Default Weird call issues

Ok this is strange.

I can make calls but can't hear the dial tone or the other person, but they can hear me just fine.
The speaker is ok since I can hear the end-of-call beep.

It's the actual call that has problems. Any ideas on what I can do to fix this?

I would appreciate any ideas (but flashing another ROM is not possible atm sorry )

EDIT: As randomly as it had occured, it just sorted itself out.
