I am not sure what you mean. You need to block calls to your land line from cell phones only? I don't think it's possible. You can call your phone company and ask them to block a particular phone number (for a fee), or you can buy one of those devices that let you block calls from 'unknown' numbers. Another option is to find out who calls you and ask them to stop. You can enter the number that calls you at 800notes.com, http://800notes.com , to see if other people have reported calls from it. If yes, then you might find our who the caller is and how to stop the calls.
To avoid unnecessary calls from telemarketers, register your number in the "do not call registry list" and to avoid the unnecessary calls from unknown numbers use call barring system and block those numbers.
This can be done via the Boost website. There will be a prompt to enter the mobile number from which one wishes to view the calls, followed by a request for the passcode. This will enable the user to view their incoming calls from the past month.

To block text messages but allow calls from a specific number, you can use your phone's blocking features. On most smartphones, go to the messaging app, find the contact you want to block, and look for an option to block messages while keeping their calls enabled. Alternatively, you can check your phone’s settings under "Block numbers" or "Do Not Disturb" to customize which contacts can call or text. Keep in mind that the exact steps may vary based on your device's operating system.
