To use some more than the standard features like ISDN routing, you need enabled features inside the MAX. The wanted funktions are included in the TAOS operating system of the three MAXen, we are talking about.

But by default, the VOIP hashcode is disabled (like many others) and so you cannot configure this feature. Some other wanted features are available first after TAOS Rev. 9.x .

	Having the VOIP feature code enabled, you are able to use the DSP cards with its VOIP functions.
