System requirements: PBX

Item

Requirement

KPML

The PBX must support KPML for the exchange of DTMF tones between the PBX and the BlackBerry Mobile Voice System.

Support for BlackBerry devices

The device must be an endpoint for the PBX.

SIP line

You must configure a SIP line from the BlackBerry MVS to the PBX so that the PBX can establish calls to devices.

SIP trunk

You must configure a SIP trunk from the BlackBerry MVS to the PBX so that the PBX can send calls to the mobile numbers on devices. When you configure the SIP trunk, you must provide the IP address and port number of the BlackBerry MVS Server.

Call routing patterns for internal numbers and external numbers

The phone numbers that the BlackBerry MVS sends to the PBX might not contain leading digits to indicate how the PBX should route the call. You might need to configure the PBX so that the call routing patterns add or remove leading digits for routing to internal numbers or external numbers. For example, you should consider creating the following call routing patterns:

  • One that permits BlackBerry MVS users to make calls from the call log or contact list on their devices without adding 9 before a phone number
  • One that removes an NDD number from phone numbers that are dialed from devices if the BlackBerry MVS user is in the same geographic location as the PBX. The PBX should be configured to manage calls from devices if the user types (519) 555-0100 or (1) (519) 555-0100.
  • One for regions or countries that your organization's users frequently travel to

Ensure the Class of Service setting of "User may change the mobile phone number" is checked. When your organization's users are roaming internationally, it might be necessary for the users to manually change the mobile number on their devices to reflect what the PBX must dial to contact the user. For example, if the user is from the United Kingdom the mobile number on the user's device should be changed to include the IDD (00), the home country code (44), and the user's area code and local phone number. For more information on changing the mobile phone number on the device, visit www.blackberry.com/support to read article KB17940.

DID/DDI number

To configure BlackBerry device-initiated calling, you must configure your organization's call routing patterns so that the PBX can route the device-initiated calls that use a DID/DDI number to the BlackBerry MVS Server that is associated with the DID/DDI number. For example, if the DID/DDI number that you configure in the MVS Console for the BlackBerry MVS Server is +15195550100, for any device-initiated calls that arrive at the PBX using a DID/DDI number of +15195550100, the PBX must route the calls to the BlackBerry MVS Server that is associated with the DID/DDI number of +15195550100.

You require one DID/DDI number for each BlackBerry MVS Server in your organization’s environment.
