The problem is using the AT command set, not whether or not serial communications can carry voice. Remember that T1 is just a really fast serial line. The AT command set is a remnant of low power computing. You issue a command to get started with voice mode. Then you set it in record mode, and look to see if there is incoming audio. Then you issue a command to send audio when you have some in your queue. > > > > ----- Original Message ----- > > From: "Gary" <[EMAIL PROTECTED]> > > To: <[EMAIL PROTECTED]> > > Sent: Wednesday, June 04, 2003 7:17 AM > > Subject: [Asterisk-Users] Modem => Serial ? > > > > > > > Now with the usual discussion which arises with compatible internal > > > modems for FULL DUPLEX voice etc... > > > > > > It really makes me think (again) about serial communications.... > > > > > > Most external modems will now talk at 115k2 so maybe some will explain > > > when/what/how/etc of why a serial interface could NOT be developed ?? > > > > > > Gary > > > . > > > > > > > > > > > > _______________________________________________ > > > Asterisk-Users mailing list > > > [EMAIL PROTECTED] > > > http://lists.digium.com/mailman/listinfo/asterisk-users > > > > > > > > > > _______________________________________________ > > Asterisk-Users mailing list > > [EMAIL PROTECTED] > > http://lists.digium.com/mailman/listinfo/asterisk-users -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
