Thank you for using Apple Support Communities!
So it sounds like the Music app is somehow starting on its own and over riding the Phone app, disconnecting your call.
I would use steps 1, 3, and 5 of the iPhone Troubleshooting Assistant found here http://www.apple.com/support/iphone/assistant/phone/.
If you get to step 3, close all the apps that are running. Here is step 1 to get you started:
To restart iPhone, first turn iPhone off by pressing and holding the Sleep/Wake button until a red slider appears. Slide your finger across the slider and iPhone will turn off after a few moments.
Next, turn iPhone on by pressing and holding the Sleep/Wake button until the Apple logo appears.
Is iPhone not responding? To reset iPhone, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds, until the Apple logo appears.
If your device does not turn on or displays a red battery icon, try recharging next.
All the very best,

Tx for suggestions. I was a bit desperate since I use my phone for work so went the restore factory settings route. So far so good but time will tell. On the upside battery does not run down as fast.
