I have a production app working and it can send outgoing sms messages form all my numbers properly, except from my main company number. I have search around the forum and found several references that state that you have to use the operator extension that is defined in your IVR - which I am doing. But i am still getting the "Phone number doesn't belong to extension" error message returned.
Is this a possible problem with Multilevel-IVR? or does anyone know of a possible other issue that I may be missing.
