Roger is getting bizarre caller ID issues with his wife's phone and sometimes he can't connect at all. Leo says it's likely an issue with the carrier. Caller ID comes from the carrier and Leo says it sounds like they're doing some odd things with it that the phone is having trouble understanding.
As for not being able to connect to the home phone, Leo says that also sounds like a strange provider issue. Roger's carrier is an "MVNO" or third party that buys service from Sprint and then resells it. Leo suggests calling the carrier and and the MVNO and get them to fix the issue.
