394 Appendix C On-net dialing plan configuration examples
• The MG 1000B Core terminates the incoming Virtual Trunk call to DN
3101.
• The Voice Gateway channel in the Branch Office provides IP-TDM
transcoding.
From main office to Branch Office using UDP-LOC
In this scenario, the following occurs:
• DN 3001 or 3002 dials a number "65043101".
• The main office Call Server recognizes the digit "6" as AC1. The Call
Server accesses the RLI appropriate for the LOC "504" and uses the
Virtual Trunk specified for that route.
• The NRS is queried for a destination node IP address with which to
route the call over the Virtual Trunk. For "ESN 504 3101", the Branch
Office node IP address is returned since "504" is registered to the
Branch Office.
• The MG 1000B Core terminates the incoming Virtual Trunk call to DN
3101 because "504" matches the HLOC of the Branch Office.
• The Voice Gateway channel in the Branch Office provides IP-TDM
transcoding.
From Branch Office to main office using CDP
In this scenario, the following occurs:
• DN 3101 dials a number "3001"(or "3002").
• The MG 1000B Call Server recognizes the number as a vacant number.
Because VNR is enabled, it uses the Virtual Trunk specified for that
route according to the RLI defined for VNR.
• The NRS is queried for a destination node IP address with which to
route the call over the Virtual Trunk. The main office IP address is
returned because "30" is registered to the main office.
• The main office Call Server routes the incoming Virtual Trunk call to
DN 3001 (or 3002).
• The Voice Gateway channel in the Branch Office provides IP-TDM
transcoding.
From Branch Office to main office using UDP-LOC
In this scenario, the following occurs:
• DN 3101 dials a number "65013001"(or "65013002").
• The MG 1000B Core recognizes the first digit "6" as AC1. The MG
1000B Core accesses the RLI appropriate for LOC "501" and uses the
Virtual Trunk specified for that route.
