  • Page 4: Uc500 Sip Trunking Overview

    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 &...

    Securing IP Telephony installations such UC500 is a topic that is beyond the scope of this document. Security is an area in which VARs may provide additional value to customers, if executed properly. Cisco’s IOS firewall, for example, can be configured on UC500 to enable the appropriate access-lists and other elements of the firewall.

  • Page 8: Requirements

    3 Requirements Hardware Requirements The UC500 appliance, supported Cisco IP phones, and a service provider managed access router (highly recommended). An Uninterruptible Power Supply (UPS) is strongly recommended for UC500, which runs the embedded Unity Express module. This appliance is fairly robust but nevertheless subject to errors in the event of sudden power loss.

  • Page 9: Configuration

    4 Configuration The UC500 may be configured with either the Cisco Configuration Assistant (CCA) or command line interface (CLI). This guide documents the CCA configurations tasks as far as possible with CLI used only to customize the template further to work with the provider.

    4.3.1 With the UC500 in a default configuration, launch CCA on the workstation attached to a FastEthernet port. CCA begins with a prompt to connect. Select “Create Community” to add this UC500 to a new community as follows: Figure 4.3.1 Create community for CCA © 2008 Cisco Systems, Inc. All rights reserved.

  • Page 15 SIP Trunking takes place, and will be addressed in the next section of this document. Cisco recommends that VARs leave the “Switching”, “Routing”, “Smartports” & “Ports” portions at their default settings unless integration into the provider network requires the addition of IP interfaces, VLANs or static routing decisions etc.
  • Page 16 DNS settings are applied for PCs based on the SP requirement or if the VAR / customer intend to change the default DHCP configuration. Cisco recommends that VARs leave this alone unless there is a compelling need for this.
  • Page 17 “Device Properties -> IP addresses” – this is particularly relevant if the SIP Trunking provider uses domain names instead of IP addresses to route SIP calls between devices Figure 4.3.8 default DNS settings for UC500 © 2008 Cisco Systems, Inc. All rights reserved.
