3 1. Introduction Smartphones and tablets are everywhere and many enterprises are considering deploying Unified Communications for their mobile devices. When integrated with the corporate environment, mobile unified communications provides many features and capabilities for mobile devices. 2. What are the drivers for deploying Mobile Unified Communications? There are several factors that can drive the decision to deploy Mobile Unified Communications. Some of these drivers help determine the need for a mobility solution and others drive the decision of which system to deploy. Reduce mobile costs Lower costs for cellular voice plans (excessive voice minutes), international calls, and international roaming. Increase productivity Improve accessibility and responsiveness by extending voice services to the mobile workforce. Leverage investment in communications infrastructure Deploy Unified Communications applications to mobile devices. Improve in-building coverage by utilizing internal WLAN for enterprise voice network. Support for BYOD Enable employees to use their familiar personal mobile device ( Bring You Own Device ). Provide support for many devices, including Android, BlackBerry, ios devices (iphone, ipad, ipod Touch), and Nokia. Some of these drivers can justify deploying Mobile Unified Communications on their own. The following section describes how Mobile UC benefits are realized for these drivers. Reduce mobile costs For many companies, mobile phone costs are the primary reason for deploying a Mobility solution. These costs are somewhat unpredictable and vary with travel and business activity. End users are not always willing or able to use the least cost method of placing phone calls on mobile phones. Most mobile phone service plans have a fixed number of minutes per month or are part of a pooled plan with multiple devices. The total amount of minutes per month must be managed and ideally adjusted as calling trends vary. This is not always possible or feasible due to fees for changing rate plans or resources required to monitor monthly usage. International calling is one of the most expensive, and often the most abused, form of mobile phone calls. Users should be able to place any call without worrying about the cost. A Mobility system, leveraging the enterprise voice network, can eliminate high mobile international calling costs. Deploying Mobile Unified Communications for Cisco PAGE 3

4 International roaming costs are high and quickly add up. A Mobility system which utilizes VoIP over Wi-Fi or 3G/4G cellular data will eliminate these charges. For additional savings when a data network is unavailable, it can use local in country access numbers, rather than relying on roaming, to dramatically reduce international calling costs. Without a Mobility system, mobile costs can get out of control quickly and there are few ways to monitor when these conditions arise. Mobility systems can substantially reduce mobile costs in several areas. Increase productivity Many individuals have several contact phone numbers (corporate desk phone, mobile phone, home phone etc.) making it difficult for a caller to reach them. Some PBX systems can ring multiple internal devices, but most can only forward to one external location at a time (and when that happens the PBX loses control of the call). This is not very flexible. Also if a call is forwarded to a mobile phone and is unanswered, that call will go to the mobile phone s voic (not the corporate voic system). In this case, the user has multiple voic systems to manage. Mobility systems make it easier to reach fellow co-workers by allowing mobile users to dial internal extensions (rather than the full corporate number). The proper internal extension and name is also displayed by the PBX, rather than the mobile phone number. With a Mobility system, a mobile user advertises one unique contact phone number (the corporate phone number), the system handles calling all phone devices, all unanswered calls go to the corporate voic system, and the mobile user has flexible dialing options. This simplifies contact and provides a more responsive and accessible mobile workforce. Mobile Presence also increases productivity. Employees can look at their contacts and determine who is available or where they are located before phoning, thereby making communications more efficient. Leverage investment in communications infrastructure Many companies have made large investments in deploying Unified Communications to regular desktop systems. Additionally, campus-wide WLAN infrastructure has been provided for laptop users. It would be beneficial if these investments could be extended and leveraged for other uses, such as for mobile users. Mobility systems can help extend those UC applications to mobile users by providing integration to the corporate voice network for phone calls, integrated and unified voic , access to Presence information, Instant Messaging, etc. Mobility systems utilize the internal WLAN to provide VoIP over Wi-Fi. This improves the in-building signal coverage for mobile users and allows a more effective and better quality use of the mobile device when inside a campus environment.

5 Support for BYOD Corporate I.T. is being driven to support personal Bring You Own Device. It s not desirable to support only a limited number of mobile devices that were certified or which client software only works on some units. Users are demanding to bring their own devices into the corporate environment and use them effectively. A robust Mobility solution should support a wide variety of devices (Android, BlackBerry, iphone, ipad, ipod Touch, Nokia, etc.). The Mobility solution should be flexible to support future devices as they become available. The Mobility solution should be device agnostic. Additionally, the Mobility system should work consistently with all types and manufacturer s devices. The same client software should operate and be managed as a single application. Client software should be easy to use and should utilize the mobile devices familiar interface. 3. What factors influence which Mobility system to deploy? While determining which Mobility solution to deploy, consider the following factors. Most solutions cannot deliver on all these factors. They capitalize on one or two areas but are fall short in other areas. Gives the best Return on Investment (ROI). Ensures robust security. Provides the best user experience for end users (increasing productivity). Delivers support for a wide variety of smartphones. Simplifies deployment and daily system administration. 4. Cisco Mobility overview What does Cisco offer for Unified Communications? Cisco Systems provides several Unified Communications (UC) solutions, including the Cisco Unified Communications Manager (CUCM) IP Telephony system. It is a very desk phone centric solution. Some vendors have been able to develop applications and tools for desk phone control and integration with other Cisco ancillary systems. Cisco is still relatively new in Mobile Unified Communications. Some applications are available, but are somewhat limited in their functionality. The CUCM system has a few out of the box applications that can be used for Mobility. CUCM call forwarding basic PBX style forwarding to a secondary device. Cisco Unity voic Call Handler basic Interactive Voice Response (IVR) menu system with some transfer and announcement features. Cisco IP Communicator software application which provides desk phone capabilities on a PC system. Deploying Mobile Unified Communications for Cisco PAGE 5

6 Cisco Mobile 8 SIP based mobile application for ios (iphone, ipad, etc.), requiring a Wi-Fi connection. Cisco Jabber for Android SIP based mobile application for Android, requiring a Wi-Fi connection. Nokia Call Connect for Cisco mobile application for Nokia Symbian-based smartphones which provides cellular and VoIP over WLAN calling. Cisco Unified Mobile Communicator / Cisco Unified Mobility Advantage end of sale mobile application system. BlackBerry MVS (Research In Motion s BlackBerry Mobile Voice System) mobility application for BlackBerry phones only. As you can see, Cisco offers a complex mix of solutions with several limitations. Not only does it burden I.T. with having to deploy and manage a separate solution for each mobile device platform, but also becomes an unviable option in an environment of mixed PBXs since its mobility solutions work only with a Cisco PBX system. A detailed description of each of these products follows. When reviewing these systems as a solution for Unified Communications, consider if they truly address your Mobility needs and would provide a complete solution. The Cisco Unified Communications Manager (CUCM) supports a flexible call routing scheme which can be utilized for forwarding calls to off-premises or to external ancillary systems. Incoming calls typically will ring a desk phone and after some period of time (set by the administrator) the call can be routed to an alternate location. At this point call control is typically lost as the CUCM does not control devices that are not registered (directly configured and administered) to the CUCM. Think of this method as simple desk phone forwarding for unanswered calls. The Cisco Unity voic system has a built-in call control feature called Call Handlers. These are individually programmable procedures which can play a menu to a caller, accept caller key press input and direct calls. Call Handlers are not as full featured as a full ACD/IVR (Automated Call Director / Interactive Voice Response) system that might be found in a Call Center environment, but they can be quite complex and offer some flexibility for mobility call routing. Cisco does not provide any pre-configured or built-in Call Handlers for specific Mobility routing; all Call Handler procedures need to be custom created by the customer or integrator. The Cisco IP Communicator provides a software based telephone application ( soft phone ) which runs on a Windows system. This is a typical application which allows a user to place and receive phone calls via their computer similar to using a regular desk phone. Almost all desk phone functions are replicated in the IP Communicator. A headset and microphone is required (either built in to the PC system or via an externally connected or USB style headset). Cisco promotes the IP Communicator as a Mobility tool as it can be used away from the user s desk and is available anytime the user is connected to the corporate LAN (either directly or via VPN). The IP Communicator performs quite Deploying Mobile Unified Communications for Cisco PAGE 6

7 well when connected to the corporate LAN (where QoS can be guaranteed). However quality and performance can degrade significantly when using external networks (hotels, residence based broadband, etc.) and especially over Wi-Fi (airports, coffee shops, etc.) where QoS is not provided. Cisco Mobile 8 is a SIP based application for the iphone only. This is the closest to a true Mobility application. Cisco Mobile 8 provides integration to the Cisco Call Manager voice network and allows the user to place and receive calls over an integrated Wi-Fi network. Internal extension and external calling, access to voic , conference, transfer, hold, park and transfer to/from the desk phone is available. Contacts are available based on the directory integration with the Call Manager. A Wi-Fi connection is required in order to use Cisco Mobile 8. Authentication is automatic when using the internal corporate WLAN. When connected to an external WLAN, a VPN connection must be established first. Cisco Mobile 8 can transfer a Wi-Fi call in progress to the cellular network ( hand-out ), Mobile 8 cannot transfer a cellular call to Wi-Fi ( hand-in ). Cisco Mobile 8 does have the ability to send calls over the cellular 3G data network. By default this feature is disabled. Cisco recommends using this feature with care as data throughput over 3G is not always reliable. The Cisco Mobile 8 application cannot itself place a regular cellular call. If the user attempts to place a call when not connected to Wi-Fi, an error message is displayed and the user must place the call with the device s native dialer application. Cisco Jabber for Android is an Android application that allows the user to place and receive calls using the internal corporate WLAN. Cisco Jabber for Android supports transfer, conference, hold, and resume. Calls can be handed off to the mobile provider s network from Wi-Fi coverage. Calls in progress can be transferred between the Android device and a Cisco Unified IP Phone. A connection to the Enterprise network using Wi-Fi is required to use Cisco Jabber. When not connected to the internal Wi-Fi directly, a VPN connection is required from the device to register the application. VPN must be configured before using Cisco Jabber. Cisco Jabber is supported on several devices running Android Not all devices are supported. Cisco Unified Mobile Communicator and Cisco Unified Mobility Advantage have been announced as end of sale and will not be available after March BlackBerry MVS (BlackBerry Mobile Voice System) is the mobile application developed by RIM (Research In Motion) for BlackBerry phones. It has many features including Voice over Wi-Fi, transfer to desk phone and integration with the corporate voic system. It does have a limited Wi-Fi to cellular handover, but this transfer can only happen once per call. Deploying Mobile Unified Communications for Cisco PAGE 7

8 The biggest drawback is that MVS can only be used with BlackBerry devices. MVS requires integration with the BlackBerry Enterprise Server (BES). 5. ShoreTel Mobility An alternate approach ShoreTel Mobility is a comprehensive Mobile UC solution that integrates with an organization s existing enterprise communication applications and infrastructure, and extends PBX/UC capabilities to leading smartphones and tablets. It not only integrates with a Cisco PBX/UC system, but also other leading systems such as Avaya, Nortel, Microsoft and ShoreTel. ShoreTel Mobility works even if your infrastructure includes multiple PBX vendors (such as with multiple sites/campuses or from acquisitions). ShoreTel Mobility has two components: the Mobility Router and the RoamAnywhere Client. The Mobility Router integrates with the enterprise PBX and UC systems and extends capabilities to mobile devices via the RoamAnywhere Client. The RoamAnywhere Client is natively integrated with the mobile device and gives users access to features and capabilities such as extension dialing, hold, transfer, presence etc. It also gives users the freedom to connect from any location (office, home, hotspot) and over any network (Wi-Fi, 3G/4G, cellular).

ShoreTel Mobility is an award-winning solution that differentiates itself from the Cisco solutions in several ways. Deploying Mobile Unified Communications for Cisco PAGE 8

9 One solution for mobility. One solution to manage. One solution to deploy. ShoreTel Mobility is a single solution that simultaneously supports a broad range PBX/UC systems and mobile devices (Android, ios, BlackBerry OS, Symbian/Nokia.) Unlike with Cisco, there is only one application to deploy and manage simplifying administration for IT. The Mobility Router is easy and uncomplicated to deploy. The ShoreTel Mobility Router is a self-contained appliance and is easily configured via a web interface. Unlike Cisco which requires the administrator to perform software updates and configuration from multiple servers to deploy the settings and updates to each smartphone platform type, with ShoreTel Mobility s central client management portal bulk configuration and software updates can be made with a single click across all devices, eliminating the need for manual upgrades and end user intervention. Unlike Cisco which requires a separate application for each service, ShoreTel delivers all enterprise communication services (voice, presence, IM, security, etc.) within a single unified application. For example, Cisco requires two clients on both iphone and BlackBerry platforms with one app to support cellular calling and Presence while another app supports Wi-Fi calling. ShoreTel Mobility has an integrated and voice-optimized SSL VPN which secures voice communications between the RoamAnywhere client and the Mobility Router. Once fully configured the system itself rarely requires configuration modification or maintenance. System updates are applied and installed via the same interface and only take minutes to complete. Client updates are delivered over the air. The ShoreTel Mobility system is the easiest to use for end users. The client application integrates with the native telephone application. Users dial and receive calls from a familiar looking keypad and in call features and options are readily available through on screen buttons and menu selections. The ShoreTel Mobility system is the most cost effective on a daily basis (recurring licensing, maintenance, etc.). Mobile cost reduction is accomplished by reduced or eliminated international roaming and long distance costs, eliminated overage charges and the overall cost of mobile devices is reduced by eliminating unneeded mobile phones and licensing. Additionally, many users find the advantage of giving up their corporate desk phone and using their mobile device exclusively (thus reducing the expensive cost of desk phones).

10 ShoreTel Mobility also reduces telecom costs by offering: Reverse Dial 1 - The ability to have the mobile phone call the enterprise PBX to receive inbound cellular calls. This will save costs in areas where outbound cellular calls are free or less expensive than outbound land line or trunk calls. Country based access numbers 2 for outbound calls when not on Wi-Fi, the mobile phone must contact the Mobility system. When the user is international, this can result in international roaming and international call charges. When a local in-country access number is provided (by the enterprise voice network), ShoreTel Mobility can utilize the local number, avoiding the international call. 1 Reverse Dial is available on BlackBerry, iphone and Nokia. 2 Country based access numbers are available on BlackBerry and Nokia. The ShoreTel Mobility system provides increased productivity as users are easier to reach and are more responsive. A unified voic capability eliminates the need to check and manage multiple disparate voic systems; all voic is delivered to the common corporate voic system. The ShoreTel Mobility system provides better mobile reliability by leveraging the low cost in-building Wi-Fi network. All calls to mobile devices use the corporate voice network (which is typically much lower in cost per call) and thereby reduces the need for mobile plans with extensive number of minutes. The ShoreTel Mobility system provides the best mobile UC security solution. With ShoreTel Mobility s use of AES-256 encryption, IT administrators can be assured that their mobile voice communications are secure. Robust security is insured with strong device-level and user-level authentication, including digital certificate use, and automatic initiation of application-layer SSL VPN when users are outside the enterprise firewall. Additionally, security for ShoreTel Mobility is an integrated product. Cisco Mobile 8 and Cisco Jabber requires both Cisco ASA for SSL VPN and Cisco IPSec. VPN is required for the other Cisco applications. Also, IPSec is less efficient for VoIP traffic due to larger perpacket overhead. Deploying Mobile Unified Communications for Cisco PAGE 10
