I have been trying to get the Mizu Voip Server to work for several days now.  Kept getting an iscallshop field missing error - eventually I had to edit SQL server to make this go away by adding a bit field called iscallshop.

But, now that I have the system supposedly running without errors, I can not find any useful information on how to connect my server to my Voip provider.  I need to bring calls in from the world using my voip provider, who provides me with SIP credentials.  I can easily connect to the voip provider with a number of different softphones, including 3CX - its simple - I just type into the phone's settings a username and password for my account, and then a sip domain name.  The softphone instantly connects to the provider for incoming and outgoing calls.

None of the information in your tutorial, admin guide or help files tells how to do this simple and actually make it work.  How can I connect the server to my Voip provider so that I can receive calls from them, and send calls through them?  They act as a Sip trunk.  Do I use traffic senders?  This is the most basic of functions in order to make the mizu server act as a PBX - without being able to send and receive actual voice traffic, the server isn't usable.

How can I connect to a Voip provider and actually send and receive calls?
