Call Routing Management

View Call Routing Table Entries

At the directory tree, select Telephony > Call Routing Tables to view the Call Routing Tables screen.

Add Call Routing Table Entries

Insert a new line in the Call Routing Tables screen, then double-click on the new line to present the Edit Call Routing Tables dialog box

Modify Call Routing Table Entries

Double-click on an entry in the Call Routing Tables screen, to present the Edit Call Routing Table Entries dialog box.

ID

Value to define number of the Call route

Desc

Text string that describes the call route

Enable Load Balancing

Select the checkbox to enable Load Balancing.

Enabled

Click on the checkbox to enable the routing table. Leaving the checkbox unchecked disables the route.

Using Regular Expressions

Select this check box to use regular expressions for number matching in addition to the proprietary system used by VX.

Description

Enter an optional text description.

Priority

The priority assigned to this table. Priorities may be assigned from  0 - 255 (0 having the highest priority; 255 having the lowest priority). In the table, all matching entries are selected based on the top down search; the entries are then ordered based on the Priority setting.

Expression Helper

Launches a dialog to demonstrate and help build regular expressions.

Advanced SIP Matching

Normally, the @address part of SIP URIs is not included for the purpose of matching. Checking this box means, for this route, the entire URI will be tested, not just the name.

MLPP Namespace

If not Any , specifies this rule matches only a particular namespace.

MLPP Precedence

If not Any , specifies this rules matches the specified precedence or higher.

Input To Match

User provided pattern or regular expression to match.

Match Rule

The pattern or regular expression to match against called number.

Match Using AD Field

Specifies which AD field to use to match.

Match Exact Length

Used mostly when wildcards are in use.

Numbering Type

The input numbering type.
Select appropriate entry from dropdown dialog box.

Numbering Plan

The input numbering plan
Select appropriate entry from dropdown dialog box.
0-Unknown
1-ISDN
2-Data
3-Telex
4-National
5-Private
6-Telephony

Carrier Select Info

Select a carrier type from the dropdown dialog box.

Carrier Code

Available when the carrier type is selected.

Input Number

The pattern to match the called number against
When the called number is matched to the rule it will follow the output rule.

Translate to Output

MLPP Precedence

If not Untranslated , the precedence of the call is changed to match this.

Translate Rule

Specifies the pattern or regular expression that the called number will be translated to.

Translate Using AD Field

Select an AD field from the dropdown list.

Numbering Type

The output numbering type
The numbering type that the phone number will be sent with in the setup message. Select appropriate entry from dropdown dialog box.

Numbering Plan

The output numbering plan
The type of trunk that number is going to. The OutNumPlan ensures that the format will be correct. Select appropriate entry from dropdown dialog box.
0-Unknown
1-ISDN
2-Data
3-Telex
4-National
5-Private
6-Telephony

Carrier Select Info

Specifies the SS7 carrier select mode to be used

Carrier Code

When the carrier select info is set to UserInput, this value can be populated e.g. 1010220

Circuit Code

Specifies the SS7 circuit code to be used

On Match Parameters

Signal Diffserv

Set the DiffServ packet priority to this value.

Media Class

Select a media class from the drop-down list.
The media class selection determines what codecs are allowed for this call. It also determines the preference order for codec selection. Note that codec selection applies to all calls, even if no codec would ultimately be involved (such as a TDM-TDM call). The media class is selected on the call route, the inbound trunkgroup, and outbound trunkgroup for this call. The allowed codecs are the intersection between all three of these.

• Call route has the highest dominance for codec preference order
• Outbound trunkgroup has the second highest
• Inbound trunkgroup has the least

  Exception for Redundant RTP Payload

  
  When the RTP Payload Redundancy (RED) option is enabled in a Media Class applied to a Trunk Group, the VX system always add the RED payload (97) in SDP of INVITE.
  
  
  
  
  
  
  

Transfer Cap

Select a transfer capability from the dropdown list.

OutCircuit Code

Select an outcircuit code value.

Media Diffserv

Set the DiffServ packet priority to this value.

CallingTransTable

The calling number translation table to be used for this call.,

Msg Xlat Table

The message translation table to be applied
Message translation provides a mechanics for translating incoming messages into outbound messages.

Jitter Optimization

The jitter optimization field lets you set the jitter buffer behavior
The range is 0-12. The higher the setting the more aggressively the jitter buffer will shrink to accommodate packet delivery latency. Insufficient jitter buffer size causes gaps in the voice audio reception. For best IVR performance set to 0.

Jitter Min Delay

The minimum size that the jitter buffer can shrink to
The smaller the jitter buffer, the more likely that latency will cause audio reception gaps.

Mirror Media Diffserv from Inbound Media

Applicable for outbound calls ONLY.
Check the box to enable the DSCP to be mirrored.  If disabled, the DSCP will not be mirrored.

Destination

Remote destination for calls using this route
For BSP, this value contains the remote NodeID. For SIP, this value contains the SIP proxy IP address or domain name (or can be left blank for no proxy). Call Route Table is used by AD to set up call routes in Microsoft OCS environments.
Note: This value is not used by TDM. (TDM channels inherently have only one hardwired destination.)
When Deny is selected, all calls which match the route will be rejected.

SIP Registrar Table

Select this radio button to use the local SIP Registrar table to route this call
The outgoing Trunkgroup will be chosen based on which Trunkgroup the SIP Phone is registered to.
Note: Use the show registrar-table command in the CLI to see the list of currently registered SIP Phones.
If a trunk group is selected you also need to provide a SIP Proxy.
Select N/A for the trunk group if no SIP Proxy is to be provided.

Node ID/SIP Proxy

FQDN or IP Address of the Proxy that should be used for this route

Trunk Group

The ID of the trunk group for outgoing calls on this route

VTP Interface

BSP only--Identifies the IP interface to use for VTP traffic

BSP/SIP Link Requirements

Used in conjuction with Peers, Link Requirements define the network conditions which must be met for this call route to be an available destination.
Works for both BSP and SIP peers

Min Quality

This setting only applies to destinations that are on another node
The setting indicates to the system the expected quality of the link. By comparing this value to the actual packets passing through the system can determine if the link can be selected. This facility is used in conjunction with the Ping Limit in determining the quality of a link.

Ping Limit

Minimum Ping latency set in milliseconds.

MLPP Requirements

MLPP Namespace

Used to map calls to and from VX priority numbering. Valid values are:

• Disabled 0
• Transparent 1
• Unset 2
• DSN 3
• DRSN 4
• Q735 5

MLPP Precedence

Lists the priority this call has relative to all other calls. Valid values are 0-31.

MLPP New Outbound Precedence

Select untranslated to pass the current MLPP priority through
If a different MLPP precedence is required, selecting it from this list will change the outgoing call precedence level to the selected value
