Hi,
I have in my ser.cfg:
modparam("tm","fr_inv_timer",40)
set as a timer so that INVITEs coming from PSTN callers go to voicemail after 40 seconds. This works great for inbound called, however it seems to be a limitation for outbound calls. If the outbound INVITE doesn't receive an ACK in that time period, the call gets cancelled and drops to fast busy.
Is there a way around this? Can I set different timers for inbound and outbound calls? 40 seconds seems to be a good amount time so that most outbound calls get answered by voicemail or actual people, but occastionally users will still get a fast busy.
Any advice is greatly appreciated.
Dan
Depends upon the version. I'm using 0.8.14 stable. In there the answer is no or not really. You can build another proxy and use one for inbound and one for outbound calling. This way the same timer can have different values thereby producing different results for inbound and outbound calls.
I understand some people have had success on this issue with avp_ops module in 0.9.0 but I have yet to address this issue in that release.

That's correct, in 0.9.0 you can set different timer values on per transaction basis. TM module would pick the value for the timers from AVPs, see fr_timer_avp and fr_inv_timer_avp parameters of tm module.
The AVPs can be loaded using avp or avpsops modules.
Note that there is a performance inpact when this feature is used, but in real world setups it does not seem to harm.

I am finally at the point where I am trying this with 0.9.0 and I have just a couple of questions.
Jan, you state that tm will "pick up" the timers from AVP. I've seached the list and find references to fr_inv_timer_avp that look like this:
modparam("tm", "fr_timer", 15) modparam("tm", "fr_inv_timer", 22) modparam("tm", "wt_timer", 5) modparam("tm", "fr_inv_timer_avp", "inv_timeout")
I'm just a little unsure as to how this is supposed to be called (there is nothing about avp in the tm/README). When I use he above config I don't see any mysql queries to the usr_preferences table that would indicate where I might store a timer AVP.
Do I need to avp_db_load("$from","s:inv_timeout") or something or should tm grab this on its own? Ultimately I'd like to have timers that can be set up on a per user basis.
Thank you for your time.
Dan

Dan,
You can set the timer with something like this:
avp_write("i:45", "inv_timeout"); # set invite timer to 45 seconds
Just do this before you t_relay()
I use this to give extra time when dialing SIP->PSTN since many PSTN phones (like cellular phones) need the extra time.
Regards, Paul
