Configuring for device-initiated call direction (DNIS Callback)

For BlackBerry Mobile Voice System calls, setup of the media path between the Cisco Unified Communications Manager and the BlackBerry device can be initiated by the Cisco Unified Communications Manager (PBX-initiated call direction) or by the BlackBerry MVS Client (device-initiated call direction) (for more information, refer to the call direction sections earlier in this guide).

For device-initiated call direction, the BlackBerry MVS Client dials a DID/DDI number that terminates at the Cisco Unified Communications Manager gateway. The Cisco Unified Communications Manager must be configured to route the incoming call to the MVS Session Manager. To achieve this, you need to configure a Route Pattern, Route Group, and Route List for each DID/DDI number.

Configure a route group

A route group allows you to prioritize a list of gateways and ports for outgoing trunk selection. You must configure a new route group that contains the SIP trunks that serve the BlackBerry Mobile Voice System.

Suggested setting

Settings for your organization's PBX

Route Group Name

This field specifies a name that defines what the route group is used for (for example, use RG_MVS_UCM for the Cisco Unified Communications Manager route group).

Available Devices

Specify the SIP trunks that you created for the BlackBerry MVS. One SIP trunk is required for each telephony connector+MVS Session Manager pair.

Configure a route list and route list details

Route lists are composed of route groups, and route groups are composed of gateways and trunks. Route lists and route groups permit you to control which gateways or trunks send outgoing calls. You must create a route list for calls from the Cisco Unified Communications Manager to the BlackBerry Mobile Voice System. You must also set several route list details for the route list.

For the route list:

Name

This field specifies a name that defines what the route list is used for (for example, use RL_MVS_UCM).

Cisco Unified Communications Group

Select the group that you created to store the Cisco Unified Communications Manager server information (for example, CMG_MVS).

Selected Groups

Select the route group that you created for the BlackBerry MVS (for example, use RG_MVS_UCM).

For route list details, in the Called Party Transformations section:

Configure a route pattern

A route pattern contains a string of digits and a set of associated digit manipulations that send calls to a route list or a gateway. The route patterns work in conjunction with route lists to direct calls to specific devices and to include, exclude, or modify specific digit patterns. A route pattern is required to send incoming BlackBerry device-initiated calls from BlackBerry MVS Client instances to the MVS Session Manager.

Settings for your organization's PBX

Route Pattern

This field specifies the digit pattern that matches the pattern that the Cisco Unified Communications Manager receives from the PSTN gateway for the BlackBerry Mobile Voice System DID/DDI number for BlackBerry smartphone-initiated calling .

For example, if the DID/DDI number for BlackBerry smartphone-initiated calling is +14165551234 and the PSTN service provider sends the last four digits only, then the Route Pattern is 1234.

Route Partition

Select a partition that is contained in the calling search space that is assigned to your PSTN gateways.

Gateway/Route List

Select the route list that you created for the BlackBerry MVS (for example, RL_MVS_UCM).

Called Party Transform Mask

The number you specify here is the full E.164 number entered for the BlackBerry MVS DID/DDI number for BlackBerry smartphone-initiated calling element, but without the plus sign (+) (for example, 14165551234).
