Route Pattern

Last Updated : Aug 06, 2018 |

Use this screen to define route patterns. Each route pattern contains a list of trunk groups that Communication Manager uses to route a call. The maximum number of route patterns and trunk groups allowed depends on the system configuration and the memory available in the system.

Use this screen to convert the dialed number into a format that the network uses for routing the call. For example, you can:

  • Insert or delete digits when Automatic Alternate Routing (AAR) or Automatic Route Selection (ARS) calls route over different trunk groups.

  • Convert an AAR number into an international number.

  • Insert an area code into an AAR number to convert an on-network number to a public network number.

  • Insert the dial access code for an alternative carrier. The system uses this alternative carrier when a call directly accesses a local telephone company central office (CO) and if the long distance carrier that the CO provides is unavailable.

Network regions are added to the Route Pattern form. In the Route Pattern form, you can specify the network region that can be used against each route preference. Network region is applicable for SIP trunks and Off-PBX Telephone Integration and Mobility (OPTIM) end points like EC500 and Telecommuter.

A network region can be populated for each of the route patterns. This network region will be used only when routing SIP trunk calls (SRE Calls) over the route preference (Trunk Group). Network region field on the route pattern applies only for trunk and OPTIM such as EC500 and telecommuter calls but not for SIP station calls. This overrides the network region field on the SIP signaling group for the above mentioned applicable calls.

To modify the value of the fields on the Route Pattern screen, use the following command:

change route-pattern n, where n is the route pattern number.

Band

Inserted Digits

The digits to insert for routing. Communication Manager can send up to 52 digits. This includes up to 36 digits entered here plus up to 18 digits originally dialed. Special symbols count as two digits each.

Valid Entry

Usage

*

When * is in the route pattern and the outgoing trunk is signaling type mf, the MFC tone for the end-of-digits is sent out to the local telephone company central office (CO) in place of the *.

#

When # is in the route pattern and the outgoing trunk is signaling type mf, the MFC tone for the end-of-digits is sent out to the CO in place of the #.

, (comma)

Creates a 1.5 second pause between digits being sent. Do not use as the first character in the string unless absolutely necessary. Misuse can result in some calls, such as Abbreviated Dialing or Last Number Dialed, not completing.

+

Wait for dial tone up to the Off Premises Tone Detection Timer and then send digits or intercept tone depending on system-wide feature administration. The length of waiting time is controlled by the Off-premises Tone Detect Timeout Interval field on the Feature-related system parameters screen.

%

Start End-to-End Signaling.

!

Wait for dial tone without timeout and then send DTMF digits.

&

Wait for ANI that is used for Russian pulse trunks.

p

The associated trunk group must be of type sip. The single digit p is used for fully qualified E.164 numbers. Communication Manager inserts a plus (+) digit to the digit string.

ITC (Information Transfer Capability)

Identifies the type of data transmission or traffic that this routing preference can carry. The ITC applies only to data calls (BCC 1 through 4).

This field must be both or unre for a BCC Value of W.

Valid Entry

Usage

Usage

Valid carrier code

Identifies the carrier for IXC calls.

user

For presubscribed carrier. Used when an IXC is not specified.

none

Must be none for non-ISDN trunk groups and for Telcordia Technologies NI-2 Operator Service Access. If it is necessary to send an IXC code for a non-ISDN trunk group, the IXC code can be entered as Inserted Digits.

Valid Entry

Usage

0 to 28

blank

Inter-Exchange Carrier (IXC) digits are deleted if the field is administered to any non-blank value. If the field is blank, no IXC digits are deleted. Communication Manager administers the IXC digits on the Inter-Exchange Carrier (IXC) Codes screen.

Use for calls that route:

  • To or through a remote server.

  • Over tie trunks to a private network server.

  • Over local telephone company central office (CO) trunks to the serving CO.

No. Dgts Subaddress

Available only if ISDN Feature Plus is enabled for the system.

Valid Entry

Usage

1 to 5

blank

The number of dialed digits to send in the calling party subaddress IE. Allows a caller to reach a number where the media server’s digit processing deletes the dialed number and inserts the listed directory number (LDN). The LDN then is sent to the destination address and the dialed extension is sent in the calling party subaddress information element (IE). At the receiving end, the call terminates to the user indicated by the subaddress number instead of the attendant.

NPA

The three-digit Numbering Plan Area (NPA) or area code for the terminating endpoint of the trunk group. Not required for AAR.

The local telephone company can verify this number. For WATS trunks, the terminating NPA is the same as the home NPA unless the Local Exchange Carrier requires 10 digits for local NPA calls.

Leave blank for AAR calls and for tie trunks.

Pattern Name

An alphanumeric name for the route pattern.

Pattern Number

The route pattern number.

Prefix Mark

Sets the requirements for sending a prefix digit 1, indicating a long-distance call. Prefix Marks apply to 7- or 10-digit Direct Distance Dialing (DDD) public network calls. A prefix digit 1 is sent only when call type is foreign number plan area (FNPA) or home numbering plan area (HNPA) in the ARS Digit Analysis table.

Not required for AAR. ARS requires a number from 0 to 4 or blank.

For a WATS trunk, the Prefix Mark is the same as the local telephone company central office (CO) trunk.

Valid Entry

Usage

0

  • Suppresses a user-dialed prefix digit 1 for 10-digit FNPA calls.

  • Leaves a user-dialed prefix digit 1 for 7-digit HNPA calls.

  • Leaves a prefix digit 1 on 10-digit calls that are not FNPA or HNPA calls.

Should not be used in those areas where all long-distance calls must be dialed as 1+10 digits. Check with the local network provider.

1

Sends a 1 on 10-digit calls, but not on 7-digit calls.

Used for HNPA calls that require a 1 to indicate long-distance calls.

2

Sends a 1 on all 10-digit and 7-digit long-distance calls.

Refers to a Toll Table to define long-distance codes.

3

Sends a 1 on all long-distance calls and keep or insert the NPA (area code) so that all long-distance calls are 10-digit calls. The NPA is inserted when a user dials a prefix digit 1 plus 7 digits.

Refers to a Toll Table to define long-distance codes.

4

Always suppress a user-dialed prefix digit 1.

Used, for example, when ISDN calls route to a server that rejects calls with a prefix digit 1.

blank

For tie trunks.

SCCAN

If enabled, indicates that the route pattern supports incoming SCCAN calls. Available only if Enhanced EC500 is enabled for the system.

Secure SIP

If enabled, specifies using the SIP or SIPS prefix when the call is routed to a SIP trunk preference. If SIP trunks are not specified, the call is routed over whatever trunk is specified.

Service/Feature

An identifier of the Service/Feature carried by the information element (IE) in a call in this route preference. Required by Call-by-Call Service Selection, and Network Call Redirection Transfer. Accepts up to 15 characters.

Note:

User-defined service types for network facilities can also be used. Any user-defined Facility Type of 0 (feature), 1 (service), or 3 (outgoing) is allowed.

Available only if ISDN-PRI or ISDN-BRI Trunks are enabled for the system.
