1. Introduction These Application Notes present a sample configuration of the Motorola MC70 and MC9090 wireless handheld multifunction mobile computers integrated with Avaya Communication Manager. The Motorola MC70 and MC9090 handheld computers, shown below, run the Microsoft Windows Mobile 5 operating system. With the Avaya IP Softphone application for the Windows Mobile 5 operating system installed, the MC70 and MC9090 become voice enabled mobile endpoints of Avaya Communication Manager. The Motorola Voice Quality Manager (VQM) application complements the Avaya IP Softphone application taking advantage of device specific capabilities of the MC70 and MC9090. Features of the VQM application are highlighted in Section 1.2. The Motorola MC70 and MC9090 running Avaya IP Softphone are integral components of the Avaya Intelligent Retail Store Solution [7]. MC70 MC9090 While there are inherent differences in feature functionality between the MC70 and MC9090, these differences are not relevant to the operation of the Avaya IP Softphone or the Motorola VQM application. For additional information, see [1, 3]. 3 of 22

1.1. Avaya IP Softphone for Windows Mobile 5 The Avaya IP Softphone for Windows Mobile 5 is a fully-functional business class softphone for mobile handheld computers. Avaya IP Softphone for Windows Mobile 5 enables mobile employees roaming a campus or building the ability to receive and make voice calls while also having access to the business class features of Avaya Communication Manager such as multiple call appearances, directory dialing, transfer and conference to name a few. Below is the graphical user interface of the Avaya IP Softphone for Windows Mobile 5 running on the Motorola MC70. Avaya IP Softphone for Windows Mobile 5 on MC70 Avaya IP Softphone for Windows Mobile 5 can operate in one of three modes as described below. For this sample configuration, the Road Warrior mode is used. Road Warrior: The most commonly used mode. Both audio and call signaling are transported via the IP network. The Softphone operates in this mode when used as a wireless communications device. Telecommuter: Call signaling is transported via the IP network but the voice stream goes through the PSTN. This is useful when utilizing a Windows Mobile 5 based PDA on an IP network where either quality of service or available bandwidth is suboptimal for the voice stream. 4 of 22

Shared-control: Users can dial from their IP network connected PDA through their desk phone. This is useful when storing a primary contact on the PDA. 1.2. Motorola Voice Quality Manager The Motorola Voice Quality Manager (VQM) is a software application which resides on the MC70/MC9090 device. The VQM application interacts with the Avaya IP Softphone enhancing the voice capabilities of the MC70 and MC9090 devices. VQM provides the following set of features: Dynamically detects voice calls and prioritizes voice packets by modifying the Differentiated Services Code Point (DSCP) field in the IP packets that carry voice. DSCP marking is one of the components of the WiFi Multimedia (WMM) specification that addresses Quality of Service (QoS) over WiFi. Marking the DSCP field of the IP voice packets is useful only when the wired and wireless LAN infrastructure is setup to recognize priority marked packets. QoS priority marking using Differentiated Services requires all applications and elements within a network to use consistent DSCP values for the QoS policies to be effective. The DSCP value is a configurable parameter in Avaya Communication Manager for call signaling packets as well as voice packets [Section 4.3]. The Motorola VQM application sets the DSCP value to 56 during installation. To change this value the Windows Mobile 5 registry must be edited and the MC70/MC9090 must be rebooted. Contact Motorola for steps to make any changes to the VQM DSCP value. Enables the Acoustic Echo Canceller for voice calls when a headset is not being used. A VQM icon in the title bar of the MC70/MC9090 indicates the audio modality currently in use (e.g., speakerphone, handset, headset) for voice calls. A single tap of the VQM icon will toggle the audio modality between handset and speakerphone while on an active call. Selecting the VQM icon for 2 seconds while on an active call will show the VQM Audio Control window which shows the status of the Acoustic Echo Canceller, the DSCP marked packet count and VQM version number. 5 of 22

2. Network Topology The network implemented for the sample configuration is shown in Figure 1. Avaya Communication Manager is running in a Co-Resident configuration with Avaya SIP Enablement Services (SES) on an S8300C Server hosted by an Avaya G350 Media Gateway. The G350 Media Gateway is also serving as a DHCP server for both wired and wireless endpoints. The wireless LAN supports the Motorola MC70 and MC9090 as well as an Avaya 3631 wireless phone. Note: The configuration of the wired and wireless LAN infrastructure is beyond the scope of these Application Notes and therefore is not discussed in detail. These Application Notes assume the Motorola MC70 and MC9090 are already connected to an 802.11 wireless network that has been engineered to support voice traffic. Also, while the Avaya Communication Manager in the sample configuration is a Co-Resident configuration, Avaya SES is not required to support Avaya IP Softphone for Windows Mobile 5 on the MC70 and MC9090.
