optiPoint 410/420 - Using with Asterisk, Configuration Guide 3
Overview
1OverviewUsing the products from the Siemens HiPath portfolio you can design communication solutions
for a wide variety of requirements (i.e. scalability and features). Apart from IP communication
systems, optiPoint telephones with SIP protocol are an integral part of these solutions. These
telephones can - due to the standards used - easily be integrated into open SIP-based environ-
ments.
This documentation helps you to start up a Siemens optiPoint SIP telephone with only a few
steps. It also shows the preparation of the SIP system, using an Asterisk open source PBX en-
vironment as an example.
2 System Requirements Asterisk runs on the following operating systems: Linux, BSD, Mac OS X.
As long as you use Asterisk for VoIP only, no specific hardware requirements have to be met.
If a larger number of codec transcodings is necessary, you should use a more powerful PC
hardware.
In case of compatibility questions regarding protocols or hardware please refer to
http://www.asterisk.org (see Section 9, "Reference List").
3 Configuration of AsteriskWe assume that you are familiar with the installation and basic usage of an Asterisk environ-
ment. If you need further help, there is a wide variety of literature available as well as compre-
hensive information in the world wide web (see Section 9, "Reference List").
We will explain the basic statements in the configuration files sip.conf, extensions.conf and
voicemail.conf using an running sample configuration for two optiPoint telephones.
