A good experience would do both, in a comfortable way for either.

Continuing with the example, if you have a single phone number field, or 
let a mobile number be entered in a field marked for landline, you will 
probably assume you can text to that number.  I see this all the time on 
signups that are attempting to provide some sort of 2FA - I enter the 
landline number and the website tries to text a verification code to it 
(rather have an authenticator app for 2FA anyway, but that's a different 
argument)

Suggests maybe labeling should be something like:

* Number you want to be called on
* Number for texted security messages, if different

Never seen that, though :-)
