This is the main exchange at the SLSO. Typically the calls I get from this are solicitations: wouldn't I like to subscribe to a Symphony series this year? Was I aware that so-and-so was conducting next month?
This number has now called me 3 times in the past two weeks, but they never leave a message. If it is a non-profit organization, I don't understand why they wont leave a message unless they are trying to drum up sponsorship revenue.
