Branch Office dialing plan
Since IP Phone users can be located at a Branch Office equipped with an MG 1000B Core, the
routing of calls to the local gateway is important (especially when toll charges apply to calls made
from the central Call Server that controls the telephone). The administrator can configure digit
manipulation through zone attributes for IP Phones to select a main office or Branch Office that
provides PSTN access local to the destination of the call.
The Branch Office feature supports the various PSTN interfaces. Refer to Avaya Electronic
Switched Network: Signaling and Transmission Guidelines, NN43001-280 for further information.
Calls from the PSTN to users within the network can be routed with the various ESN numbering plan
configurations or the Vacant Number Routing (VNR) feature. This enables small sites, such as a
Branch Office, to require minimal configuration to route calls through other Call Servers or through
the NRS.
Outgoing calls can include local and, optionally, long-distance calls.
To access local PSTN resources, outgoing calls can be routed using ESN as well as zone
parameters that enable digit insertion. The zone parameters force calls made by a Branch User to
be routed to the desired local PSTN facilities.
For more information about PSTN configuration, see
the Branch Office on page 76.
Avaya recommends that the Branch User ID (BUID) be the same at the Branch Office as the DN at
the main office. A BUID has a maximum of 15 digits. Under the recommended Coordinated Dialing
Plan (CDP), it can be an extension (for example, 4567). Under the Uniform Dialing Plan (UDP), it is
the user's main office DN, the Location Code (LOC), plus the Access Code (for example, 6
343-5555).
The main office DN must be an ESN-compliant DN. See
