What firmware and sip versions are you using? I have several Polycom phones on my system right now and I've never had any registration problems with them.
Instead of leaving the host as dynamic try declaring an IP address(that's the only difference I see between your sip.conf and mine). If you are still having problems I've like to see your polycom .cfg files for one of these phones, you might be missing a setting in one of them.

So far it has been good. Call Hold, Transfer, DMTF etc. However, I do notice every now and then the Polycom fails to register with Asterisk. Asterisk console outputs the following: Feb 3 13:02:32 WARNING[278546]: chan_sip.c:2365 __transmit_response: Unable to determine sequence number from '' Feb 3 13:02:34 NOTICE[278546]: chan_sip.c:5125 handle_request: Failed to authenticate user "DavidLiu" <sip:[EMAIL PROTECTED]>;tag=9F67E426-59D92ED7 Feb 3 13:02:36 NOTICE[278546]: chan_sip.c:5125 handle_request: Failed to authenticate user "DavidLiu" <sip:[EMAIL PROTECTED]>;tag=BFDEF35B-1CBC4F2C in sip.conf: canreinvite=yes host=dynamic canreinvite=yes dtmfmode=rfc2833 context=sip port=5060 Usually say after the phone failed to register with Asterisk, I can attempt to place a call. It will fail of course. But then I can try calling again and usually the call will go through and it will successfully re-register itself without needing a restart. What can this be? Surely Polycom is re-registering every 3600 before Asterisk times it out. But Asterisk is just refusing it. By the way, anyone know whether Asterisk is geared towards RFC3261 or RFC2543? I know Asterisk is not a fully SIP Proxy but lets say if a SIP PSTNGW or a SIP phone is designed under the spec 2543 as suppose to 3261, will it work better or the same with Asterisk?
