Here is a scenario that I need everyone’s thought on this. I
have two Networks. Network “A” and Network “B”. Users at Network “A”, when they dial a phone number, it takes an interval of about 5 to 6 seconds before the phone actually starts ringing at the receiver's end. While users at Network “B”, the receiver rings instantaneously after the same number is dialed. I am not sure the causes, but my basic understanding on switch configuration is telling me to focus on egress and ingress settings on the switches but I honestly don’t know where to begin. Any thought or help will be highly appreciated.
