Item Requirement
• 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

DID/DDI number To 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.
