I am having issues with one of our client. We have some analog lines mapped with same number and terminated on voice gateway. When somebody calls from outside the Operator phone rings but it gets dropped as soon as it is answered and the strange thing is that the caller continously hears the ringback tone.Configuration is as below
voice-port 0/0/0

no battery-reversal
