Hi,

I do not exactly understood how callback leg is billed. From my point of view there should be separate rating plans which will be used in order to separately bill callback call and user dialled number, of course after user hang up callback system must sum those two amounts.

As well there should be separate choice of carriers. Usually for callback everybody uses carrier with has better route quality which allows system to recognize DTMF tones and after user pick up callback and dialled number,cheapest carrier will be preferable.

Can it be implemented in next versions?

Thanks,

the All-callback option might already provide what you are looking for.

With all-callback you have to specify which tariff to use to make the callback. therefore you will be able to specify a rate and a trunk for the call ... hence you could define a specific carrier and rates for your callback service

Unfortunately you will not be able to use the callerid to authorize

as to billing and how it is shown: both legs are billed and shown separately they are not combined but if memory serves me right there is a tag in the CDR that clearly shows it as a "callback".

IMHO this is the prefered way to do it because when you try to match up [reconcile] calls you want to see and show all the calls you don't wnat to have any combination. just my opinion so don't get bent out of shape .

BTW a2billing can handle calls priced as "0.0" so if you don't want to charge for the callback this option allows you to rate the callback as 0.0 but still show it.

give it a try. let us know how it works
