I'm attempting to configure several varieties of polycom (SoundPoint IP 550, SoundPoint IP 601) phones to connect to a freeswitch instance using a domain other than default (i.e. the ip address). Everything works wonderfully as long as the domain is named exactly the same thing as the server host provided to the phone (whether that is the server's ip address, or a hostname resolved via dns). As long as those match everything is fine. What I'm trying to sort out is, is it possible to convince the phone to use something other than the server's hostname/ip as the second part of the user name (i.e. user@host)? Or should I just resign myself to making the domain name some host name that can resolve via DNS? I've tried including @somedomain in the authid field of the line of the phone, but freeswitch reports that the user someuser@somedomain@serverip couldn't be authenticated. It appears that the phone always appends the server name... Does anyone know of a way that I configure a polycom to connect as user1@d1 and another to connect as user2@d2 where d1 and d2 are NOT in DNS or are polycoms just going to always use the server host as the @ part of the username?
