Cisco BTS 10200 Softswitch-Based Features

Call Forwarding Activation and Deactivation

Activation and deactivation of call forwarding features uses the star code. Alternately, the feature may be activated or deactivated by using the Services key on certain phones.

With SIP support, the call forwarded to number can be a Centrex extension number (only applicable for business users) or an E.164 number.

Note Forwarding to a URL (AOR) is not supported in Release 4.4.

SIP subscribers do not hear a final dial tone upon completing activation or deactivation. Instead, an announcement plays for the subscriber, indicating that the status of the forwarding feature is being activated or deactivated. This is irrespective of the Final Stage Dial Tone (FDT) flag (Y/N) provisioned for these features.

Call Forwarding to an E.164 Number or an Extension Number

In Release 4.4, activation is accomplished using single-stage dialing. This applies to all activation and deactivation.

Calling Name and Number Delivery

Calling number delivery (CND) provides the SIP subscriber endpoint with the date, time, and calling number in an incoming call. When the called subscriber line is on hook, the calling party information is delivered during the long silent interval of the first ringing cycle. Telcordia document GR-30-CORE specifies the generic requirements for transmitting asynchronous voice band data to the SIP subscriber line.

Rules

The rules associated with populating the calling party number in the outgoing INVITE from the Cisco BTS 10200 to the terminating SIP phone are as follows:

•If the calling number is available, and the presentation indication is not restricted, the number is populated into the user information portion of the From: header. Otherwise, this user information field is empty.

•If the calling number is available, and the presentation indication is restricted, the display name field of the From:header is set as ‘Anonymous.’ Otherwise, the following logic is used to populate the name display field of the From: header:

–If the calling name exists and the calling name presentation indication is not restricted, then the calling name is populated into the display name field of the From: header. Otherwise, the display name field in the From: header is left empty.

Calling Number Delivery Blocking (CNDB) controls whether the caller’s DN is delivered to the called party. CNDB is supported on a call-by-call basis, by dialing a privacy feature code or by using the feature key to prevent the subscriber’s DN from being delivered on the next call.
