  • Page 5: Introduction

    Many interesting call routing options are possible using Asterisk to control the SPA8800 gateway. Asterisk can be configured to trunk the SPA8800's four FXO ports together into a trunk group. A trunk group allows the PSTN lines connected to the FXO ports to be over-subscribed and shared among all configured analog and IP phones, effectively lowering telephony costs by not requiring a dedicated line per phone.

  • Page 6: Overview

    Small Business Community ATA Support Overview Configuring the SPA8800 is a relatively trivial task and is similar to configuring any of the Sipura / Linksys / Cisco ATA and SPA9000 Voice System devices. Troubleshooting configuration problems due to incorrectly typed information in configuration fields requires advanced network and Asterisk troubleshooting skills.

  • Page 7: Requirements

    Before you configure your Asterisk server for the SPA8000, you need to gather some basic information: Static IP address for the SPA8800. By default, this device is a DHCP client, but will be of no use to you if it is assigned a new dynamic IP address periodically. In this document, I use 192.168.2.237/24...

  • Page 25: Troubleshooting Rejected Because Extension Not Found

    Looking through extensions.conf and sip.conf, all is normal, yet the inbound call does not ring on extension 101. The problem in this scenario is that the SPA8800 Line N's dialplan has been incorrectly configured and is routing the call to extension 101 while extensions.conf is routing the call elsewhere.
