Sim Johnson of Broadcast Bionics wrote us posing this question: "What is the best way to establish a call between two Z/IP ONE codecs over a private network with no access to the Internet? Would you suggest using SIP, or is there a way to make a direct connection without a ZIP Server?"
Our Kirk Harnack responds:
You can use a direct "TSCP" call. Configure each of the ZIP ONE's WAN port network parameters with a normal internal IP address. To call the other unit, Press the "CONN" button and set the "Device Name" to IP address of the other unit. Delete any "Group Name" that is present so that it indicates "(For TSCP Calls)" and set the "Call Type" to "TSCP." You should now be able to connect to the other unit.
Be sure to set the Codec parameters as appropriate for the available bandwidth.
