Hi,

I will look into that, thanks for the report.

Thanks, Bogdan--great feature in 1.11.x I was originally looking in the 1.8.x man pages.

I just got 1.11.2 working here in dev and the feature works great. One question--any reason that if I xlog the $T_fr_timeout or $T_fr_inv_timeout variables they return 0 whenever they were not explicitly set in the script instead of returning the default values that were set in the mod_param section for tm module?

In any case keep up the good work!

Hi,

fr_timeout is the interval between the request and the first provisional reply - shortly, how long to to wait for the first provisional reply.

fr_inv_timeout is the interval between the request and the final reply (2xx or negative) - shortly, how long to wait for completing the transaction.

So you can use different values for these 2 timers for a transaction to get the desired behavior.

Hi,

 From the TM module man page it would see fr_timeout should fire whenever a 
final reply is not received for a request but it is only limited to ACK's for 
negative INVITE replies? Is this correct?  Can someone be so kind as to clarify 
when fr_timeout is triggered.

Is there a method to set a timeout between specific provisional replies in an 
INVITE?  In other words let's say we receive a 100 TRYING but then see a very 
long delay until the next provisional reply (specifically 183 Ringing).  Is 
there a way to timeout the request so that we can route advance to another 
gateway?

We have a carrier who is randomly prone to lengthy PDD intervals in completing 
calls we send to them.  On such a call our initial INVITE almost immediately 
sees the 100 Trying but then we might see another 25-30 seconds before we 
seeing another provisional response such as 183 Ringing or a final response.

Is there a way to implement an INVITE specific provisional response timer so 
that if we get the 100 Trying and then don't see any other provisional response 
in a much shorter period of time (for example no more than 6 seconds) we could 
then route advance and attempt the call on another gateway.  Is this at all 
possible?  Serial forking to the next gateway would be fine but parallel 
forking would be preferred after the provisional timeout occurred.  We'd just 
not want to route advance if we received the 183 Ringing provisional response.

Any help or insight would be greatly appreciated.

Cheers,

JPS
