I've found strange issue in 3CX voip phone v1.2.12 installed on Motorola Milestone v2.2.1. When 3CX phone is active, all GSM calls (incoming and outgoing) has one-way audio (I hear all conversation but the other side doesn't hear me). I found simillar issues only on VoIP, but now this happends only in GSM calls (voip has two-way audio and works without problems). I've tried to use handset and Jabra mobile headset - without result. When I shut down 3CX, everything back to normal. Anyone found simillar problem ?
