I have a Turbo, most recent software, Advanced Calling enabled. Phone works perfect with outgoing calls, texts, data, voicemail notifications, and I have a problem with incoming calls. I've had a lot of calls recently that when I answer, will be dead air, no voice, and the person on the other end says the incoming ring tone just stops. I can call them back without problems. It happens about 3/10 calls. If my wife, who has Advanced Calling also, calls, it works ok. Lately, I've also been getting calls to voicemail without any incoming ringing. The caller will report 3-4 rings before they get transferred. If I turn off Advanced Calling, the problems resolve, but I lose SVD. Anyone had this problem or know of a fix or solution?
