System requirements: Telephony environment
Item Requirement
DTMF Your organization's telephony environment must be able to perform the following
actions:
• detect and intercept DTMF tones from the cellular call leg between the PBX and
BlackBerry® devices
• notify the BlackBerry MVS Server of the DTMF tones using KPML notification
• emit DTMF tones into the audio path when the BlackBerry® Mobile Voice System
requests them
• send DTMF tones that are at least 100 milliseconds in duration to devices
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, in-band media, H.323).
ANI number (Calling party) • The Calling Line ID of a received call identifies the BlackBerry MVS call that is
presented to the device. The Calling Line ID must be configured in the MVS
Console to match the ANI that your organization's telephony environment plans
to use for all BlackBerry MVS calls.
• Any BlackBerry MVS calls that a device makes must use the ANI that you
configured in your organization's telephony environment so that the called party
can see the caller ID that is configured for the BlackBerry MVS user.
• 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. You configure the DID/DDI number in the MVS Console
for each MVS Session Manager. The DID/DDI number is used to provision the
user accounts that you configured for the device.
Planning Guide System requirements: Telephony environment
5

Item Requirement
• 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 telephony
connector that has been configured between the telephony environment and
the BlackBerry MVS.
voice mail server (if
necessary)
If your organization uses solicited voice mail, the BlackBerry MVS requires a SIP line
to your organization's voice mail server, which must be compliant with RFC 3842, so
that a MWI displays on users' devices.
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.
G.729 is supported by BlackBerry MVS 5.0 and later. It is supported on all devices
except for the BlackBerry® Bold™ 9000 device and devices that operate on CDMA
networks.
SIP line The BlackBerry MVS requires a SIP line be connected to the PBX so that the PBX
can establish calls to devices.
If you configure the BlackBerry MVS for high availability, you must configure a
SIP line on each MVS Session Manager.
SIP trunk The BlackBerry MVS requires that a SIP trunk be connected 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 MVS
Session Manager.
If you configure the BlackBerry MVS for high availability, you must configure a
SIP trunk on each MVS Session Manager.
call routing patterns for internal
numbers and external numbers
The phone numbers that the BlackBerry MVS sends to the PBX are E.164
formatted numbers and 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
Planning Guide System requirements: PBX
6

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 [phone] or (1) [phone].
• 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 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 [phone], for any device-initiated
calls that arrive at the PBX using a DID/DDI number of [phone], the PBX
must route the calls to the MVS Session Manager that is associated with the DID/
DDI number of [phone].
You require one DID/DDI number for each MVS Session Manager in your
organization’s environment.

Planning your organization's Wi-Fi
infrastructure
3
If your organization plans to use Wi-Fi® enabled BlackBerry® devices for making and taking BlackBerry® Mobile Voice
System calls, you must make sure that your Wi-Fi infrastructure can support Voice over Wi-Fi calls. During the planning
process, you should collaborate with your organization's Wi-Fi infrastructure vendor to make sure that the Wi-Fi
infrastructure is designed and configured to support Voice over Wi-Fi calls.
To make sure that your organization's Wi-Fi infrastructure can support Voice over Wi-Fi calls, you should use
BlackBerry devices to perform an in-depth site survey. For more information, visit www.blackberry.com/support to
read article KB13299. The results of the survey should permit you to perform the following tasks:
• design and configure a Wi-Fi controller-based architecture
• identify the type of authentication and level of encryption that your organization requires
• configure a QoS implementation
• determine the expected Wi-Fi coverage and capacity boundaries of the access points
• determine the capacity of your organization's Wi-Fi infrastructure. Make sure that you account for the expected
usage for both BlackBerry MVS users and individuals who use Wi-Fi technology on their laptop computers.
• create documentation for your organization's users to help them configure their devices to connect to Wi-Fi
networks and make Voice over Wi-Fi calls
Best practice: Planning your organization's Wi-Fi
infrastructure
The following guidelines are intended to help you design a Wi-Fi infrastructure that permits BlackBerry devices to
connect to an access point that has a medium-to-high data rate. When the data rate of the access point is too low
or the signal strength of the access point is too weak, the device should roam to an access point with a higher data
rate or a stronger signal strength. When designing your organization's Wi-Fi infrastructure, you should consider the
following guidelines:
• Establish a minimum signal strength level of -65 dBm in the planned coverage area.
• Establish a minimum SNR of 25 dB in the planned coverage area.
• When roaming in the planned coverage area, make sure that it takes no longer than 50 milliseconds to perform
an access point to access point handoff.
• Eliminate any 802.11b-only devices and the associated data rates. By eliminating the 802.11b-only devices,
802.11g devices do not need to enter protection mode, which reduces the maximum data throughput of the
devices.
Using Wi-Fi enabled BlackBerry devices for making and taking BlackBerry MVS calls from a home office or a hotspot
is unpredictable because of the instability of those types of networks and cannot be expected to be as reliable as
when the user is in a controlled environment. If your organization's users make Voice over Wi-Fi calls from a home
office or hotspot, you must make sure that the integrated VPN client on their BlackBerry devices is configured for a
highly secure connection to your organization's network through the Internet.

Planning a BlackBerry MVS installation 4
You can install the MVS Console and MVS Session Manager on the computer that hosts the BlackBerry® Enterprise
Server or on a separate computer. During the first BlackBerry® Mobile Voice System installation process, you must
install both BlackBerry MVS components and provide the IP address, name and port number for your organization's
BlackBerry Configuration Database.
If your organization's environment requires high availability, you must have three computers available to host two
MVS Session Manager instances and a MVS Console. You can use high availability to provide minimum downtime for
BlackBerry MVS users if one of your organization's MVS Session Manager instances stops responding or requires
maintenance. The failover process is automatic, but you can perform a manual failover to perform scheduled
maintenance.
If your organization's environment includes multiple BlackBerry Enterprise Server instances, you can configure one
MVS Session Manager for each BlackBerry Enterprise Server, or you can associate all BlackBerry Enterprise Server
instances with one MVS Session Manager. You can install only one MVS Session Manager on a computer. If your
organization's users are associated with different PBXs, you must configure multiple telephony connectors, which
provide connectivity to each PBX. You require only one MVS Console to manage the BlackBerry MVS in each BlackBerry
Domain.
If your organization's environment already includes one MVS Console, during the BlackBerry MVS installation process,
you must install the MVS Session Manager only. You must also provide the host name or IP address, and the port
number for your organization's MVS Console.
To add another MVS Session Manager to your organization's environment, you must load security key stores that
the BlackBerry MVS generates during the installation process.
During the BlackBerry MVS installation process, you might be required to involve the administrators of your
organization's PBX, voice mail system, LAN, security network, or BlackBerry Enterprise Server.
Best Practices: Installing and configuring the BlackBerry
MVS
Best practices for installing BlackBerry MVS components
• The first time that you install the BlackBerry® Mobile Voice System software and associate it with a BlackBerry
Configuration Database, you must install both the MVS Session Manager and MVS Console. You can install the
components on the same computer or on separate computers.
• You can install the MVS Session Manager and MVS Console on dedicated physical hardware, or on a dedicated
virtual computer, or on the computer that hosts the BlackBerry® Enterprise Server. If you plan to install the
BlackBerry MVS components on the computer that hosts the BlackBerry Enterprise Server, your organization
can have no more than 500 users, and the BlackBerry MVS installation cannot be configured for high availability.
• You can install only one MVS Session Manager (which is a Windows® service) for each Windows Server® instance.
• You can install only one MVS Console for each BlackBerry Configuration Database in your organization's
environment.
Planning Guide Planning a BlackBerry MVS installation
10

• You can install multiple MVS Session Manager instances with a BlackBerry Configuration Database if you
configure the MVS Session Manager instances to use a single MVS Console.
Best practices for testing network ping time
• During times of high network use, the maximum time that a network ping can take to travel from the BlackBerry
MVS Server to the BlackBerry Enterprise Server or BlackBerry Configuration Database and back to the BlackBerry
MVS Server must be 240 milliseconds.
• During times of high network use, the maximum time that a network ping can take to travel from the BlackBerry
MVS Server to the PBX and back to the BlackBerry MVS Server must be 240 milliseconds.
Best practices for installing the BlackBerry MVS on a virtual computer
• If you install the BlackBerry MVS in a virtual environment, the virtual instance should perform as well as a
computer with two Intel® Xeon® 2.0 GHz processors with 4 GB of RAM and two drives that are configured as
RAID 1 or better.
Best practices for configuring the MVS Session Manager
• A MVS Session Manager can support multiple BlackBerry Enterprise Server instances when all BlackBerry
Enterprise Server instances use the same BlackBerry Configuration Database.
• You can associate each BlackBerry Enterprise Server with only one MVS Session Manager.
• A MVS Session Manager can support up to 10,000 BlackBerry MVS users.
• To add more BlackBerry MVS users, you can install additional MVS Session Manager instances. You must
associate each additional MVS Session Manager with at least one BlackBerry Enterprise Server that is not already
associated with another MVS Session Manager.
• If you configure BlackBerry device–initiated calling, you must configure a unique DID/DDI number for each MVS
Session Manager in your organization’s environment. You must also configure your organization's call routing
patterns so that the PBX can route the device-initiated calls to the MVS Session Manager that is associated with
the DID/DDI number.
Best practices for configuring the BlackBerry MVS for high availability
• When you configure the BlackBerry MVS for high availability, you install the MVS Console, the active MVS Session
Manager, and the standby MVS Session Manager on different computers in the same BlackBerry Domain. Both
MVS Session Manager instances use the same MVS Console and BlackBerry Configuration Database.
Best practices for configuring a telephony connector
• In a MVS Session Manager, you can configure one or more telephony connectors that provide connectivity to
the PBX. All telephony connectors in a MVS Session Manager can support up to 10,000 BlackBerry MVS users.
• You can use multiple telephony connectors to divide your organization's users between distinct nodes of the
PBX. You can configure telephony connectors for nodes of the PBX that exist in the same cluster or in separate
clusters in your organization's phone system.
• In a telephony connector, the value that you configure for the caller ID number must match the last six digits of
the outgoing ANI that you specify in your organization's phone system. If the value that you configure for the
caller ID number has fewer than six digits, that value must be an exact match for the outgoing ANI. If a complete
ANI does not arrive at the device (which might happen during international roaming, for example), the BlackBerry
MVS user might not be able to make or receive BlackBerry MVS calls.
Planning Guide Best Practices: Installing and configuring the BlackBerry MVS
11

Configuring call direction 5
You can configure the BlackBerry® Mobile Voice System to use PBX-initiated calling or BlackBerry device–initiated
calling for incoming calls and outgoing calls.
PBX-initiated calling
You can configure the BlackBerry® Mobile Voice System to use PBX-initiated calling. When a BlackBerry device
receives or sends a call request, the BlackBerry MVS sends a call request to the PBX so that the PBX can make a call
to the device. The device verifies that the call is from the BlackBerry MVS, and it either connects the caller to the
BlackBerry MVS user or initiates an outgoing call to the dialed number.
If your organization uses devices that operate on GSM® networks, PBX-initiated calling offers optimal performance
and reliability for BlackBerry MVS calls.
BlackBerry device–initiated calling
You can configure the BlackBerry® Mobile Voice System to use BlackBerry device–initiated calling. When a device
receives or sends a call request, the BlackBerry MVS sends a call request, which includes the DID/DDI number, to the
PBX. The PBX routes the call to the BlackBerry MVS. The BlackBerry MVS answers the call, verifies that the call is from
the device, and either connects the caller to the BlackBerry MVS user or initiates an outgoing call to the dialed number.
If your organization uses devices that operate on CDMA networks, device-initiated calling offers optimal performance
and reliability for BlackBerry MVS calls.
Planning Guide Configuring call direction

BlackBerry MVS high availability 6
BlackBerry® Mobile Voice System high availability consists of an active MVS Session Manager and a standby MVS
Session Manager. You can use high availability to help provide minimum downtime for BlackBerry MVS users if one
of your organization's MVS Session Manager instances stops responding or requires maintenance. The failover
process is designed to be automatic, but you can perform a manual failover before you perform scheduled
maintenance.
When you configure the BlackBerry MVS for high availability, you install the MVS Console, active MVS Session
Manager, and standby MVS Session Manager on different computers in the same BlackBerry Domain. Both MVS
Session Manager instances use the same MVS Console and BlackBerry Configuration Database.
Both MVS Session Manager instances connect to the MVS Console. The MVS Console periodically checks that the
active MVS Session Manager is healthy. If the health of the active MVS Session Manager falls below the failover
threshold or if the active MVS Session Manager stops responding, the MVS Console promotes the standby MVS
Session Manager.
If any of your organization's users are on BlackBerry MVS calls when the active MVS Session Manager stops
responding, the calls remain active but the users cannot use the features that are typically available to them during
a call. While the active MVS Session Manager fails over, the users cannot send or receive any BlackBerry MVS calls
until the failover process completes.
Planning Guide BlackBerry MVS high availability
13

You cannot configure high availability for the MVS Console because you can install only one MVS Console in a
BlackBerry Domain.
To manage your organization's users, if the computer that you installed the MVS Console on stops responding, you
should determine why the MVS Console stopped responding. Alternatively, you can install another MVS Console
instance and connect it to the active and standby MVS Session Manager instances.
Support for BlackBerry Enterprise Server failover
The BlackBerry® Mobile Voice System supports BlackBerry® Enterprise Server failover. If any of your organization's
users are on BlackBerry MVS calls when the active BlackBerry Enterprise Server stops responding, the calls remain
active, but the users cannot use the features that are typically available to them during a call. The users also cannot
send or receive a second call. While the active BlackBerry Enterprise Server fails over, the users cannot send or receive
any BlackBerry MVS calls until the failover process completes.
Support for PBX failover
The BlackBerry® Mobile Voice System does not support PBX failover. If any of your organization's users are on
BlackBerry MVS calls when the active PBX stops responding, the calls remain active until the BlackBerry device stops
receiving registration messages from the PBX. The users cannot send or receive any new BlackBerry MVS calls until
the PBX is active again or until you associate the affected telephony connector with the standby PBX.
How the BlackBerry MVS determines the health of MVS
Session Manager instances
The MVS Console determines the health of the MVS Session Manager instances by monitoring its connection to the
MVS Session Manager instances. If the active MVS Session Manager sends a network ping to the MVS Console at
regular intervals, the MVS Console keeps the MVS Session Manager active. If the active MVS Session Manager does
not send a network ping to the MVS Console every 60 seconds, the MVS Console promotes the standby MVS Session
Manager to be the active MVS Session Manager.
Conditions for failover to a standby MVS Session Manager
Failover from the active MVS Session Manager to the standby MVS Session Manager occurs when the MVS Console
stops receiving network pings from the active MVS Session Manager for 1 minute. If the MVS Console continues to
receive network pings from the standby MVS Session Manager, the MVS Console starts the failover process.
Planning Guide Support for BlackBerry Enterprise Server failover
14

Scenario: What happens after the active MVS Session
Manager stops responding
If the active MVS Session Manager stops responding, the response of the MVS Console depends on the health of the
standby MVS Session Manager. If the standby MVS Session Manager is healthy, the MVS Console promotes it to be
the active MVS Session Manager.
The following scenario assumes that the MVS Console is available.
1. The MVS Console determines that the active MVS Session Manager stopped responding, demotes the active
MVS Session Manager, and promotes the standby MVS Session Manager to be the active instance.
2. The active MVS Session Manager connects to the active BlackBerry® Enterprise Server.
3. The active MVS Session Manager registers the BlackBerry devices with the PBX.
4. An error message appears on the MVS Console to indicate that a MVS Session Manager is unhealthy.
You must resolve any issues with the unhealthy MVS Session Manager before the MVS Console can promote it to be
the active instance again.
