Call Flow

Definition

Call Flow is set of rules how call should behave when it is trying to reach some device.

It can be reached by pressing on Call Flow link in device details:

Call has several states which are visible from this image:

• Before Call - call has not reached device
• Call – call to device is in progress
• Answered – call was answered
• No Answer – call was not answered and ended after timeout
• Busy – callee was busy
• Failed – call to device failed

Actions

We can take actions for several call states: Before Call, No Answer, Busy and Failed.

The possible actions are:

• Empty
• Forward
• Voicemail
• Fax detect (only for Before Call state)

Empty

Empty – means no action should be taken. It is default in most cases.

Forward

Call can be forwarded to Local device or External number:

System owner (admin) can select any device he likes. If user is editing his devices Call Flow – he can select only his devices.

Using forward function it is easy to implement:

• Unconditional forward – when forward is used in Before Call state
• Forward on no answer/busy/failed – when forward is used in No Answer, Busy or Failed states
