Multi-Factor Auth using Voice Messages + Twilio

Ready to post? :magnifying_glass_tilted_left: First, try searching for your answer.
A client has requested that there are customers who do not want to user their cellphone to receive verification codes. These users would rather prefer to receive voice messages on their work landlines.
My question is can these users receive voice verification codes when the corporate landlines have extensions? Can this be configured when using twilio setup in MFA settings?

Hi @rishabh.ohri,

Welcome to the Auth0 Community and thank you for your post.

When it comes to Auth0, the phone extension option is not yet available, as mentioned in this community post, but it is part of our Product backlog, so it should be coming up rather sooner.

After my research when it comes to implementing Twilio with Auth0 MFA, they do not provide a solution out of the box for this use case. However, you might be able to integrate a workaround such as by taking advantage of their Interactive Voice Response system.

I hope this helps your better understand and the case.
Thanks,
Remus
