d) some modems expose voice as "GSM codec frames over UART"
You got me curious here: are there any modems out there other than FreeCalypso that offer the quoted special feature? Someone actually paid me to add this special feature to FreeCalypso a little over a year ago, so I reason that it must be sufficiently non-standard that they couldn't find a commercial off-the-shelf modem that can do this feat.
