[Serusers] Dynamic Invite Timer w/AVPOPS

[Marian Dumitru]

Hi Laurent,

Yes, you can do so. Unfortunately the "fr_inv_timer_avp" parameter 
doesn't supports AVP aliases, but only raw names - not even IDs :-(.
So, do something like this:

modparam("tm", "fr_inv_timer_avp", "inv_timeout")

...
avp_db_load("$ruri", "inv_timeout/forwardingDB")
...


Since the TM expects for "fr_inv_timer_avp" an string name AVP with 
string value, you have to set type=0 in AVP database (see 
http://www.voice-system.ro/docs/avpops/ar01s04.html for more details).

I would take the opportunity to ask if it wouldn't be better to use 
number values for this AVPs ("fr_inv_timer_avp" and "fr_timer_avp") 
instead of strings - it will save a lot of extra conversions.

Best regards,
Marian
