Best practice: Preparing your environment

When you prepare your environment to support the BlackBerry Mobile Voice System, consider the following guidelines:

  • Verify that you can send individual DID/DDIs out of your telephony environment and through the PSTN trunks. The BlackBerry MVS uses at least one DID/DDI that you assign to the telephony environment as the Calling Line ID for BlackBerry MVS calls. The BlackBerry MVS Client uses the DID/DDI to identify calls. You should not replace this number with a main listed number or a billing number.
  • You should route calls around other components that are in call flows, such as other gateways, PBXs, or Session Border Controllers, to maintain the proper communication between the BlackBerry MVS Server, BlackBerry MVS Client, and PBX.
  • Verify whether any of the following features are used in your environment. These features are supported on a best-effort basis.
    • Call recording
    • Call Accounting or Authentication Codes
  • Ensure that the BlackBerry MVS supports your organization's PBX. The following are the supported PBXs:
    • Cisco Unified Communications Manager 6.1, 7.0, 7.1.x, 8.0, 8.0.1, 8.0.2, 8.0.3, 8.5, and 8.5.1
    • Mitel Communications Director 4.2
    • Nortel Networks Communication Server 1000 5.x (requires an Mediant 1000 or 2000 SIP gateway)
    • Avaya Aura Communication Manager 5.2.1, 6.0, 6.0.1 (requires an Mediant 1000 or 2000 SIP gateway)
  • Ensure that your dial plan contains only numeric characters in extensions or directory numbers. If your extensions contain any non-numeric characters, the BlackBerry MVS will not work.

  • The BlackBerry MVS requires PRIs or SIP trunks. For other types of trunks support is on a best effort basis.
  • Ensure that BlackBerry MVS calls are not routed through a Cisco 6608 gateways. The Cisco 6608 gateway does not support KPML signaling which the BlackBerry MVS requires.
  • Ensure that any Cisco gateways are upgraded to a minimum IOS of 12.4.24T to ensure proper processing of DTMF signals.
  • Ensure that you can assign MTP resources to your Cisco Unified Communications Manager configuration. For some types of call flows, hardware MTP resources are required to ensure proper call setup.
  • Ensure that you have a computer or a virtual computer available to install the BlackBerry MVS software on.
  • Ensure that neither the PBX nor BlackBerry Enterprise Solution is hosted in a cloud. The component must be installed on premises to meet the port and network latency requirements of the BlackBerry MVS.
  • Confirm that the response times between the following sets of components are less than 240 milliseconds:
    • BlackBerry MVS Server to PBX or media gateway
    • BlackBerry MVS Server to BlackBerry Configuration Database
    • BlackBerry MVS Server to BlackBerry Enterprise Server
