2 UC500 SIP Trunking Overview

2.1

Product Description

Cisco's UC500 is a purpose built appliance for SMB solutions that provides IP PBX,

voicemail, switching, VPN, firewall & optional wireless functionality. The IP PBX &

voicemail features are based on Cisco Unified Communications Manager Express (CME)

& Cisco Unity Express (CUE). The switching, VPN, firewall & wireless are based on

IOS features while management is provided via the Cisco Configuration Assistant (CCA)

tool.

UC500 provides the following benefits:

• Cost-effective, converged data and voice solution in an appliance.

• Key system/small PBX features plus innovative convergence applications

for up to 48 users with the use of an optional expansion switch.

• Intuitive GUI for easy installation, adds, moves, and changes.

• Firewall & VPN support, based on US DoD certified IOS firewall

technologies.

• Optional integrated Wireless LAN support for mobility with abilty to

extend wireless coverage

UC500 offers voice-mail and automated attendant capabilities for IP and

analog phone users & these are fully integrated into the appliance.

2.2 UC500 SIP Trunk Qualification and Templates

The main focus of the document is to define guidelines in developing a UC500

configuration template & validate a configuration that works & enables

communication between the UC500 and service provider's SIP call agent. Basic

voice features including on-net and off-net calling, call transfers and forwarding,

voicemail access, and any other network-based voice services upon which a

PBX/voicemail system depends would be the more common ones tested. More

customer-specific features such as hunt-group definitions, paging groups are left

to VARs and customers to configure.

2.3

Managed Access Router

Cisco strongly recommends that providers have a well defined demarcation point such as

a Cisco IAD / ISR that is managed by the provider & provides network access services

for IP voice and data traffic. The Managed Access router provides:

NAT ALG functionality

QoS for SIP Trunk calls & SLA guarantees

WAN conversion to Ethernet on UC500

Well defined point of troubleshooting for SP & customer
