Programming Item 150: Flexible Intercom Prefix
5.7.38 PROGRAMMING ITEM 137 : FLEXIBLE PREFIX RANGE START
This item determines the range of the Flexible Prefix Number for directory number and trunk group
access code when Flexible Numbering Plan is enabled.
In a Flexible Numbering Scheme, there have 17 (0 ~ 16) range for flexible prefix.
Range 0 is for intercom. Range 1 to 16 are for accessing trunk group 1 to 16 correspondingly.
If the dialed number is within flexible range 0, system will treat it as intercom call.
If the dialed number within flexible range 1, the dialing extension will access trunk group 1 for outgoing
call.
The flexible range is defined by assigning the first number (Flexible Prefix Range Start) and last number
(Flexible Prefix Range Stop).
Example of using Flexible Numbering Scheme:
Program Setting:
3*133*1
- use flexible numbering scheme
3*134*2*1
- set first digit ‘2’ as the first digit of flexible prefix number
3*136*3
- set flexible prefix number to be 3 digits
3*137*0*237
- set flexible range 0 start at 237
3*138*0*239
- set flexible range 0 stop at 239
3*137*1*210
- set flexible range 1 start at 210
3*138*1*236
- set flexible range 1 stop at 236
3*150*3
- no flexible intercom prefix
Operation:
Dialing 225wxyz will access trunk group 1 and dial wxyz
Dialing 238 will call to directory number 238 (Directory Number Format = 3)
Dialing 250wxyz will hear busy tone, since 250 do not belong to any valid flexible range.
Command
3 * 137 * Index1 * Value <Enter> or
3 * 137 * Index1 * Value * Index2 <Enter>
where Index1 = 0 : intercom
Index1 = 1 ~ 16 : trunk group (1 ~ 16)
Index2 = 0 : intercom <Optional>
Index2 = 1 ~ 16 : trunk group (1 ~ 16)
Value = 0 ~ 9999 : directory number
Example
3 * 137 * 1 * 235 <Enter> - to set flexible range 1 start at 235.
Default Value
Default = 0
