Difficult to say without logs. However, just worth a try: Set the following value to "true" in your sip profile (internal, if config is default). <param name="NDLB-force-rport" value="true|safe"/> http://wiki.freeswitch.org/wiki/Sofia_Configuration_Files#NDLB-force-rport Please reply back if it helped.

Hi All,

I could not make the Panasonic KX-TGP500B04 behind the NAT. I have all the other phones in the same network no issues. Does any one have a working configuration for the FreeSWITCH and Panasonic KX-TGP500B04?

Is something to do with the source port. Panasonic KX-TGP500B04 always say "Registering" but never registered.
