Dear RonR,
Any other thoughts? Voice Services -> SPx Service -> X_UserAgentPort isn't it. This can be set to anything and if I set the ITSP Profile A -> Sip -> SIP Proxy Server Port to 5060 it works, if it's anything else does not work.
Maybe I need to call Obihai.
YH, I can get the obi working with 5060 so your link is not very helpful. Maybe it's something with astersk 1.4, but considering that it works with the pap2 on port 5010, I just don't understand why the Obi doesn't work.
