Why do I have to start the call first before plugging in my headphones?

[Technarch]

I can't have them in the jack beforehand because then even though the call is running, I get silence.

I need to start the call, then plug them in. That way I'll get sound.

Are other phones like this?

Hmmmm... that's strange. Have you done a reset lately? Did it work originally and this just started?

[Technarch]

It has always been this way, with all firmware versions that I've tried..

Why don't you try it Morganizer? Grab a pair of headphones.
