I need some help with a FXS port config connected to Cisco 2821 gateway
I have configured MGCP for communication between CUCM and the Gateway. I have an annalog phone connected to a VIC3-4FXS-DID and the port is configured for ground Start. I am able to receive calls on the phone from an IP Phone , however I am not receiving a dial tone from the analog phone.
Call Manager version 7.1.3
