This document is about how to set up the BioStation 3 Intercom with Linphone, the open-source VOIP.

Linphone.org hosts a free SIP service that allows users to make audio or video calls using SIP addresses via the domain sip.linphone.org. You can create your own sip address, for example, "sip:john@sip.linphone.org" by creating an account on the Linphone webpage, and your friends can call you using this SIP address.
