[SR-Users] strange acc behavior?

[Klaus Darilion]

Hi!

I use acc module with extra accounting.

modparam("acc", "db_extra", "direction=$avp(direction)")

I set $avp(direction) during request processing (in main request route).

The value stored with INVITE and BYE is fine, but ACK requests do not 
have the assigned value, but the same value as the INVITE request.

Is this by design? Is this a limitation of tm and AVPs?

Thanks
Klaus
