When I posted my last message about the cellsocket, I hadn't thought to try incoming calls. (I bought the cellsocket to use only for outgoing calls.) Unfortunately, I cannot get the cellsocket to work for inbound calls. CallerID does not work even though I have a GSM phone. The cellsocket answers the phone and then starts ringing any attached phones after answering. Most importantly, levels are so low once the call is completed that neither party on the call can hear the other. Very strange, since outbound calls work so well. Hopefully I just have a defective cellsocket. Regards, Jeff
