I have several USA bought cordless phones where the caller id is not displayed as we use DTMF as conversion here and in USA it is FSK. I saw couple of DTMF to FSK convertors which when used would display the caller id in USA bought caller id phones. When I checked with a seller in ebay for buying this device he told that this acts as a splitter cum caller id and I need to remove the existing splitter and install this as a splitter (this looks exactly like a splitter). It costs around Rs.650/-. I just wanted to check if someone has installed this and if it works as claimed. If I remove the existing splitter and if I install this as a splitter will my internet connection work?
