Dialing plan examples

65

For calls that tandem over the Virtual Trunk to the branch office and go
out to the PSTN trunk(s) in the branch office, the following configuration
problems can occur:

The call can receive overflow tones. Use L D 96 to view the digits sent
to the Virtual Trunk (ENL MSGO {dch#}).

If the digits look correct at the main office, the NRS might not be
properly configured. If the NRS rejects the call, a diagnostic message
is displayed on the Signaling Server console.

If the call makes it to the correct branch office (check that it is not going
to the wrong node if the NRS is configured incorrectly) the branch office
is probably rejecting it because it does not know the digit string. Use
LD 96 to view the digits (ENL MSGI {dch#}).

Dialing plan examples

This section describes the following dialing plans:

Coordinated Dialing Plan (CDP)

Uniform Dialing Plan (UDP)

Coordinated Dialing Plan

The following section provides three options for creating a CDP dialing
configuration.

Overview

Dialing plans between the SRG and the main office need to be coordinated
to ensure seamless dialing between the systems. The option you choose will
determine how the user dials the other system or the SRG IP telephones.

Option 1: DN ranges in the main office and SRG are unique, and DNs
for SRG IP Phones are the same in both Normal and Local mode. This
is the recommended configuration to support seamless dialing on both
systems. See

"Option 1" (page 70)

.

Option 2: DN ranges in the main office and SRG overlap, and DNs for
SRG IP Phones are the same in both Normal and Local mode. See

"Option 2" (page 75)

.

Option 3: DN of SRG IP Phones and DN in the main office overlap in
Normal Mode, but are unique in Local Mode. See

"Option 3" (page 81)

.

Call scenarios

Call scenarios fall into the following categories:

Common call scenarios occur in all CDP calls, regardless of which
option is used.

Unique call scenarios occur only within certain CDP options.
