I've managed to pair up my SE T637 with a 2007 Sedan with Navi. It works pretty well with one small problem. When I dial out using the car, if nobody answers by the third or fourth ring, the car just hangs up by itself. Since most voicemails/answering machines pick up after the fourth ring, this means I don't get the opportunity to leave a message.

Does anybody have any suggestions on how to tweak this one? I don't know whether the tweak would be in the car or the phone. I looked through both manuals and did some googling to no avail.

I figure there is a time-out after about 10 seconds from dialing. And my phone/carrier combination is just too slow at connecting to get through within the time limit.

Oddly, if I dial from the keypad on the phone, it transfers the call to the car, and keeps ringing until I manually hang up.
