Chapter 48 Setting up VoIP trunks for fallback 431

BCM 4.0 Networking Configuration Guide

To assign a VoIP line pool

1 Click the route you created for the VoIP lines.

2 In the Use Pool field, type the letter of the line pool for the VoIP lines.

3 Leave the External Number field blank unless the destination digit you are using for the

remote gateway is different than the number you want to use for the destination code.

4 In the DN Type box, choose Private.

Go to the next section: “Adding the destination code for the fallback route” on page 431.

Adding the destination code for the fallback route

Create a destination code that includes the VoIP and PSTN routes that you created in “Adding

routes for fallback” on page 430 to respond to the same access number (destination code). When

this code is dialed, the BCM will select the VoIP line, if possible. If the line is not available, the

call will fall back to the PSTN line.

As well, you need to create, or ensure, that your destination code 9 includes a Normal and VoIP

schedule that includes the route you created to the local PSTN.

To create destination codes for your fallback route

1 Select Configuration > Telephony > Dialing Plan > Routing, and then select the Routes tab.

2 Click Add.

The Add Route dialog box appears.

3 Enter one or more digits for this destination code.

4 Click OK to close the dialog box.

Example:

Destination code digit: If it is available, you might want to use the same number that you used for

the destination code of the gateway.

If you have multiple gateways, you could use a unique first number followed by the destination

digits, to provide some consistency, such as 82, 83, 84, 85 to reach gateways with destinations

digits of 2, 3, 4 and 5.

The number you choose will also depend on the type of dialing plan the network is using.

Networks with CDP dialing plans have unique system codes. However, with networks using UDP,

this is not always the case, therefore, you need to be careful with the routing to ensure that the

codes you choose are unique to the route. This will also affect the number of digits that have to be

added or absorbed. It is helpful to use the Programming Records to plan network routing so you

can determine if there will be any conflicts with the destination codes you want to use.

Note: If you already have a line pool access code defined as 9, you will need to

delete this record before you create the destination code.
