Ok, I just got back from the Cisco IPT training and had one question. I currently program on the Avaya platform and use the duplicate command daily to find the next available extension in our DID range for new hires. Now.........with the call manager how do you find an available DN?? We are planning on deploying a cluster to a site with about 2000 phones, and with people coming and going I am starting to wonder how will I find an available DN in a range of 4000 DID numbers??? Is there some sort of export that would give me all used DN's??
