Has anyone been able to get the PTT Express client fully working on the TC70? When testing in conjunction with a MC2100 I see the following issues:

a) If a group broadcast is made from the 2100 , I can't make a private response from the TC70 ( not sure which key this function is mapped to?)

b)  If a group broadcast is made from the TC70 , I can't make a private response from the 2100 as I get the constant error tone when the PR key is pressed.

OS build on the TC70 is 090114
