Will BT advanced phones conect to vodafone router via WPS?

[Bigbill2656]

I have a full Fibre set up but my router will not pick up my Advanced Digital handsets? I know they are DECT does a vodafone router support DECT. I have pressed the WPS button and the phones dont connect. I have also tried taking my ipone off my network then pressing the WPS on router. on my wifi listing on my ipone the original Vodafone router shows but it askes for the password even when i have pressed WPS? 

thanks if anyone can advise me.
