Charles,

Thanks - that fixed the hard lock.   There is still the issue of mpg123 
not terminating and holding asterisk on exit but that is minor.  So in 
summary:

    The above patch from Charles fixes the lockup in the zaptel drivers
    Jeff Rizzo's "#undef AUDIO_RINGCHECK" in the wcfxs driver lets
    zaptel actually answer POTS lines
    Change the path to the music files in musiconhold.conf fixes the
    linux path issue.

Yeah! - I actually have a working Asterisk PBX system :-)

Thanks for all the help.
