Cisco Wireless IP Phone Integration and Troubleshooting
Integration Solutions for Cisco Wireless IP Phones
Cisco wireless IP phones are industrial-grade Wi-Fi handsets designed for professionals who are mobile within office, campus, warehouse, hospitality, health-care, retail or other environments where IT management requires more control, security and ruggedness than can be easily achieved in BYOD-style communications. The current generation of Cisco wireless IP phones are hardened devices with enhanced security and simplified manageability through tight integration with Cisco Unified Communications Manager. Built-in Bluetooth radios allow users to add Cisco or third-party wireless headsets for hands-free operation to maximize productivity. Support for the 802.11ac Wi-Fi standard improves consistency, range, density, and roaming capabilities.
Critical factors for a successful deployment of Cisco mobile wireless IP phones include a well-engineered network infrastructure with proper placement and configuration of wireless access points (APs) plus careful integration with Cisco Unified Communications Manager (CUCM) or Unified Communications Manager Express (CUCME) for call control. Progent's Cisco-certified CCIE network engineers and Wi-Fi integration consultants can help you successfully design, implement, manage and troubleshoot Cisco wireless IP phone solutions by providing services that include wireless site surveys to analyze usable RF spectrum, determine which types of Cisco access points should be used and where they should be placed. An important deliverable of Progent's wireless site surveys is the production of heatmaps showing your site's coverage plan.
Progent can also help you utilize Session Initiation Protocol (SIP) for call control with Cisco CUCM and Cisco Unified CME management tools. (See SIP and CUBE infrastructure solutions: SIP trunks and Cisco CUBE integration expertise.) Progent's Aironet wireless access point consultants and Meraki access point experts can help you deploy and manage APs that support your wireless IP phones. In addition, Progent's Cisco wireless infrastructure consultants can help you configure Cisco access points and wireless LAN controllers to implement advanced Quality of Service (QoS) features such as Call Admission Control (CAC) to optimize your wireless IP phone ecosystem.
Cisco's 8821 and 8821-EX Wireless VoIP IP Phones
Cisco's 8821 and 8821-EX Wireless IP Phones provide mobile on-premises workers the benefits of voice over wireless LAN (VoWLAN) communications in environments that support 802.11a/b/g/n/ac Wi-Fi. The 8821 Wireless IP Phone features a 2.4 inch color display, a durable case rated Mil-SPEC 810G for shock resistance and IP67 for dust and splash resistance, long-life batteries, a built-in full-duplex speakerphone, and an integrated Bluetooth 4.0 radio for wireless headsets.
Other features include enhanced encryption support for SHA-1 and SHA-2 signatures, fast and secure roaming (FSR) using 802.11r (Fast Transition) and Cisco Centralized Key Management, automatic certificate renewal on the device with SCEP support, and support for XML-based applications such as push to talk. A USB-to-Ethernet adapter allows you to download WLAN profiles for fast and accurate configuration. The 8821 works with a broad selection of Cisco Aironet and Cisco Meraki indoor and outdoor access points, and SIP call control is supported with Cisco Unified Communications Manager and Cisco Unified Communications Manager Express.
The 8821-EX Wireless IP Phone adds ATEX Class 1, Zone 2 and CSA Division 1, Class 22 compliance. This helps prevent sparking during temporary exposure within potentially combustible environments. The 8821-EX also features a case made of industry-standard yellow plastics, which makes it easy to locate the 8821-EX in an emergency.
Cisco's Legacy Wireless IP Phones
Several generations of Cisco wireless IP phones have reached end-of-sales status and may no longer be supported by Cisco. These legacy devices have been superseded by handsets with enhanced features such as bigger screens, improved resistance to shock and harsh environments, advanced Bluetooth radios, stronger encryption, faster roaming, compatibility with a broader selection of Cisco access points, and support for 802.11ac Wi-Fi. Progent offers management and troubleshooting support for legacy Cisco wireless IP phones and can also help you upgrade to current devices, which typically requires modernizing your WLAN ecosystem.
Legacy Cisco wireless IP phones supported by Progent include the Cisco Unified Wireless IP Phone 7925G and the Cisco Unified Wireless IP Phone 7925G-EX. Both these devices offer a more rugged design than earlier models and support Bluetooth 2.0 including Extended Data Rate. The 7925-EX includes ATEX Class 1, Zone 2 and IP64 compliance and is enclosed in a yellow case for easy recognition in the event of an emergency. Progent can also help you maintain or upgrade legacy 7921G model wireless IP phones, for which Cisco has announced end of support.
