Well I found out the fix and it was a combination of a few things. SIP ALG was enabled SPI was enabled along with DoS prevention and block anonymous request. I turned off all the settings and it was still happening but what I found out is that SPI scans UDP traffic and UDP traffic will loose packets if there's something in it's path. once I changed to TCP ONLY as my protocol for the phones the problem went away.
I still have very short registration times but it re-registers over itself and does not have an expired registration anymore.

Compare the 'expires' time returned from the sipXregistrar (as seen in the logs or on the wire between sipXecs and the pfsense) to what the phone receives. It may be that the pfsense is artificially shortening the registration as a NAT keepalive mechanism (some systems do this - sipXecs does not). _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
