[Freeswitch-users] Problem with Polycom

[Abaci]

We have OpenSIPS in front of FreeSWITCH, phones register to OpenSIPS, 
OpenSIPS sends all calls to FreeSWITCH. the way we have it set up is 
that both OpenSIPS and FreeSWITCH auth all the invites (we have it like 
this for a reason). this setup works fine (with Yealink  at least).

Problem we have is with Polycom phones, the phone registers just fine 
but can't make calls. When OpenSIPS gets the INVITE it responds with a 
407, to which the Polycom responds, OpenSIPS is then sending the call to 
FreeSWITCH which sends a 407 again, OpenSIPS proxies it back to the 
polycom, however the Polycom does not respond to the challenge.

I don't think this is a FreeSWITCH problem, I would still like to hear 
if anyone has an idea how I can get this working (config option?)

Thanks
