Best advice I can go with is try to isolate when and where the noise is occurring. As you say its random, I would its some type of interference and maybe not a problem with the phone. Does it happen in certain locations, is there something else nearby running, does someone else with a different phone have the same problem? Just for kicks, try installing a different dialer app from the Play store and use that for awhile. Do everything you can to try and isolate it and give a report back here.
