Sota Solutions Posted April 9, 2008 Report Share Posted April 9, 2008 Has anyone had any experience of setting up phones behind a CISCO PIX. We have 2 x SNOM phones at a customer location, behind a CISCO PIX firewall, registering to a hosted PBX. The SNOM phones are registering successfully, however in the phone log the phones register every 1800 seconds instead of the usual 15 secs on working phones. 9/4/2008 09:56:46: Registered at registrar as email@example.com (Expires: 1800 secs) This is typical where the phone is behind a device with a SIP ALG, and usually disabling the SIP ALG solves this. We have tried the following command on the PIX no ip nat service sip but continue to have problems with incoming calls. So if anyone has any experience/suggestions they would be gratefully recieved!
