Advance Sip Routing
Advance Sip Routing can allow fail-over on main extension based on hang-up cause.
Call forwarding- If the other sip device wants to forward the call to another sip device number, then customer will enable the call forward and select sip device.
No answer- If the other sip device will not answer the call and suppose the no answer field is enabled and forwarded to another extension it will redirect the call there.
On busy- Suppose the customer dials the number which is already on call but it can be routed on another extension if the call is busy somewhere else.
Not registered – In case the number we tried to call is not registered on the destination side and if this feature is enabled then the call will route to that extension.
