Problem going off hook with ATA SPA112

I have an SPA 112. I can reigister without problems to my Voip supplier. I can get a wired desk analogue phone (with external power) to go off hook, get dial tone and make calls, BUT when I attach a BT Freestyle 750 DECT phone or a non extrernal powered desk phone to the same line (FXS port) I can not get the phone to go off hook and so can not get dial tone or make calls.  Can someone suggest what the solution to my problem could be ?

Thanks,

Don

Re: Problem going off hook with ATA SPA112

Check the pinout cable. You must use a 2 wire RJ11 (tip and ring only).

Check "FXS Port Power Limit" value of your SPA under Voice-Regional-Miscellaneous menu'.

Check "FXS Port Polarity Configuration" of SPA under Voice-Line menu'.

Check power supply of SPA.

Regards.
