Exchange access authorization
The outgoing authorization to telephone into the public network is defined with
the parameter
Exchange access
in a permission set. The permission set is then as-
signed to a user.
This setting does not bar dialling into the public network with abbreviated dialling
and emergency numbers (see
"Bypassing the digit barring", page 165
).
Note:
If the call type for hotel applications is configured to
Room
,
Exchange
access
can also be set in the user settings. To enable a hotel guest to make
external calls,
Exchange access
must be allowed in the assigned permis-
sion set as well as in the user settings.

Priority exchange allocation
This feature gives individual users preferential treatment when they set up outgo-
ing connections. If a user with priority exchange allocation sets up a connection
and all the B channels of the selected route to the network are busy, one of the B
channels will be cleared down and made available to the user (user configuration
setting:
External priority
=
emergency
).

local exchange interfaces, not across the entire network.
