The Cisco SPA525G2 5-Line IP Phone with Color Display is an ideal choice for businesses that require a great user experience with a hosted IP telephony service, an IP private branch exchange, or a large-scale IP Centrex deployment. The SPA525G2 features SPA voice over IP technology with high-quality hardware providing additional connectivity via Bluetooth, PoE (802.3af), or a Wireless-G client (802.11g).
Salient Cisco SPA525G2 IP Phone features are five active lines, VLAN-capable dual switched Ethernet ports, 802.3af PoE support, a 3.2” QVGA color display, a full-duplex, high-quality speakerphone, a Bluetooth interface, a Wireless-G (802.11g) client, a 2.5 mm stereo headset port and a USB 2.0 host port. Each line of the phone 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 Cisco SPA525G2 IP Phone further enhances the user experience with VPN and video surveillance applications. The phone has an embedded AnyConnect Secure Sockets Layer VPN client that allows remote users to securely connect to their phone system and make calls over the Internet, without the need for additional hardware. The SPA525G2 IP Phone also provides users the ability to view video feeds from Cisco WVC2300 and PVC2300 Business Internet Video Cameras, allowing them to quickly scan locations around the business in order to improve physical security.
The Cisco SPA525G2 IP Phone further provides encrypted signaling, media and provisioning information, using technologies such as Session Initiation Protocol over Transport Layer Security, Secure Real Time Protocol and HTTPS to secure communications between the phone 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 software upgrades.
The Cisco SPA525G2 IP Phone can also be used with productivity-enhancing features such as VoiceView Express and Cisco XML applications when connected to the Cisco Unified Communication 500 Series in SPCP mode.
