The SIP Soft Switch can automatically forward calls under specific conditions, and modify the destination number of a call before forwarding the call.
The voice application may disable call forwarding on a per call basis. For example, if an extension belongs to a Contact Center agent and the Contact Center routes the queued call to the agent, the call forwarding for this extension will be disabled to avoid routing queued calls to the agent's voice mail.
•To configure how the SIP Soft Switch forwards calls to an extension, access the Forwarding tab for that extension.
•To configure how the SIP Soft Switch forwards calls to a user, access the Forwarding tab for that user’s code.
To Configure the Forwarding Tab Settings:
- On the Management Portal menu window, click System Configuration > SIP Soft Switch>Phones.
- On the Regular Phone page, click the extension link, then click the Forwarding tab.
- You can configure the phone to modify the destination number under one or more of the following circumstances:
•Unconditional Forwarding - The phone modifies the destination number for all calls.
•Forward on No Answer (timeout) - The call destination does not answer within the time limit you specify in the No answer timeout field. The time limit you specify cannot exceed 120 seconds. The default is 40 seconds.
•Forward on Busy - The call destination is busy.
A network might use ringbacks, which are ring tones the caller hears while the network tries to connect the call. If the phone is busy, several seconds may pass before the caller actually hears the busy signal.
•Forward if Unreachable (Phone is Off or Not Registered) - Either the call destination does not provide at least a provisional response within the time limit specified in the No response timeout field (the default is 4 seconds) or the call destination does not have an IP address registered with the SIP Soft Switch (immediate forward).
- For each circumstance listed in step 3, configure the following:
•Strip, # of Digits - The number of digits the SIP Soft Switch removes automatically from the beginning of the telephone numbers of forwarded calls. This feature is useful for stripping a 9 from a telephone number before sending a call to a gateway. The default value is 0, meaning the SIP Soft Switch does not remove any digits.
•Prefix with these digits - The digits the SIP Soft Switch prefixes automatically to the beginning of the telephone numbers of forwarded calls. This feature is useful for adding a mandatory prefix such as 011 to international calls. The default value is empty, meaning the SIP Soft Switch does not add any numbers to the beginning of the numbers dialed from this phone. The SIP Soft Switch disables this feature if you do not specify the digits to prefix.
Click the Update button on the tab to apply your changes.
