IP Phone calls

When an IP Phone calls another IP Phone, each telephone receives the

address of the other to exchange media directly between the telephones.

Also note that when in Normal Mode, an MG 1000B IP Phone calling a main

ofﬁce IP Phone does not require any trunking to setup the call. However,

LAN/WAN bandwidth is used to providea media path for the call. For more

information on Direct IP media path functionality, see IP PeerNetworking

Installation and Commissioning (NN43001-313) .

Zones A zone is a collection of IP Phones that:

•share similar IP bandwidth restrictions

•are geographically close to one another

•are all in the same time zone

•are all in the same PSTN dialing plan

For dialing plan purposes, all telephones in the same zone are treated

identically. Each IP Phone is assigned to a zone during conﬁguration.

IP Phones at a Branch Ofﬁce are conﬁgured withina unique zone. In the

main ofﬁce Call Server, IP Phones at the Branch Ofﬁce are assigned to a

Branch Ofﬁce zone to deﬁne the numbering plan for local, long-distance

(optional), and emergency services calls. Zone conﬁguration modiﬁes the

dialed digits so a local, long-distance (optional) or emergency services

call can be sent to a NRS as a long-distance call. Zone conﬁguration data

enables the main ofﬁce Call Server to modify the dialed digits for these types

of calls initiated from an MG 1000B telephone. The NRS then provides the

endpoint information to route the call to the Branch Ofﬁce.

ATTENTION

Throughout this document, the term "zone" is deﬁned as a Bandwidth

Management Zone, not a Gatekeeper Zone. Refer to "Bandwidth Management"

(page 55).

Vacant Number Routing

VacantNumber Routing (VNR) is mandatory in a Branch Ofﬁce. If a vacant

number is dialed, the number is not treated as invalid,and the call is routed

to the Gatekeeper. The Gatekeeper tries to determine where the terminal

is located. If the terminal is located, the call is routed to the terminating

location. If the terminal cannot be located, each of the alternate routes will

be tried, in the conﬁgured sequence. If all alternate routes fail, the call is

blocked.
