Question

I have a GE Cordless 5.8 gigahertz handset and digital answerer. I can see the red light flashing during an incoming call, but hear no dial tone and no ringing. I just replaced the battery. The handset either says "READY" TALK" or "UNAVAILABLE", but I cannot dial outgoing calls. I can receive audio messages on the answerer, but no dial tone, no ring, and not able to dial outgoing calls!
