Can you advise on which dect systeem to use on PBXnSIP including repeaters ? I am looking for a stable product which can handle 6 to 8 channels at the same time and a number of handsets and that was tested with pbxnsip.
For normal puposes Siemens Dect (eg 470IP /301d) is working fine, but you'll need a repeater for each base and that can only handle two calls.

thanks
