I have an outbound route that has "destination_number" set to "^\+?1?(\d{10})$". Twilio will only process numbers in E.164 formatting and they provide this regex on their site "^\+[1-9]\d{1,14}$". I've tried many "destination_number" regex expressions (including Twilio's) but to no avail. I've also tried dialing the nuimber differently i.e. using country code not using country code. Again, to no avail. What do need to set to make sure numbers get formatted correctly? Thank you!
