This telephone number (+14122532956) is my Google Voice number. Google Voice is a smart forwarding service that will allow me to ring different phones based on the caller. More information about this can be found in Call Handling. While I could technically receive SMS messages through this number, I only check for such messages during the times I check my email.
Since this number is public, I am OK with people giving this number out. With that in mind – I do have some conditions on certain calls from out of the +1 412, +1 724, and +1 878 area codes as most of such calls outside of the area code are typically scam or SPAM calls.
