Hi I have a customer who has analog lines going to a dialer panel for an alarm control system. Some calls come in and connect fine while others intermittently fail..looks like they dont get answered when the Adtran sends the call.
i have pasted my voice use configs etc below. If anyone can give me an idea why some calls work and others fail I would greatly appreciate it.
