If you want to divert all incoming calls for a standalone extension, you can set this up in Advanced section of the extension configuration page.
Firstly, login to your VoIP control panel and click on the Extensions quick link.
In the Extensions section of your control panel, click the configure (cog) icon to the right-hand side of the extension that you wish to setup the call divert for and select Configure Extension and click on the Advanced tab.
A call can be diverted to an external number (which will be charged), a local seven-digit extension or a SIP URL.
To configure your divert, switch the Divert unanswered calls to another number? option to Yes.
The Divert Time field is used to control after how long, in seconds, the call is diverted, and you can also control the divert behaviour using the Divert Mode field.
- Sequential: this is like a 'standard' divert. The SIP phone is called, and if it either fails (offline, busy, etc.) OR is not answered within the divert delay, the call is cancelled and the divert number is called instead
- Delayed parallel: this type of divert works by calling the SIP phone in parallel with a delayed divert. In other words, the SIP phone will ring, and after the specified delay, your divert number will be called, and your SIP phone will keep ringing. If the SIP phone is offline or unavailable, the caller will hear silence until the delay period has elapsed
- Sequential with repeat: this is a hybrid of the above methods. It is the same as sequential, but after the SIP phone either times out or fails, the divert AND the SIP phone again will be called in parallel. This does however mean that two separate calls are placed to the SIP phone - so if for example the customers misses the call and picks it up on their divert number, the SIP phone will register two missed calls instead of one.
Finally, enter the number or SIP address in the Where should calls divert to? and click Save Settings.
