Try blocking some time for communication today.  Here is your voice mail.  “It’s a great day at the Sanford Team’s office and we will return phone calls from 11AM-12Noon and 3:30PM-4:30PM.  Please leave your exact need and the phone numbers where we can find you during those times and we believe we will be able to handle your needs prior to our guaranteed same day return phone call. ”  Now time block the times, tell your family, staff and clients this is the new method to guarantee that everyone is helped and stick to it.  Soon, you will have most people trained to just call during those two hours.   In those two hours handle all incoming and outgoing email, all incoming snail mail and all incoming and outgoing phone business.  You will find almost an hour a day not dealing with interruptions, be happier and have happier clients.  Now spend that hour generating some seller leads.
