[Serusers] invite timer & calls to PSTN

[O'Shaughnessy Evans]

Hello, all.  I have a problem I'm trying to work out:  when a stateful
call goes out from the proxy to the PSTN, the fr_inv_timer will eventually
trigger a failure.  The thing is, I don't want calls going outside my
SIP proxy to have any timer associated with them.  I need it for calls
to local users so they can fall back to voicemail, but I don't need it
for anything else.  E.g. if one of my SIP users calls out to a PSTN
number and, for whatever reason, wants that call to ring 300 times,
the timer in the SIP proxy shouldn't inhibit that ability.

I can get around this by using forward(), but if the SIP user is coming
from a NAT'd device, I have to use a t_relay() instead and then I'm
stuck with the timer running.

Is there a way around this?  Thanks for your help.
