Note: The 8- and 16-user models of the Cisco Unified Communications 520 Series support an optional integrated WLAN access point for secure WLAN connectivity. As part of the Cisco Smart Business Communications System, the Cisco Unified Communications 520 Series also supports the optional external Cisco AP 541N clustering wireless access point that enables mobile networking (data and voice) for office spaces, helping increase employee flexibility and productivity. The 24-, 32-,48-user and upgraded 64-user models of the Cisco Unified Communications 520 Series do not support an optional integrated WLAN access point. These models can use the Cisco AP 541N clustering wireless access point to enable WLAN functions.

Architecture Features and Benefits
Table 1. Platform Features and Benefits
|
Feature |
Benefit |
|
Solution packaging |
The solution offers various fixed configurations, eliminating the guesswork. Each configuration is equipped with the appropriate number of feature licenses for call processing, voicemail, and Cisco Unified IP Phones, simplifying the product structure. A modular slot is available in most of the configurations, allowing expansion of the system with additional PSTN or analog station interfaces. The appropriate number of fixed digital signal processors (DSPs) is packaged with each configuration. |
|
Default system configuration |
Although packaged to support various deployment configurations, the solution comes with a Cisco Smart Assist predefined configuration from the factory, allowing for rapid deployment of the product in the field: • Preassigned phone extensions
• Background images for color IP phones
• Ringtones for IP phones
• Music-on-hold
• Dial plan
• Voice and data VLANs
• Firewall settings
With the appropriate licensed base platform, expanding the system is easy; simply connect the companion Cisco Catalyst Express 520 Switch and connect phones to the new PoE Ethernet ports. |
|
Integrated voicemail and Automated Attendant |
Voice messaging raises the level of professionalism, productivity, and customer service available to small business customers with built-in Automated Attendant and advanced voicemail capabilities. With Professional Automated Attendant, all calls can be handled efficiently and reliably 24 hours a day. Callers can dial by extension number of the group or person they are trying to reach or use the Dial-by-Name feature when they do not know a specific extension. Voicemail extends your organization's productivity by allowing employees to access messages at any time from any telephone. Both internal and external calls to a busy or unattended phone are forwarded to the user's voice mailbox and are greeted with the user's personalized greeting. Integrated messaging allows you to check your voicemail using Internet Mail Access Protocol (IMAP) email clients, including Microsoft Outlook, Outlook Express, or Lotus Notes. You can also access voicemail features using the XML display on Cisco Unified IP phones. |
|
Ethernet connectivity with quality of service (QoS) |
Ethernet connectivity is provided for IP phones or wireless access points by PoE ports that provide connectivity speeds for up to 100BASE-T Ethernet technology without the need for additional power modules. Most Cisco Unified IP phones include a 10/100 switch with QoS to provide PC desktop connectivity to the network. Optimized QoS is provided for IP phone and desktop configurations. The QoS level helps ensure that voice over IP (VoIP) traffic takes precedence. Voice and data traffic have separate VLANs. Port security limits unauthorized access to the network. |
|
Power failover |
A power failover feature on the base configuration allows access to the PSTN line if a power outage occurs. When power is lost, the first foreign exchange office (FXO) PSTN trunk is directly connected to foreign exchange station (FXS) analog port, allowing for calls to be placed and received. |
|
Recorded announcements for callers: music on hold (MOH) |
The process for providing customized MOH announcements is simplified with a dedicated MOH port, allowing small-business owners to play recorded announcements to their callers by simply plugging the audio source into the provided 3.5-mm mini-jack. You can also use. wav files stored on flash memory of the system. MOH is an audio stream that is played to PSTN and VoIP G.711 or G.729 callers who are placed on hold, reassuring the callers that they are still connected to the called party. |
|
Deployment options |
Depending on the configuration, the Cisco Unified Communications 520 Series can be deployed as a desktop unit, wall-mounted, or installed in a standard 19-inch (48.26-cm) rack with an optional rack-mount kit. The Cisco Unified Communications 520 Series can be deployed in a wired (standard) configuration, using the LAN wiring to connect the system components. As an alternative, the Cisco Unified Communications 520 Series can be deployed in a wireless-only configuration with the Cisco Small Business Pro IP Phone SPA525G, eliminating the need for cables and making deployment easier. |
