Hello. You’ve reached the establishment of Binder and Binder Law Offices in West Chapel. We regret we are not here to answer your call. However, your call is important to us, so please leave your contact information and a brief message at the tone, and we’ll get back to you shortly. It’s been a pleasure receiving your call.
What you do not want to do is say your phone number so quickly that the person has to listen to your voicemail multiple times to try and figure out your phone number. We have all gotten those annoying voicemail messages where the person said their phone number so quickly that we had to listen to their message several times to figure out their phone number. Don't be that jerk who leaves their phone number so fast that the other person has to listen to your message over and over to try and figure out what your phone number is.

Put some thought into your message before you hit “record.” It takes very little time to write a script for yourself to read as you record your greeting. Reading off a script eliminates unnecessary pauses, “ums” and “ahs.”
