Cisco Smart Business Communications System Teleworker Set Up


The Cisco Smart Business Communications System is a unified communications solution for small businesses that provides voice, data, video, security, and wireless capabilities while integrating with existing desktop applications like calendar, e-mail, and Customer Relationship Management (CRM).

This document explains how to set up a teleworker using the Cisco 870 Series Integrated Services router (ISR), (for example, the Cisco 871 Integrated Services router) with the Cisco Smart Business Communications System solution. This document is to be used with the Cisco Smart Business Communications System Setup document included in the box. This document is also available online at the following URL: http://www.cisco.com/en/US/products/ps7293/prod_installation_guides_list.html. Please refer to Section 3, "Set Up PSTN, SIP Trunking, and Teleworker Connections" on page 6 of the Cisco Smart Business Communications System Setup document for basic set up instructions.


Note This document assumes that you have completed up to Section 2 of the Cisco Smart Business Communications System Setup document.

If PPPoE, check the PPPoE checkbox, and enter the username and password provided by the ISP.

If static IP address, choose Static IP, and enter the internet IP address, subnet mask, and default gateway address.


Note The ISP provides all information required in the WAN Parameters window.


Step 3 From PC-1, test the Internet and WAN link by accessing an internet page.
