we try to rebuild a sentry fuunctionality for a customer of us migrating to online.
Some contact fields have to be read only for a contact imported from ERP.
If I try to use Sentry Preference for it,
it functions with department and address (all the address fields are readonly), but not for the phones.
I can't find a example to set phones and faxes for a contact readonly. What would be a proper preference for it?
Thank you in advance!
