Instead of bothering the channel driver, sounds like you just need to modify libpri then to handle the Q931 coming from a source other than a zap channel. Would be much simpler I hope to handle it this way than to write a special driver. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
