FreeTDM currently has the same limitation unless your telco/switch sends
polarity reverse on answer. If polarity reversal is enabled, then FreeTDM
will not put the channel in state UP until the telco reverses the polarity
to signal answer.

This has nothing to do with the dependency on DAHDI for Digium cards btw.
