Of course, your phone rang because someone wanted to get in touch. They got your voicemail because you were busy or just not there. If you section off a block of your day to check voicemails, let the caller know so they can expect a time for you to return their call. People will leave more details if they know someone will check it later.
With all of the libraries installed and the Python code modified, our app is ready to accept calls and record voicemails. But it can’t quite do that just yet. There’s one more step: Twilio actually needs to know where on the internet the Raspberry Pi is running. Since this is a local server, that’s a bit tricky, but there’s a simple solution called Ngrok.

What kind of business phone service does your company use? If they haven’t been updated recently, or you haven’t made the switch to a higher-end VoIP phone that typically offers better sound quality, it’s time for an upgrade. The equipment you use can make all the difference. At the end of the day, people are judging your business based on little things like that.
Using your cell phone to record a voicemail message isn't always easy. Between remembering what to say and getting the right timing, it's tricky. But your phone does have a playback option, and it's easy to listen to and review your message. For some people, though, cutting off the end of a message is a funny way to trick people and catch them off guard. In most situations, callers won't know it's intentional and will think you're far less than tech savvy. Definitely not an impression I'd want to make.
