Hmm that seems like a huge shortfall. 95% of our DIDs are port-ins. After clicking through a ton of random DIDs in our account I was finally able to find one with the option available, but it's not much good if it's available this few and far between.
What do you mean "bring your own number to" exactly? For Bria, is this what you're referring to?
Without building our own UI for SMS, I can't really see any point in using this nor do I see how it helps us 😕
