Hi,
As far as I remember avp_write (and related config calls) are provided
by the module avpops while the tm parameters are provided by the avp
module.
In fact, and correct please me if I am wrong, the avpops functions
updates the tm modules internally.
In fact, you can also set directly the tm avp using the set_attr config
function (maybe the spelling is not right....check it in the mailing
list/documentation/source code)
Thus, something like:
set_attr ("fr_timer", 14)
t_relay()
would be equivalent to map the inv_timeout avpops "variable" to tm's
parameter fr_inv_timer and set it with avp_write.
Depending on your scenario, you may need to select the timer depending
on some factors (=>use avpops), but if you just want to limit the
duration to PSTN and you have it predefined in your config file, using
just the avp calls is enough.
Hope it helps,
Samuel.

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

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
