It would be optimal if the whole GSM side could run autonomously and the CPU in fact unpowered / suspended during a call in the normal case (no listening sockets on Wifi for example). I don't know what management traffic is needed to the telephony network during the call, hopefully it just needs service when the call completes, or you wake the CPU anyway from motion or touchpad because you are about to end the call from your side. How this would fit into USB-based telephony modules I didn't figure out yet :-) but it would definitely make a BIG increase in this "talk time" figure if the only thing sucking real power during the call is the GSM module itself and the audio subsystem. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFH442MOjLpvpq7dMoRAhScAJ4hWH0Dfln1b4X6crfbAFVdsg5VQQCgiB3N LoJkPWfITMPnZfDi2sUA39Y= =nRbh -----END PGP SIGNATURE-----
