I know this is an easy question but I'm drawing a blank. I've got a cisco 1861 on IOS 12.4(20) and I'm setting up the FXO ports now. The system works except one issue - when a caller calls inbound to the system but hangs up before someone answers, the 7961 phone still rings. I'm sure it's a problem with the configuration of the voice port but need a little direction. Here is the setup of the port:
connection plar 1001
Any help is appreciated.
