

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.
