Hope this is ok to post this on here? But I am in somewhat of a dilemma. A good friend has one of these voip pbs based on sailpbx.com which was installed on a linux SME server. www.contribs.org.
Now this has worked as a voip only server for simple communications for himself from home to his office. He now would like to use this system to the full, and has bought an ISDNcard Openvox B400. The card is recognized, but as to how to make it route incoming calls is rather beyond both of our knowledge. If anyone knows this system, and could help, then he would be more than happy to pay consultancy.
