Data Sheet
The Cisco SPA 525G2 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. Part of the Cisco Small Business Series, the SPA 525G2 uses industry-leading
SPA voice over IP (VoIP) technology from Cisco, with high-quality hardware providing additional connectivity via
Bluetooth, PoE (802.3af), or a Wireless-G client (802.11g).
Standard Cisco SPA 525G2 features 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, 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 SPA 525G2 is sold separately. The optional SPA 500S 32-button attendant
console adds up to 64 buttons for receptionist positions.
The Cisco SPA 525G2 IP Phone further improves the user experience with VPN and video surveillance applications.
It includes an embedded AnyConnect Secure Sockets Layer (SSL) 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 SPA
525G2 also provides users the ability to view video feeds from Cisco WVC2300 and PVC2300 Business Internet
Video Cameras, allowing users to quickly see different locations around the business in order to improve physical
security. The SPA 525G2 is part of the Cisco SPA 500 Series IP Phones, a robust portfolio of small business phones
providing a rich user experience that includes HD voice, on-phone applications, and intuitive menu options.
The Cisco SPA 525G2 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 Real Time
Protocol (SRTP), 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 SPA 525G2 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.
Features and Product Specifications
The Cisco SPA 525G2 IP phone can easily grow with your business. New features can be added to the phone over
time via firmware updates. New employees or employees who need to move to another location can simply plug in
their preconfigured phones anywhere on the network, and the network will recognize the change. The phone also
supports wireless network connectivity, providing unrestricted placement without the cost of running network cabling.
