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#}).
Coordinated Dialing Plan (CDP)
Uniform Dialing Plan (UDP)
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
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
Common call scenarios occur in all CDP calls, regardless of which
option is used.
