Automatic SMS replies Merged

We are a business and we have had some issues with people texting our main line. We would like to disable SMS messaging to our main line and some extensions. We would still like the options of sending SMSs in the future so we don't want to disable it permanently. The other thing that would be really helpful is if there was an automatic outgoing message to anyone who sends us an SMS. This will insure that people will know they can't text us but still provides our business information for those looking.
