[Serusers] 305 Use Proxy

[Rick van Rein]

Hello,

I am trying to setup a redirecting proxy server with Ser, but I find that
my GXP-2020 phone gets into an endless loop.  Is this common?

The phone is configured to use my ser service which is set as a proxy.
If it tries to dial things that this proxy shouldn't handle, it sends
back a "305 Use Proxy" response.  The phone seems to ignore the proxy
and tries again.

1) Is it common for the proxy redirection not to work?  I've seen it being
   ill-advised on iptel.org because the RFC isn't too clear how it works.

2) What would be the proper formula to get Ser to send back a proxy
   redirect?  I may be approaching it wrongly, but I cannot find much
   documentation about it online.


Thanks,
