[cisco-voip] is all traffic endpoint initiated?

[Lelio Fulgenzi]

Thanks Ryan, 

Our plan was to: 

    1. install the new publisher using DMA with a new IP address on a new VLAN 
    2. reconfigure callmanager groups so they all use the publisher and only the publisher 
    3. delete call park numbers on all subscribers 
    4. remove all previous subscriber information from the new publisher 
    5. start installing the new subscribers 
    6. rebuild callmanager groups and call park numbers 

I'm not sure how I can do that on a dead network, since the install process goes out and does DNS tests and NTP tests etc. Plus I need to access my DMA upgrade file too, right? 

I guess I could skip enabling DNS, NTP, etc, until just before step 5 once I put the publisher on a live network, and perform steps 1 thru 4 on an isolated VLAN with SFTP access to my DMA file? 

What do you think?

The CUCM servers themselves initiate connections to each other and I have seen post-DMA servers initiating connections (SDL, media resources) to the 4.x servers because they were reachable. I'd highly advise keeping your post-DMA servers on a dead-net until you can get new IP addresses on them.

We are planning on building a new 7.1 cluster using DMA. I want to make sure that we don't cause any service interruptions in our production network. Can anyone confirm that any traffic, i.e. registration is end point initiated? We only have SCCP and MGCP and SRST devices out there. There's no reason for the new cluster to try to talk to any of the devices out there is there?
