I thought it might be the unit (jabra 250v), so I purchased a jabra BT8040 and it does the same thing. It will pair but I can't communicate, but I can hang up and adjust the volume with the headset. My phone is a brand new 8310 that is replacing a 8700c which had no problems.
I have the very same jabra250 when it disconnects i have to take the battery out reset it may last one night or two this is my second 8310 same thing,thats one thing I want is a wireless headset im thinking about getting a q9h motorola I spent 120 mins with blueberry got nothing resolved they sent me a e-mail with bluetooths that was supposed to work with it the 250 was one of them,I love the phone But this is something I use. good luck
I have the 8130, so I don't know if this will help, but I use the Plantronics Voyager 510 and haven't had any problems with (*knock wood*) connection, voice dialing, etc.
Yesterday, I was on the BT with a friend for 20 minutes and she thought I was on a landline! That sold me!
