I am currently having trouble letting callers go out internationally. It has been working in the past and not sure what has changed. No matter what country is called we get a fast busy signal after the numbers are dialed. It lets us dial all the number with no error. I checked and i cant find anything wrong with our dial peer or call manager. I am using RTMT and its giving me a code of 27 destination out of order. We are using cucm 9.1. I hope this is enough info and i thank you for any help.
