Main Office Configuration for Survivable Remote Gateway 50 Configuration Guide
The calls must be routed according to the branch office ESN
configuration.
2 From an SRG IP Phone in Normal Mode:
a. Make a call to the local PSTN.
b. Make a long-distance call.
The calls must be routed according to the ESN configuration that was
configured in Procedure 11 on page 175.
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#}).

Overview
Dialing plans between the SRG and the main office need to be coordinated to
ensure seamless dialing between the systems. The following section provides
three options for creating a CDP dialing configuration. The option you choose
will determine how the user dials the other system or the SRG IP telephones.
