Multi-Site Customer with ISP Included in SLC
--------------------------------------------

The Intersite Prefix (ISP) is included as the first digit of the site
code. Currently, VOSS Automate 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).
