Okay, so, i'm not sure if this is a long standing bug or somehow a configuration misshap (our server only really just started using this, so perhaps we overlooked something?)

However, everything seems to work fine, Handheld Shortrange, and backpack long range all works fine. not a single problem

However, upon getting in to any vehicle, using its built in LR comms does not work.
I can edit it with alt+p just fine and set the right channels, however using both standard and alternate voice activation do not work..i get the message in the bottom right saying i'm transmitting, but nobody receives it. this goes for everyone on the server, not just me. anyone using the vehicle radios ends up not been transmitted, and can only be heard via local voice.

I'm just wanting to know if this is a common problem or something that perhaps we've messed up? i gave a quick search and couldn't find anyone else mentioning the problem.
