Intra-Site Extension Dialing¶
Within a site, users can make calls to other users by dialing only the extension part of the directory number. Although the lines are provisioned as (ISP)+SLC+Extension number, when the user dials only a subset of these digits, the dial plan treats the call as an intra-site call, and prefixes the called number with the ISP+SLC to route the call.
Note
Intra-site calls can also be dialed as ISP+SLC+Extension.
