Cisco SPA525G

Cisco SPA525G Core Features

The Cisco SPA525G 5-Line IP Phone with Color Display 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).

Why use the Cisco SPA525G?

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 SPA932 32-Button Attendant Consoles add up to 64 buttons for receptionist applications.

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.
