I have Vonage Voip service. I'm using a Linksys RTP300 router. It connects to a Panasonic KX-TDA50 pbx system. My problem is that the RTP300 adds a leading "1" to the caller id information and sends that info to the KX-TDA50. Unfortunately, the pbx also adds a leading "1" so my caller id on the telephone system begins with "11". This double “11” means I cannot one button dial when trying to return the call. I have several lines POTS going into the pbx. The caller id on these lines have only the single leading “1”. In the pbx, the adding of the leading "1" is a global command which affects the entire system so I cannot turn it off. Is it possible to turn off the adding leading "1" on the RTP300? Or is there a Linksys/Cisco or other manufacturer’s adapter that converts the Vonage Voip to telephone without adding the leading “1”? Thanks.
