My problem is solved. I had the same problem described here but it was solved by removing just one recording app I had installed and did not know it is causing this echo problme for a few weeks. To exclude all the problems regarding your downloaded apps you should back up your phone and without restoring reset your iphone to a new iphone. Again do not do a restore. Then try calling someone. You problem might have been resolved.
