Mount an rPi3 in an old phone case. If impedence of handset doesn't match rPi audio input/output, buy one of the "retro" handsets with smartphone compatible audio jack - it has impedence matching built in. P ros: mostly already done except for buttons/display and final assembly/mounting cleverness (standoffs for the win!). Cons: you'll have to hook up buttons to GPIO and test how to read them. Ditto for display, or buy a designed for rPi display. Anticipated answer: right :) the whole point of this exercise was NOT to spend a week in hardware hacking. Maybe it's easier to just buy a retro handset, and plug it into an existing rPi case or other mini-pc with more standard keypad/display. _______________________________________________ Linphone-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/linphone-users
