[Devel] Dialog module export-avp request

[Dimo]

Hi guys,
It was nice seeing and talking to you on the conference. As discussed
with Bogdan I am sending this e-mail with a request for a dialog
module feature.

Is it possible to add to the roadmap an implementation of an avp
exported by the dialog module which can hold the start time of the
current call?
The idea is on BYE to be able to access what the call start was (OK
200) for the call for which BYE message is being processed.
In this way RADIUS accounting for call end can be done sending both
start and stop time with extra accounting parameters and having the
billing server calculate the duration of the call by only looking at
the accounting stop.

Best,
Dimo
