Call Forwarding Frequently Asked Questions

[Alex_Sberna]

How much does Call Forwarding Cost?

Call forwarding is included in the per minute fee, and no additional charges apply. The requirements for enabling it are:

• Your account must be upgraded (trial accounts can only forward calls to verified numbers).
• You must rent at least 1 number from Sinch which you can then use to enable call forwarding from.

Can Call Forwarding be enabled dynamically via API?

Yes, you can configure whatever custom call forwarding functionality you require using the Voice API, such as starting to forward calls after close of business hours.

A great starting point would be learning how to handle an incoming call using the API and follow-up by learning how to use the Sinch Voice Application Markup Language (SVAML), to connect incoming calls.
