Hello, I checked my ser.cfg my table domain in db ser and re-read the documentation of domain module . After reading domain.c file I found a exported function for R-URI which is not is_from_local() for outbound domain but is_uri_host_local(): I add this function in my conf file now i can call others domains however we don't find this function anywhere else that domain.c I use documentation from onsip.org which talk about nat however the examples may be wrong or incomplete.
