<@1145576664366055464>  We are using a Twilio-owned Netherlands (+31) number imported into Retell.
In our current setup, live call transfers to another Netherlands number fail with a permission error.

Can you confirm whether live call transfers to NL numbers are supported today when using custom telephony with Twilio (Twilio originates the outbound leg), or whether this is still restricted regardless of number ownership?

If supported, what specific Retell + Twilio configuration is required to ensure Twilio (not Retell) initiates the transfer?
