NOTE: Transcriptions for recordings are a paid feature. Your account will be charged if you use this service.You may want your phone number to forward to another number, and yet sometimes you may want it to directly send a call to voicemail. The caller can leave a voicemail which will be transcribed and emailed to you. Follow these steps to set up the voicemail forwarding within Twilio:
Under Settings > Phone Numbers leave the "Call Forwarding" number blank.
Log in to your Twilio account.
In the Dashboard on the left hand side, navigate to “Develop” and “TwiML apps”
This is where you can build little apps within your Twilio.
Click “TwiML apps” and in the new tab that opens, click “Create new TwiML App” at the top right.
In the popup, add a "Friendly Name" for the voicemail.
Fill out the Voice and Messaging Configuration.
Click “Create” to complete.
Navigate back to Develop > Active Numbers
When a call comes in, the default should be a webhook that reads a default Twilio message. You can update this and change it to the TwiML Bin you just created. Update this to "TwiML Bin" and choose the name of your voicemail you set up.
Click save in the bottom left.
NOTE: We recommend that after setting this up, you call the number to test it. When you dial the number, you should be directed to the voicemail, and it should speak your message in the voice you chose. Leave a message, and it should be transcribed and emailed to you.PRO TIPS:
In order to generate a transcription from a call recording, use the <Record> verb in your TwiML and set transcribe=”true”.
The max recording time is 2 minutes in length.
