Well, after some observing, i've decided that i have an issue with the calls.
Sometimes the call just drops, it interrups and i have to call again, or get called again. Tried different radios, thought it was the issue, but now i think there is some other problem?
Used Android system info app to see if anything gets logged while this happens, but radio call log seems clear, no errors.
It happens in any areas, open, indoor, while moving or standing still. The call just drops.
I have ARHD 53 right now installed on it, but had this issue with earlier roms too
It doesn't happen always. I've tried to recreate the situation, by calling myself on other phone, a few times, left the phones talking to each other, but the call didnt drop lol. tried a few times, still no drop.
