picture. I know the firmware on the Nortel is old, so I'm guessing that
libpri is sending something that the Nortel does not know how to handle.
Is there a way to dumb down what libpri sends? From everything I've read
PRI is an evolving standard - and older devices may struggle with newer
extensions/developments. (This might be very handy for users trying to talk
to old pbx's.)
Is there a workaround?
Thanks,
Michelle
