The following SIP Portal functions are in support of both SIP Extreme and SIP Gateway services. The portal allows you to configure Call Forwarding and Call Screening features. These features are set up for the entire group of Direct Inward Dialing numbers (DIDs) on the PBX. 

Note: A complete guide to using the SIP Portal is available after logging in to the portal and selecting Help from the User Management drop-down list or by contacting Customer Service.

Call Forwarding

Call forwarding features are set up for an entire group of DIDs on the PBX or an individual DID with the exception of “Unavailable Call Forwarding”. Call forwarding allows you to forward all incoming calls to a single selected number based on a variety of conditions such as:

• Immediately—all calls are immediately forwarded to a user-defined phone number
• Busy/No Answer—calls are forwarded to a user-defined phone number when a line is busy or there is no answer
• Unavailable—calls are forwarded to a user-defined phone number if the PBX / CPE is unavailable
• Selected Callers—calls originating from specific callers are forwarded to a user-defined number

The Forwarding Destinations tab of the portal allows you to create a list of frequently used destination phone numbers.

Call Screening

Call screening allows you to block incoming calls from a specific number.
