You might try entering your external NAT IP into the Polycom config. I've found that if you specify the external IP, Polycom's generally work better thru NAT. This is one area where Cisco is superior to Polycom. On Cisco, you just enable NAT and you don't have to specify the external IP. Of course Cisco has a whole mess of their own issues too.

This is because the Polycom doesn't support STUN, RPORT or any other nat traversal technology. You have a couple of choices please review http://wiki.freeswitch.org/wiki/NAT_Traversal
Also review the NDLB-force-rport option for the sofia profile to assume rport. CAUTION this breaks things like cisco phones.

hi, I use FS server at public Address. I use polycom's IP550 at private address(192.168.0.120), Now there is a problem that the IP550 can not register to FS. But when I use account to eyebeam, the registering is OK. the attachment is my IP 550's config file, I think it must be NAT problem. Can anyone can help me solve it?
