Aha, that did the trick!

True, but this is trickier: It's asking for channel driver specific
information, for which at this moment I haven't found the proper
abstraction function. If there is such one at all.

I don't know if adding it to the [globals] section with "=> yes"
is too broad, or that it has to define the function to be exported.

Personally I was looking for an export function in the chan_zap-driver
itself, just like there is a load and unload function :-)
