Hi List, after reading the corebook in the wiki and some issue reports (1), I think it's not possible to force the outgoing ip for uac.so registration.
I saw traffic with 172.20.120.53:45689 - - - > reg.sip-trunk.telekom.de So that's random highport generated traffic tcp traffic on the first interface ip. AFAIK this behavior could not change, right?
