There are a number of different linking technologies for repeaters. Most of them are open source or use open source technologies. So far we have echolink operating great within the project. We have been looking at the other linking technologies and have started to make plans at integrating them with our project.
The first one we are going to take on is the AllStar Link Network. This system is based on the open source VOIP switch called Asterisk. This means we have to add Asterisk to our build. This is not a big deal and was pretty easy, we currently undergoing some performance tests to see what impact adding Asterisk to the build has on the performance of the repeater.
Look for more soon on our integration with this link network.
