Summary:                    Some hanging ReceiveFAX app after a dax y with 1000
Fax
Description: 
I have an asterisk 1.8beta2 to receive fax with ReceiveFAX. After every
working day after i received about 1000 fax, i have 1-3 hanging ReceiveFAX.
They just do nothing, there is no UDPTL traffic any more. I can hangup them
with the hangup cmd.

The questions is, how can i debug what happend to them? And perhaps we
need also a "udptltimeout" option like the rtptimeout option to prevent
this.

---------------------------------------------------------------------- 
i was able to see, that this happen, after asterisk send out the T.38
re-INVITE, get a "100 Trying" (from the SIP proxy that i in between) but
never get a answer then to the T.38 re-INVITE. And then asterisk/ReceiveFAX
send an endless RTP stream out, an never hang up.

I try to help myself with rtptimeout and SIP timeout. And i dont now if
this behave is a ReceiveFAX  bug. Or just a special situation, which
rtptimeout and SIP timeout therefor are.
