We have a partner that would like to use Twilio for phone notifications. The problem is that our phone notifications are Talking Tech-centric, and the way our TT is engineered is odd to say the least. We specifically don't create the notices in Koha, but have TT create them instead. I think it would be good to have a system preference that allows phone notices to act in a 'normal' manner so to speak much like email and sms notices. Future outbound calling systems could then just be plugins that handle phone notices while Koha handles email and sms.
