ESA50 - how to indicate - no contact by phone

Hi

I'm currently re-applying for my ESA using the ESA50.
Could you clarify you current advice regarding supplying phone numbers.

Your ESA/UC guide, p75 - face-to-face states:

'If you have a mental health condition as well as a physical one and you would find it difficult to speak to someone on the phone to arrange an appointment, then consider not giving a phone number and instead explaining in the box that, because of your mental health condition you need them to write to you rather than phone'.

However the current ESA50 p19. - Face-to-face Assessment - no longer has a box requesting a phone number in that section, only a 'Tell us about any other help you might need in the space below.'

Meanwhile there is now a box to enter a phone number on ESA50 page 2 called 'A phone number we can contact you on'.
Additionally on ESA50 page 1, a final bullet point states 'Make sure you fill in the 'About you' section on page 2 in full.' suggesting all boxes on ESA50 page 2, - About You - might be compulsory and so supplying a phone number is no longer an option.

Could you therefore please advise how to indicate a preference for not being called without violating the conditions of filling in the form as it exists today and in relation to ESA50 page 1,2, and 19 ?

Many thanks for your time and attention. appreciated.
