You can use this app to receive voicemail and missed calls on your email. Provide your callers a great calling experience. It also allows you to withdraw the sent voicemail.
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.

Many callers will be respectful of your wishes and follow your directives. This is extremely vital for reducing your voicemail volume.
The next key element is giving a short reason or apology for being unable to take the call. Make sure to say something quick and concise like: “We are sorry to miss your call, but we are assisting others or away from our desk.”
