When an incoming call is arrived at the FXO interface of a cisco router, I want to get ringing at certain voip extensions. What IOS command could accomplish this?
And other than SJPhone, what other opensource/freeware softphones can be used with Cisco Gateway instead of Gatekeeper?
Will VoIP work between two satellite links which both of them have latency over 1000ms at each sites? What is the best codec to use for such situations?
