network. The
branch prefix of each B5800
Branch Gateway system
must be unique and must not
overlap. For example 85, 861
and 862 are okay, but 86 and
861 overlap. On calls routed
via an Avaya Aura
®
Session
Manager line, the branch
prefix is added to the caller's
extension number.
Beginning in B5800 Branch
Gateway R6.2, you have the
option to leave the Branch
Prefix field blank. If you do
not configure the Branch
Prefix, the native extensions
must be defined with the full
enterprise number.
Local Number Length Range = Blank (Off) or 3 to 9
for native extensions
This field sets the default
length for extension numbers
for extensions, users, and
hunt groups added to the
B5800 Branch Gateway
configuration. Entry of an
extension number of a
different length will cause an
error warning by Manager.
The combined Branch
Prefix and Local Number
Length should not exceed
15 digits.
Beginning in B5800 Branch
Gateway R6.2, you have the
option to leave the Local
Number Length field blank.
