that is because dect is designed first as a voice system, with roaming built in, just like GSM (its kinda a "low power gsm" system, the protocol is almost the same). > Although the system comes with Philips phones, we were able to get GAP > compatible phones to work without any issue from manufactures like > Siemens,and Panasonic its critical for interoperability that you get GAP phones, that is the only cross vendor standard, anything else you risk getting into a closed system where you can only use that makers phone. The encryption algorithm is operator specified, so GAP isnt required but its a good idea in my opinion. The entire DECT spec is free except for GAP, ETSI only releases that under an NDA and money paid, which is silly, but they do that to try to get something if you want to make an interoperable phone, and its this reason why some of the cheaper DECT systems dont do GAP. > Most of the entry level one's do not support encryption and even if they > had, they were WEP based, that can now be cracked in a few minutes. wep can be broken in less than 60 seconds on even an old PC. There are many published papers dating back the last couple years on that.
