Twilio - SMS mask my twilio number (from) with a non-twilio number

Question

I have some 1-800 numbers - not hosted on Twilio - that I want to use as the "from" number for an sms app I am building using Twilio. Is there a way to mask the Twilio number with one of these non-Twilio numbers so that the text message appears to be coming from the non-twilio number?

Example:

1. My app sends text to customer using the Twilio number as the "from" number.
2. Twilio masks the Twilio number so that it appears that the text came from the 1-800 number.
3. Customer can respond via text and it will route back through twilio and not try to send a text to the 1-800 number.
4. If customer tries calling the number back, it will NOT route back through Twilio, but actually call the 1-800 number.

FYI - the 1-800 numbers are VoIP numbers and therefore cannot use the new hosted sms functionality built into Twilio.

Answer 1

You can indeed Toll Free numbers (VoIP) hosted numbers on Twilio, VoIP numbers are supported. Open a support ticket with Twilio about hosting these numbers.

You cannot use non-Twilio numbers as the From for outbound SMS. Verified CallerID only works for Voice calls, not SMS.
