Abbreviated Dialing 175

This feature is implemented with a pre-translation group assigned to every

telephone. All IP Phones in the same bandwidth management zone use the

same pre-translation group. TDM telephones, which share the same dialing

plan with IP Phones in a bandwidth management zone, also use the same

pre-translation group. The pre-translation group assignment is more easily

and quickly done using the TM 3.01 global change functionality.

Table17 "Sample values for Abbreviated Dialing" (page 175) gives some

sample values to help explain the functionality of AbbreviatedDialing.

Using the sample values from Table17 "Sample values for Abbreviated

Dialing" (page 175), Abbreviated Dialing works as follows:

•An IP Phone or TDM telephone in the main ofﬁce can call another

telephone in the main ofﬁce by dialing only the last four digits of the

called party’s DN (for example, "3000" to reach "703000").

•An MG 1000B IP Phone, in Normal or Local Mode, or a TDM telephone

in the Branch Ofﬁce can call another telephone in the Branch Ofﬁce by

dialing only the last four digits of the called party’s DN (for example,

"3000" to reach "713000").

•An IP Phone or TDM telephone in the main ofﬁce can call a telephone

in the Branch Ofﬁce by dialing all six digits of the called party’s DN (for

example, "713000").

•An MG 1000B IP Phone, in Normal or Local Mode, or a TDM telephone

in the Branch Ofﬁce can call a telephone in the main ofﬁce by dialing all

six digits of the called party’s DN (for example, "703000").

•An incoming call to a main ofﬁce telephone has a four-digit DN, such as

"3000." The main ofﬁce location code (in this example, "70") is added to

the front of the DN, and the call terminates as indicated by the full-length

DN (in this case, "703000").

•An incoming call to an MG 1000B telephone has a four-digit DN, such

as "3000". The Branch Ofﬁce location code (in this example, "71")

is added to the front of the DN, and the call terminates as indicated

by the full-length DN, in this case "713000". In Local Mode, the call is

terminated locally. In Normal Mode, the call is routed to the main ofﬁce

using VNR.
