Coordinated Dialing Plan 385
From Branch Office to main office In this scenario, the following occurs:
•
DN 3101 (in the Branch Office) dials DN 3001 (or 3002 - both are
registered with the main office).
•
The Branch Office recognizes 3001 as a vacant number. Since VNR is
enabled, the call is routed using the RLI defined for VNR, using the
Virtual Trunk specified for that route.
•
The NRS is queried for the destination node IP address with which to
route the call over the Virtual Trunk. Because "30" is registered to the
main office, the main office node IP address is returned.
•
The main office Call Server ter minates the incoming Virtual Trunk call to
DN 3001 (or 3002).
•
The Voice Gateway channel in the Branch Office provides IP-TDM
transcoding.
When the Branch User telephone is in Local Mode In this scenario,
the following occurs:
•
The MG 1000B Core handles the call processing of DN 3002.
•
If no network outage or Signaling Server/NRS failure occurs, DN 3002
can call any telephone in the Branch Office and main office.
•
However, DN 3002 cannot be reached from the main office by using
CDP, because the DN is not registered at the main office as it would
be in Normal Mode.
