[Kamailio-Devel] extra accounting from replies

[Daniel-Constantin Mierla]

Hello,

you can upload a feature request.

This looks to me like half-hack and has to be reviewed if the contexts 
of request and reply don't get messed up. I was looking for something 
else that fixes also this requirement, but not time to check properly 
the impact to contexts, see next...

I was playing with the idea of more generic approach. While the 
accounting of values from reply can be done now in Kamailio via AVPs (or 
$var(...) in some cases) set in onreply_route plus onreply_avp_mode, and 
of course, some more script lines, in particular cases I needed to 
access reply attributes in failure_route or request attributes in 
onreply_route.

My first thought was to add to TM module two new PV classes:
- $req(PV) to be used in onreply_route to access attributes from the 
request of the transaction
- $rpl(PV) to be used in failure_route to access attributes from the reply

To solve what you pointed, one has to account $rpl(PV), because acc 
event is done on a transaction callback.

PV will be another valid PV name (e.g., $ru, $hdr(...)), but not 
$req(...) or $rpl(...).

Any other opinion about this matter?

Cheers,
Daniel
