Once this is entered into the phone via the keypad they reset back to factory defaults.
I have no idea why this is happening and it is driving me nuts. The phones are on 2 different sites and I have to travel to the other site to re-configure these phones after they have factory reset.

Hi,

Not sure if this is the case but I think your phones are locked to some providers RPS.
Did you buy them from Amazon or other 3rd party reseller or directly from a Yealink reseller?

Kind regards,
Frank.
