Multi-Site Customer with ISP Included in SLC¶
The Intersite Prefix (ISP) is included as the first digit of the site code. Currently, VOSS-4-UC does not support the ISP as a separate component for the Directory Number construction. Without ISP in the DN, a CTI application such as Corporate Directory feature has problems; the DN returned from the Corporate Directory must be manually manipulated before a call can be placed. To work around this issue, Cisco recommends that the ISP be included as the first digit of a Site Location Code (SLC).
