IMG 1010 - Presentation Number Interworking - BT

Feature F-5626 Support for Presentation Number adds the Presentation Number into the IAM message. The value of the Presentation Number is derived from the Generic Number in one of the following SIP headers:

• Remote Party ID (RPID)

• P-Asserted Identity

• Routing Number

For the feature to function correctly, a new variant (British Telecom), which is automatically loaded into the Variant folder (/opt/dialogic/common/config/Variant) during installation, needs to be imported to the signaling variants object within ClientView. When configured correctly, this feature adds the following three parameters to the IAM message.

Below is Configuration information describing how to configure the IMG to utilize the new Variant.
