We use it to override the default timer value when we forward calls to other systems, so as to give a longer timeout on a call forward (which means we don't time out too early while negotiating the transfer). Our default is 27 seconds (roughly 5 US-style phone rings), but we bump it with the AVP to 45 when doing a forward. Works like a charm.
I'd LIKE, however, to be able to have it overridden on an individual user basis for people who'd prefer it going to voicemail quicker... or slower. I'll give Klaus' idea a go and let you know how it all works out.

I didn't know that the timer was variable? I thought it could only be a static setting...that is, you can't have different timer values for different dialogs. Has that changed?

This should work:
modparam("tm", "fr_inv_timer_avp", "i:678")
avp_db_load("$to","i:678");

Try loading it directly into the fr_inv_timer_avp.

I still don't see it. I could, perhaps, understand that maybe avp_copy would be what I want, to copy the value I've retrieved from the avp_db_load into the inv_timeout avp, but I'm not using OpenSER, and the version of AVPOps that comes with SER 0.9.6 doesn't include an avp_copy (nor, honestly, am I convinced that would be the correct approach). avp_pushto won't work, as its destination can't be an AVP.
avp_write won't work as it's limited to $ruri, $from, IPs, headers, and static values as its destination... again, no AVPs. So... is there a way without avp_copy to write an avp to an avp? N.

This is possible for sure. Reading the AVPOPS tutorial should help you: http://www.voice-system.ro/docs/avpops/0.9.0/

Can anyone think of a way, perhaps using AVPs, perhaps using a custom module, that I might do something like set fr_inv_timer_avp on the fly to a value pulled from the database? I was looking at the AVP commands, and I couldn't figure out a way of grabbing a number of seconds from the DB (that part's easy enough), storing it into an AVP, and then storing the value from that AVP into fr_inv_timer_avp. Now, storing statically is easy enough... at the top of my ser.cfg, I have:
modparam("tm", "fr_inv_timer_avp", "inv_timeout")
And off inside the cfg, I've got:
avp_write("i:45","inv_timeout");
... to write a static number of 45 seconds to the inv_timeout. That works. I'm just trying to think of a way to make it dynamic, storing a value for that number of seconds in the DB, and retrieving it on a per-user basis (so each user could set his individual timeout values should he so desire). Maybe I'm just not thinking about this correctly. Anyone have a direction I could try?
