Applies to VoipNow 3 and higher!

Probably most of you have already dealt with a busy tone while making a call. This article describes what you should very in case a busy tone occurs either when placing a call or receiving one from/to an extension. This applies to both external and internal calls.

Step-by-step guide

To explain exactly how this works, we have used the following scenario:

0003*001 (DID 4444) is called Extension A, 0003*002 (DID 5555) is called Extension B, 0005*002 (DID 6666) is called Extension C and 9999 is called D.

Extensions A and Extension B belong to the same Organization whereas Extension C belongs to a different Organization, D is a public number that does not belong to the VoipNow system. Note that you can make calls between extensions on the same client by using the long format (e.g. 0003*001) or by using the DID (e.g. 4444).
