To answer my own question, at least in part - there *is* a standard for this, called V.150 (= V.150.0 + V.150.1), and Googling for that turns up the sort of thing I was looking for. (Sometimes, a bookshop is better than the Internet. I found a reference to this standard in an O'Reilly book called "Switching to VoIP". However, even this book says that if you need legacy modem services, you should just keep some POTS lines around to support them :-) I notice that the source for Asterisk 1.2.10 doesn't refer to V.150, but Asterisk SVN at least decodes the frame type in frame.h / frame.c. Does this mean there is some plan for this in the pipeline? Thanks, Brian. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-dev mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-dev
