I just purchased an Apple 4S iPhone. I also have a bluetooth Panasonic cordless phone (model # KX-TG7621) at home. I have encountered serious porblem after I utilized the 4S bluetooth function to connect to my Panasonic cordless phone. When I used the cordless handset to answer an outside call to my cell phone, the outside parties can not hear my voice but I can hear them clearly. The ring tone and other bluetooth features between the 4S and the cordless are operated properly. Any recommendations to troubleshoot this problem would be deeply appreciated.
