[OpenSIPS-Users] INVITE with unknown udp port number

[Bogdan-Andrei Iancu]

Hi Yagishita,

If different than 5060 (default) the port is required in SIP. BTW, the 
call to UA2 is done via lookup(location) ?  if so, check via the 
"opensipsctl ul show UA2_AOR" the contacts the UA2 has registered with 
opensips.

Regards,
Bogdan
