System requirements: PBX

•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 numberTo configure 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 MVS Session Manager that is associated with the DID/ DDI number. For example, if the DID/DDI number that you configure in the MVS Console for the MVS Session Manager 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 MVS Session Manager that is associated with the DID/ DDI number of +15195550100.

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