[Freeswitch-users] FreeSWITCH and Panasonic KX-TGP500B04 Cordless

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. Thanks Lloyd
