h1. Call generators

{{>toc}}

h2. Ways of generation

Calls can be generated:
* manually
* automatically with scheduling in specific time

h2. Application schemes 

* [[Telemarketing]]
* [[Provider checking]]

For these schemes there are available pre-configured [[Call generation algorithms]].
Using them, it's easy perform everyday tasks without annoying configuring.

Besides that, you can configure custom [[Call generation algorithms|Call generation algorithm]], which will differ from standard ones.
There you can configure the scheme of generating of outbound call, and which actions will be done, when the callee will pick up.
As least it's easy to configure message playback and IVR.

h2. Theory of operation.

A special background application each second checks [[Call generators]], enabled in web-interface, in which _activation time_ became less than current.
In case if _Timetable_ is specified, it's also checked to make sure that desired conditions for launch has become.

When a _call generator_ with suitable conditions for launch is detected, the application starts generating outbound calls according to configuration of this call generator.

In case if there is configured parallel call generation to several callees, then the system generates outbound calls in parallel, but no more, than _batch call count_ in 1 iteration.
Between iterations the system makes pause with duration _batch pause (sec)_, if specified.

For each outbound call system launches specified _call handler_, which is configured inside [[Call generation algorithms|Call generation algorithm]].

After all calls for a given call generator are generated, the system disables it.
In case if the check-box _delete after processing_ is set, the system will delete the generator.
In case if parameter _repeat ring round in (sec)_ is set - call generation will happen once again after the specified amount of seconds will elapse.

In case if parameter _delete number after pickup_ is set, after picking up the number is deleted from numbers to dial list.
