My girlfriend has Verizon's wireless phone service and an Audiovox CDM-8600 phone. For some reason, when she tries to talk on her phone from inside her apartment, there are random patches of no service and when she walks into those areas, she can still her the other person on the line just fine, but the other person can't hear what she's saying. It's so weird because it really just happens here at her apartment and it only cuts out what she's saying. Does anybody here who knows a lot about cell phones have any idea what might be causing this? Thanks.
