I was more or less just curious as to why Freeswith detected all the others at NAT and not those. There isn't any real network topology differences between the endpoints. All are running Polycom firmware v 3.3.1. Thanks, Spencer Aloysius Lloyd <lloyd.aloysius@sunteltech.ca> wrote:
May be the Two phones using different firmware.
Try the following parameter in the extension
<param name="sip-force-contact" value="NDLB-connectile-dysfunction"/>
Thanks Lloyd

Hello all, I'm having a strange NAT problem. My Freeswitch server has a public ip and the endpoints which are Polycom IP 650s are all behind NAT with mainly Netgear SRX 5308 routers at multiple locations. The server is on a public class C network and one of the locations has its router on the same class C. I.e x.x.x.7/24-router, x.x.x.240/24-server. I'm only experiencing this with 2 of about 30 extensions. The first endpoint to register from this location gets detected as NAT but the others with the ports remapped do not. This maybe explains it better:

The port and IP are detected correctly but the contact is a private IP. Any clue as to why the two extension 1101 and 1102 are any different?
Thanks, Spencer
