Figure 4-7. Gateway Number Screen
On this screen, you can configure the following options:
❑
Gateway Number Type
• Direct Inward Dial (DID) : DID allows a caller outside a
company to call an internal extension without having to go
through an operator. When using DID, the number of digits
in the DID is that portion of the full DID that the Gateway
will be given from the ISDN service provider as the Called
Party Line Identifier. This, in turn, will be passed to the
Gatekeeper for address resolution. The endpoint needs to
register this portion of the DID as an E.164 alias with the
Gatekeeper in order for this to work.
• Number + Extension : If enabled, this option allows the call
to go through directly (it dials the Gateway number + ## +
Extension as one number).
