Hi,

Our sofia stack is running on a server with 2 IP addresses configured on 
the same network interface 172.28.2.95 (eth0) and 168.10.10.1(eth0:1) 
but is only bound to 172.28.2.95.

When we respond to an incoming call the "o" field in the SDP is always 
set to the lowest IP address that is available on the server. Even when 
we explicitly set the sdp origin address to 172.28.2.95 it still gets 
replaced by the lower IP address when we call nua_respond.

Why is sofia replacing the o address from 172.28.2.95 that we set in the 
nua_respond with the 168.10.10.1 address?

Many Thanks for your help.
