System requirements: Telephony environment



SIP gateway

The SIP gateway must support the following:

  • ISDN/QSIG signaling or SIP signaling
  • RFC 2833 standards
  • in-band media


Your organization's TDM PBX must support the following:

  • QSIG signaling
  • T1/E1 ISDN-PRI board
  • T1/E1 cross-over cable
  • sufficient licensing for your organization's BlackBerry Mobile Voice System users

Your organization's IP PBX must support the following:

  • sufficient licensing for your organization's BlackBerry Mobile Voice System users

If your organization's telephony environment includes components, such as a voice mail server, that receive DTMF tones from the BlackBerry MVS, the telephony environment must be able to present the DTMF tones in the correct format (for example, RFC 2833, and in-band media).

Caller Identification Number, ANI number (Calling party)

  • When you use PBX-initiated call direction, you must configure a Caller Identification Number for each telephony connector. This number must be unique and dedicated to the BlackBerry MVS. The PBX must use the Caller Identification Number as the calling party number when the PBX calls the device. The BlackBerry MVS Client compares the last six digits of the calling party number with the last six digits of the Caller Identification Number. If they match, the BlackBerry MVS Client treats the call as a BlackBerry MVS call. Ensure that any digit manipulation of the Caller Identification Number preserves the last six digits in the calling party number sent to the device.
  • You can specify additional ANI numbers for identifying BlackBerry MVS calls. Part of the BlackBerry MVS provisioning information that the BlackBerry MVS Server sends to the BlackBerry MVS Client includes the optional ANI numbers so that the BlackBerry MVS Client has a record of the numbers that can call. The BlackBerry MVS Client uses a combination of the caller identification number and the numbers in the Optional ANI numbers list to identify BlackBerry MVS calls.
  • If your organization has a hunt group that is configured in the PBX with multiple outgoing trunks, and each trunk has its own ANI number, you must type each ANI number in the MVS Console.

DID/DDI number (Called party)

  • If you configure your organization's BlackBerry MVS for BlackBerry device–initiated calling, you must configure a DID/DDI number in your organization's telephony environment. This number must be unique and dedicated to the BlackBerry MVS. You configure the DID/DDI number in the MVS Console for each BlackBerry MVS Server. The DID/DDI number is used to provision the user accounts that you configured for the device.
  • In the class of service, make sure that you choose BlackBerry Smartphone > PBX for users that you want to use BlackBerry device–initiated calling. You must verify that a call that arrives at the DID/DDI number prompts the telephony environment to send a SIP invitation to the BlackBerry MVS over the SIP connection that has been configured between the telephony environment and the BlackBerry MVS.

DID/DDI number (No Data Coverage number)

If you configure a no data coverage number, you must configure a corresponding DID/ DDI number on your organization's PBX.

The BlackBerry MVS Client uses the no data coverage number to connect to the MVS Session Manager when the BlackBerry MVS user is in an area with no data coverage.
