Having an issue calling international. According to AT&T the T1's need to be set for speech 3.1 audio and I don't see any such settings on the Call Manager. The T1's are connected through a Cisco box using CMM blades.
The problem is only calling a certain number using an Iridium (special stalite)phone. The problem isn't specific to the Call Manager. It works from another location that has an Avaya system. According to T&T it has somthing to do with 3.1 audio setting.
