You neglected to indicate what type of firewall(s). Local to the server firewall is important as is the remote firewall.
There are *typically* only 2 things that would make this happen (with Polycom phones anyway): 1 - DNS. Sounds like you have phones inside / outside. In this instance you must have split DNS setup ( http://wiki.sipfoundry.org/display/sipXecs/DNS+Concepts+for+sipXecs - see scenario 1 near bottom of page). 2 - Firewall Connection Timeout. The firewall may be terminating the port 5060 session... and thus registrations will fail. If using netgear, run away from them, their ALG (Application Layer Gateway) sucks and can't seem to turn it off. If SIP 'Helper' or alg is enabled in any firewalls, disable it. SIP 'Helper' = SIP Breaker. Mike On Mon, Sep 17, 2012 at 5:10 AM, Tony Graziano <[email protected] > wrote: > Check the proxy and registrar logs. Also check CPU and ram/swap.
