Figure 2. Call Agent Rulesets

EXT_DIGIT_LENGTH=5

The length of the internal numbers is set to 5, for numbers like 22100 - 22199.

PATTERN=221[0-9][0-9

The pattern for the internal range of numbers would be 22100 - 22199.

Calls to this number range stay always local (would not be sent to the PSTN in survival mode).

DOMAIN=192.168.17.44

The IP-address of the MX-ONE in this case 192.168.17.44.

APP_PREFIX=SCA- and APP_PREFIX=EDN-

This is the prefix for the usernames connected with shared appearance and extra directory number (EDN). In this example, you have two user names: SCA- and EDN-

PATTERN=221[0-9][0-9]

This defines the local numbers, in this example the internal range would be 22100 - 22199.

A_PRFX=031325

This is the prefix for the local numbers used on outgoing calls to the PSTN. In this example, you can add a number block 031325 in front of the number specified in PATTERN-parameter to form a valid calling party number to be sent to the PSTN.

PSTN_PREFIX=00

This parameter specifies the prefix to break out to the PSTN. When a user dials this number (in survivable mode) it will be truncated.

This ruleset applies to calls to numbers defined in BNUMBER and will add B_PRFX to the called party number.

This ruleset must be repeated for every approved destination (that is, calling the HQ and other branch offices).

Calling HQ:

BNUMBER=67[0-9][0-9][0-9]

Applies to calls to the specific range of extensions. The pattern for the internal range of numbers would be 67000 - 67999.

B_PRFX=08568

This is the prefix for the Called Party Number. In this case, it will be built like: National Prefix (08) + Main part of the HQ's local number: (568).

Calling BO#1:

BNUMBER=111[0-9][0-9]

Applies to calls to the specific range of extensions. The pattern for the internal range of numbers would be 11100 - 11199.

B_PRFX=013443

This is the prefix for the Called Party Number. In this case it will be built like: National Prefix (013) + Main part of the HQ's local number: (443).

Calling BO#3:

BNUMBER=321[0-9][0-9] Applies to calls to the specific range of extensions. The pattern for the internal range of numbers, in this example the internal range would be 32100 - 32199.

B_PRFX=040598

This is the prefix for the Called Party Number. In this case it will be built like: National Prefix (040) + Main part of the HQ's local number: (598).

Calling BO#4:

BNUMBER=421[0-9][0-9]

Applies to calls to the specific range of extensions. The pattern for the internal range of numbers, in this example the internal range would be 42100 - 42199.

B_PRFX=036618

This is the prefix for the Called Party Number. In this case it will be built like: National Prefix (036) + Main part of the HQ's local number: (618).

This ruleset applies to calls to numbers defined in BNUMBER and will use the BOVERRIDE as Called Party Number.

One use case could be if a user dials the internal operator (09) while in survivable mode. The dialled number (09) will be replaced with 0856867000 which could be the number to the operator in the HQ.

BNUMBER=09

The internal number to the operator.

BOVERRIDE=0856867000

Calls to extensions like BNUMBER will be sent to BOVERRIDE. In this example, it will be sent to 0856867000.

(Builds the registration cache for survivability purpose).

EXT_DIGIT_LENGTH=5

The length of the internal numbers is set to 5, for numbers like 22100 - 22199.
