Adding IVR functionality to your Android Phone is useful for:
- users who wish to use a locally-masked caller ID.
- users in countries where Twilio doesn't sell phone numbers that allow for inbound calls.
- users who wish to use a local phone number Contacts can text or flash*.
*Having a contact call your number and hang-up with the expectation you'll call them back (the caller picks up fees while it's free to receive calls). Useful in the absence of a toll-free number.
To enable IVR functionality on your Android Relayer, you'll need to sign up for a Twilio account. Twilio's TwiML API will handle outbound calls, while the Android Relayer will handle inbound and outbound SMS messages.
Use your Twilio account to verify new outgoing caller ID numbers. To use your dashboard, log into your Twilio account and visit the Phone Numbers tab. Click the Verify a number button at the top of the page.
Twilio now imposes International Voice Dialing Permissions on each new account. You'll need to complete a request form to call countries not listed on this page (must be logged-in to your Twilio account to view). Please follow this link to apply for international voice dialing permissions.
