I thought Id put together a diagram on how a call flow works from an external call to an internal extension. In this case, I have a Cisco CUCM in place, with a Cisco voice gateway as the interface to the Telco. Telco provides a PRI to the gateway.
This is the retired Shane Killen personal blog, an IT technical blog about configs and topics related to the Network and Security Engineer working with Cisco, Brocade, Check Point, and Palo Alto and Sonicwall. I hope this blog serves you well. -- May The Lord bless you and keep you. May He shine His face upon you, and bring you peace.
