The Cisco SPA525G 5-Line IP Phone with Color Display (Figure 1) is an excellent choice for businesses that require an enhanced user experience with a hosted IP telephony service, an IP private branch exchange (PBX), or a large-scale IP Centrex deployment. The SPA525G uses industry-leading SPA voice over IP (VoIP) technology from Cisco, with high-quality hardware providing additional connectivity via Bluetooth for headset connectivity, Power over Ethernet (PoE) (802.3af), or a Wireless-G client (802.11g).
Standard features on the Cisco SPA525G include five active lines, VLAN-capable dual switched Ethernet ports, 802.3af PoE support, a 3.2-inch QVGA color display, a full-duplex, high-quality speakerphone, a Bluetooth interface for headset connectivity, a Wireless-G (802.11g) client, a 2.5-mm stereo headset port, and a USB 2.0 host port. Each line can be configured independently to use a unique phone number (or extension) or can use a shared number that is assigned to multiple phones. The power supply for the SPA525G is sold separately. The optional SPA500S 32-Button Attendant Console adds up to 64 buttons for receptionist applications.
The Cisco SPA525G IP Phone continues to improve the user experience with VPN and video surveillance applications. The SPA525G comes with an embedded VPN client that allows remote users to securely connect to their phone system and make calls over the Internet, without the need of additional hardware. The SPA525G IP Phone also provides users the ability to view video feeds from Cisco PVC2300 video surveillance cameras, allowing users to quickly see different locations around the business in order to improve physical security. The SPA525G is part of the SPA500 Series IP Phones that are a robust portfolio of small business phones that provide a rich user experience with HD voice, on-phone applications, and intuitive menu options.
The Cisco SPA525G provides encrypted signaling, media, and provisioning information, using state-of-the-art technologies such as Session Initiation Protocol (SIP) over Transport Layer Security (TLS), Secure RTP, and HTTPS/SSL to secure communications between the user and service provider. Cisco SPA Secure Remote Provisioning provides a highly secure mechanism for the service provider to remotely manage the phone/user configuration and the device software upgrades.
The Cisco SPA525G IP Phone can also be used with productivity-enhancing features such as VoiceView Express, and Cisco XML Applications when interfacing with Cisco Unified Communication 500 Series in SPCP Mode.
