blocking sms to phone line?

sometimes, when I get a call & can't answer- I send quick response like "I'll call you back"
but, sometimes the call is from line phone and than

1. the sms doesn't reach the other side
2. my cell company charges me extra for sms to line phone

is there a way to tell android (5 or 6) not to send messages to phone numbers that start with 0x or send messages only to numbers that start with 0y?

thanks
