Whoopee, a call. I wonder who this could be? No…wait…don’t tell me…Oh yeah. Sorry, you bore me.
Just press the button and you’re on to the next call while the software is recording your pre-recorded voicemail on the other line. Be sure to plan and practice your message. You want it to sound natural and enthusiastic without seeming overly excited or solicitous. You also want to make sure it doesn’t go on too long.

You don’t have to spell out every single thing that you think they might want to know. Have some faith that your callers will be able to figure things out on their own. Be natural but informative.
Of course, we want to know as soon as an incoming voicemail is saved, so again, it’s Twilio to the rescue. By adding a few lines of code to our Python script, Stacey and I each get an SMS notification telling us there’s a new message. Note that Twilio’s API requires a separate call for each message to be sent, which is why the similar code repeats once for Stacey’s phone number and then again for mine. If you plan to send bulk messages from Twilio, I expect that you can build a list of phone numbers and loop through them with the API call. Since we only have two contact numbers and don’t expect to add any more, I decided not to loop through a list of two elements.
