We just started experiencing a problem with call transfers. This use
to work but we cannot figure out what broke. We are investigating our
gateway software but I wanted to check with the SER community too. If we
receive a REFER method we simply t_relay(). Is this the correct handling ?
Thanks,Steve

REFER should be handled as the OPTIONS message, which can be received
inside and outside a dialog, i.e. you need to be able to handle it with
Route (and thus loose route it with t_relay) as well as handle it as an
INVITE by rewriting the r-uri.

Take a look the Refer-To header. This will be evaluated by the other
party. If the other party is a gateway it must have route for the
destination. This is often a problem if the users use a different dial
plan than the gateways (e.g. user dial 00431... and the gateway uses 431...)
If this is the problem you can use textops to rewrite the Refer-To header.
Further you should also screen the Refer-By header for bad destinations
- e.g. 0900 number ... because must phones accept a REFER without asking
the user (permissions module)
