Default Galaxy Nexus: Issues with Phone calls

I am having issues with the phone calls...When I initiate a phone call, it goes black screen and the dialer shows up after ~20 secs...then i am able to proceed with the call..same issue with the incoming calls as well..I attend the call and its idle for 20 sec and then i hear the voice....

I flashed the stock rom with stock kernel..the baseband and RIL seem to match...

Flashed the radio: radio-maguro-i9250xxlj1

I am not sure if the issue with kernel or modem....any help pls...
