Yes, but the nat is handled by the Sonicwall, which works perfectly for the Polycom desk phones. It is only the Bria softphones that are behaving strangely. I think it is just caused by them attempting to use rport, which is sort of doing to work of the Sonicwall twice, causing them to lose sync with the FreeSWITCH registration. I just wanted the opinion of some other professionals if this sound likely, before I consider the matter resolved.
