Hi List I have been pondering over a problem to use an asterisk server behind an SBC unable to successfully handle registrations.
Now I observed something strange which I suspect might be a bug on the asterisk side. The SBC originates is register from Port 6011 to Port 5060 on the Asterisk. The Contact Header of the REGISTER contains: Contact: user@SBC-IP:6011 The Asterisk is sending the 200 OK to back from it's port 5060 to SBC-IP:6011 nothing wrong with it. But when I looked at the Contact Header, which indicates a successful 'binding' I see: Contact: user@ASTERISK-IP:6011 It looks like the SBC discards this Contact header as invalid and returning the 200 OK without contact to the registering client, indicating an unsuccessful registration. All other clients I have tried registering directly to asterisk seem to ignore this port and just accept the 200OK. Only our SBC causes this problem. I have attempted rewrite_contact yes and no, both with the same result. So from my point of view, Asterisk is putting the 'remote' port instead of it's own SIP port into the Contact Header. Can anyone confirm this is misbehavior be pjsip? Could this be a known bug? A quick google search did not return any hits.
