[Kamailio-Users] fr_inv_timer in kam-3.0

Hi, In the docs at http://kamailio.org/docs/modules/3.0.x/modules/tm.html#fr_inv_timer it says that fr_inv_timer_avp should be defined like this, without $ or $avp: modparam("tm", "fr_inv_timer_avp", "my_fr_inv_timer") In kam <= 1.5 I did it like that: modparam("tm", "fr_inv_timer_avp", "$avp(s:callee_fr_inv_timer)") which doesn't give me an error on startup with kam-3.0 either, but the timer doesn't get fired (I use seconds for that as noted in the docs). If I change it to modparam("tm", "fr_inv_timer_avp", "callee_fr_inv_timer") then I get the error "malformed or non AVP callee_fr_inv_timer AVP definition", same with setting it to "s:callee_fr_inv_timer". Anyhow, it seems to be deprecated anyways, so I'm looking to get t_set_fr() working. I'm just curious how I can use a var or AVP loaded from DB to set the value on-the-fly? t_set_fr(...) seems to allow only constants to be set. Couldn't find anything in the docs regarding that one. Thanks, Andreas
