Motorola V65p

If this phone has a similar user interface to the V60P the speakerphone can be used for both PTT and Voice calls with the clamshell closed. On the V60P there is a small button between the antenna and the headset jack on the top of the phone which toggles between the two modes. I have personally used the V60P and know this to be true, and it actually works well right from the waist.

This is NO LONGER true as of the latest s/w upgrade which fixed the PTT latency. You can NOT use the speakerphone for regular phone calls with the flip closed.
