Command Usage
Specify unique phone group site
prefix
digits
for routing VoIP calls.
Syntax Options
Remarks
The example in this command for the string portion of the syntax sets the site prefix digits to
be used to
81
. This means that from any channel on the network, whenever the digits
81
are
pressed, a certain number of digits is expected to follow. If the site prefix is set to
81
, and the
format is
xxx
to get to extension
306
, for instance, the caller would dial
81306
to get to exten-
sion
306
from anywhere in the VoIP network. In this case, a two digit dialing prefix is used,
so the VoIP network can support 999 sites, with
100
extensions per site.
A prefix is an indicator consisting of one or more digits allowing selection of different types
of number formats (e.g., local, national or international), transit networks, and/or the service.
Prefixes are part of the number and are signaled over internetwork or international bound-
aries. When prefixes are used, the user or automatic calling equipment always enters them.
Prefixes are used on the source voice switching daughtercard, and are sent to the remote end
destination. H.323 gatekeepers receive prefixes as part of the alias name.
If the phone group dialing type is either NANP extensions or International extensions, then
the first digit of the site prefix digit cannot be the same as the first digit of the extension, as
specified via the
phone group numbers to include in range of digits
command.
