Hi Guys,

I’ve been experimenting with originate_timeout and progress_timeout as follows…

However, shouldn’t the timeout trigger a 408 Request Timeout instead of 480 Temporary Failure if no Provisional response received?
Just curious, it seems to make sense to me.. but maybe SIP gods see differently.

I have also tried using ${originate_disposition} after both bridge attempts to fetch the timeout disposition
but instead this is set to NO_ANSWER (which would be correct for first attempt)
As I understand it originate_disposition is reset for each bridge completed either successfully or unsuccessfully.
Shouldn’t the second attempt with no 100 Trying ever received trigger a NO_USER_REPONSE on timeout?
According to RFC 4497 that would map to 408 Request Timeout

For this test
(please note progress_timeout set to low “2” value to test timeout)
Node 10.200.1.11 is setup in such a way it responds with 100 Trying but never reaches 180 or 183 before 2 sec timer expires (as desired for this test)
Node 10.200.1.12 (is disconnected and never even sends a provisional response, as desired)

I have tried…

As well as …

</condition>

Any thoughts, am I completely nuts and missing something in the spec?
