Introduction The Tango Accelerator integrates with enterprise voice mail systems to provide a single voice mail for both the desk phone and the business mobile phone. This document addresses the way that the Accelerator integrates with the Cisco Unity voice mail to provide single voice mail services for employees that are using the Accelerator services. Supported Versions This document addresses integration with Cisco Unity 3.1 and Unity 4.1. Integration Strategy The goal of the Accelerator is to integrate with the current environment being used by the enterprise with minimal disruption to any of the current networking equipment that is being used but still provide the Accelerator value set of accessibility and control for the enterprise. There are three major areas in which the Accelerator needs to inter-work with the Cisco Unity solution. These are: Voice Mail Deposit Voice Mail Retrieval Message Waiting Indications Voice Mail Deposit Voice Mail deposit for an Accelerator subscriber can happen either when the desk phone number is called and not answered or when the subscriber s business mobile is called and not answered. The user experience of the calling party should be the same no matter how they choose to contact the subscriber. In addition, the possibility that a call in the wireless network would be routed to a wireless carrier s own voice mail system has been avoided. Voice Mail deposits from the business mobile phone will use a predefined Unity Routing Rule for Forwarded Calls. The predefined rule will route all calls forwarded from a subscriber extension to the subscriber s greeting. The Accelerator uses the same routing rules as the PBX uses to route calls to voice mail. There should not be a need to modify the routing rules to support the Accelerator. March 2015 CONFIDENTIAL Page 3 of 27

Voice Mail Retrieval Voice Mail retrieval on the business mobile phone is intended to use the mobile phone s GUI as provided. In other words, the way a wireless user accesses their wireless voice mail is the same way that the user will access their enterprise based voice mail. Voice Mail retrieval from the business mobile phone will use a predefined Unity Routing Rule for Direct Calls. The predefined rule will route all calls directly routed to the Unity server to the subscriber s logon conversation. The Accelerator uses the same routing rules as the PBX uses to route calls to voice mail. There should not be a need to modify the routing rules to support the Accelerator. Message Waiting Indication (MWI) The Accelerator facilitates the delivery of Message Waiting indications from the enterprise voice mail system to the wireless handset. The message waiting indications provided on the wireless phone are synchronized with the message waiting indications provided on the desk phone. When a message is deposited in the voice mail box either by calling the mobile number or the desk number, the message waiting indication will be displayed on both the wireless phone and the desk phone. When a voice message has been handled, the message waiting indication is removed from both the desk phone and the mobile phone. March 2015 CONFIDENTIAL Page 4 of 27

Network Deployment The following section describes the network topology of the Accelerator to support voice mail deposit/retrieval as well as message waiting indication. Voice Mail Deposit/Retrieval To provide integration between the enterprise environment and the employee using a wireless phone, a single voice mail box is supported. To support the employee when using their wireless phone, they must be able to retrieve voice mail easily from their wireless phone as well as make sure any unanswered calls to the wireless phone are routed to the voice mail for deposit. The Accelerator is intended to augment the way that the enterprise employee communicates, and with this in mind, all calls from the wireless network requiring voice mail deposit or retrieval services will be routed via an enterprise PBX for access to voice mail. This ensures that the voice mail interactions behave in the same manner that they do today without modification. Accelerator and Unity Voice Mail with Cisco Call Manager Figure 1 shows the manner in which the Accelerator interfaces to the Unity voice mail via the Cisco Call Manager. Figure 1 Accelerator and Unity VM with Cisco CM PBX March 2015 CONFIDENTIAL Page 5 of 27

Calls from the wireless network that require voice mail retrieval or deposit services are routed to the Accelerator for handling over a SIP trunk from the Cisco Call Manager. The Accelerator takes the incoming call, matches it to the function that it needs to perform and hands the call to the Cisco Call Manager for routing to the Unity Voice Mail Platform. The following routing instructions are provided to the Cisco Call Manager Voice Mail Deposit this call is handed to the Call Manager with the Unity pilot as a forwarded call (Cisco CM uses diversion header but also history info and Remote Party ID are added) Voice Mail Retrieval this call is handed to the Call Manager with the Unity pilot Call Manager interfaces to the Unity Messaging system to provide information required by Unity to identify voice mail box and other items to get the call handled appropriately. Accelerator and Unity Voice Mail with TDM PBX Figure 2 shows the manner in which the Accelerator interfaces to the Unity voice mail via the TDM PBX Figure 2 Accelerator and Unity VM with TDM PBX Calls from the wireless network that require voice mail retrieval or deposit services are routed to the Accelerator for handling over a SIP/PRI gateway from the TDM PBX. The Accelerator takes the incoming call, matches it to the function that it needs to perform and hands the call to the SIP/PRI gateway for routing to the Unity Voice Mail Platform. The following routing instructions are provided to the PRI Gateway/TDM PBX: March 2015 CONFIDENTIAL Page 6 of 27

Voice Mail Deposit This call is handed to the PRI Gateway/TDM PBX with the Unity pilot as a forwarded call (this includes the remote party Id which indicates call forward) Voice Mail Retrieval This call is handed to the PRI Gateway/TDM PBX with the Unity pilot TDM PBX interfaces to the Unity Messaging system to provide information required by Unity to identify voice mail box and other items to get the call handled appropriately. Message Waiting Indications There are a number of ways to communicate between a messaging system and the PBX concerning message waiting indications. Three of these methods include Analog Communication Use of tones on the line to indicate to the handset that a voice mail message is waiting SMDI - Simple Message Desk Interface which is a serial connection between the PBX and the Messaging system that conveys not only Message Waiting Indication but also information about calls being delivered to the voice mail system. Proprietary This interface is specific to the Voice Mail system and PBX combination. For example the Cisco Call Manager and the Unity Message server use a TAPI based protocol to communicate this information. The Accelerator uses a SMDI link to collect information about Message Waiting Indications. A SMDI interface allows the Accelerator to listen in on the information without impacting the way that the Voice Mail server and the PBX are communicating. In order to supply Voice Mail Message Waiting Indication from voice mail servers that support an SMDI interface only, the SMDI feed from the voice mail server must be split. This allows voice mail information to be received by the PBX for displaying on the desk phone, and sent to the Accelerator for display on the wireless phone. The splitter is a passive splitter which takes the input from the voice mail system and supplies it onto two different RS- 232 feeds. Figure 3 SMDI Splitter March 2015 CONFIDENTIAL Page 7 of 27

A serial device server is used to carry the RS232 feed supporting SMDI over the corporate LAN infrastructure. This allows the SMDI splitter and serial device driver to be located close to the voice mail server itself and the Accelerator server to be located regionally or centrally. The topology of the PBX and voice mail server will ultimately dictate how many ports are needed on the serial device server. There are two ways to provide SMDI to the Accelerator. First, if Unity is already using SMDI to communicate to the PBX, a data tap can be put on the connection that provides Accelerator the information it needs. Alternatively dual notification can be added for PBXs that use proprietary means to get MWI information from Unity. Figure 4 Unity SMDI Feed Topology The figure above shows the way that the Accelerator would be connected into the Unity Voice Mail Server. The diagram indicating without current SMDI input shows the way in which the additional SMDI link would be connected into the Accelerator duplicating the information shared with the PBX. This would include the configuration of Unity to provide duplicate notifications and creating serial port access via a Serial Device Server. The diagram indicating with current SMDI input shows the tap on the line so that the output of the Unity System can be forked to the Accelerator. March 2015 CONFIDENTIAL Page 8 of 27

Unity and Redundancy A Unity system can be deployed in a redundant configuration. This implies that message waiting indications can be received from the primary server and the secondary server (when the primary is out of service). In order to ensure that the Accelerator receives the message waiting indications in this type of redundancy deployment the following different scenarios are supported. The first scenario to consider is the case where a redundancy Unity System has been deployed with a PBX that only supports a single SMDI feed. In this case the system should have been deployed with a data splitter that allows the feeds from the two Unity servers to be connected to a single port on the PBX. The Accelerator needs to tap this connection (using the RS232 tap) between the data splitter component and the PBX itself. By tapping the SMDI link at this point, the Accelerator will receive message waiting notifications from the primary and secondary unity servers which ever one is active at any point in time. This tap is connected to a Serial Device Server which allows for geographic separation of the RS-232 SMDI feeds the Accelerator. Figure 5 Redundant Unity with Single SMDI Feed The second scenario that needs to be considered is the case where the Unity system has been deployed with a PBX that support dual SMDI feeds. In this case the Accelerator needs to tap each SMDI link so that it can have a complete picture of the message waiting indications created by the Unity system. Then the two SMDI tap streams are combined with a data splitter to create a single feed for the Accelerator. This single RS-232 feed is connected to a Serial Device Server which allows for geographic separation of the RS- 232 SMDI feeds the Accelerator. March 2015 CONFIDENTIAL Page 9 of 27

Figure 6 Redundant Unity with Dual SMDI Feed The final case that needs to be considered is the case where the Unity server is connected to the PBX via a proprietary link. In this case, duplicate notifications need to be created over the SMDI link so that The Accelerator can provide message waiting indications to the wireless handsets. The SMDI link from each Unity server (primary and secondary) and combined using the data splitter and then this combined feed is connected to a Serial Device Server which allows for geographic separation of the RS-232 SMDI feeds the Accelerator.

Figure 20 Accelerator Unity Subscriber Bulk MWI Log File Verifying Changes made to the Unity Database Verifying changes made to the Unity Database is an optional step. This can be done to ensure changes made by the Accelerator subscriber MWI Bulk Edit Tool are acceptable. Note: the Accelerator tool can reverse any changes made by running the tool with the remove option. In order to verify the changes, the Cisco Unity Tools Depot Datalink Explore tool is used to export a before version of the Notification MWI table and an after version of the Notification MWI table so that they can be compared. Unity Tools are available from www.ciscounitytools.com. While the Data Explorer tool is available for 3.1, it complains about missing tables with error messages. These can be ignored as those tables are not being modified by this tool. The only different between 3.1 and 4.1 is that the table being modified in 3.1 is the NotificationMWI table instead of the vw_notificationmwi. March 2015 CONFIDENTIAL Page 24 of 27

In order to export a CSV file containing the contents of the Notification MWI table, the following steps should be done: 1. Open the Unity Tools Depot 2. Under the Diagnostics Tools category - select the DataLink Explorer tool. 3. Under the Table Name Scroll Bar select the vw_notificationmwi table for display 4. In the File menu to create a CSV file with the data select the Export entire grid to CSV file option Figure 21 Cisco Unity Data Link Explorer Creating a CSV input file The CSV file that is used as input into the Accelerator subscriber MWI Bulk Edit Utility needs to have three different values in it. These are Extension this field identifies the Unity Subscriber uniquely. First Name this field helps provide informative information in the log file in the case of an error Last Name this field helps provide informative information in the log file in the case of an error There are a couple of ways to create this file for use with the Accelerator subscriber MWI Bulk Edit Utility. Using the Subscriber Information Dump create a file that contains all users and edit out the subscribers that don t require any changes Using the Subscriber Information Dump create a file that contains a subset of the users that require changes Manually create a file that contains the subscribers to change. Note: If the Subscriber Information Dump method is used, please delete the first line of the file as this contains header information. March 2015 CONFIDENTIAL Page 25 of 27
