Try the push-to-talk apps on the SD7
These services list the SD7 as supported. The SD7 has no front screen: the app runs on the handset and you work it with the PTT key, the channel knob and the SOS key. Pick one and try what it can do.
Tap the talk button on the screen for the next call, hold it to talk; the tabs switch the app's screens.
