I have got a situation that I need to do a fail over server. I need to know the ristrictions and advantages. I need to know the steps to make this happen. I can not find any reference to this in the Unity documentation.<br><br>Sean Poure<br>NEC-Voice Engineering<br>Sr. Systems Engineer<br>714 4846275<br>
Jeff, I still don't understand. In case of PBX same thing as you said. TWO MCI link with PBX. Correct me if I am wrong here. Unity back up server has no intelligence to keep ports on stand by. If on Primary the ports are all busy the next call will go to backup server regardless if primary is down or up. All fail over does is to replicate prompts and greetings using NT replication to the backup server. Of course by joining the same location Unity will share some stuff with primary Unity . As far as port availability goes in case of 8 port system it is just disabling the 4 ports on a Unity. The other 4 will answer. Once you enable the first 4 port(bringing the primary on line in my example) calls will go to first port again. Please verify if I understood it correctly

Well I am no Jeff, but let me take a crack at some things here.
"If on Primary the ports are all busy the next call will go to backup server regardless if primary is down or up"
That is correct. As long as all ports are in the same hunt. Or if the roll-over from the last port of first hunt is the first port of the second hunt.
"As far as port availability goes in case of 8 port system it is just disabling the 4 ports on a Unity. The other 4 will answer"
That is correct. Disabling the ports in the SA will cause them not to answer.
"Once you enable the first 4 port(bringing the primary on line in my example) calls will go to first port again."
Well it depends. Simply disabling the ports on the SA has no control over whether the switch is going to sends calls there or not. This would be the case with either legacy or IP integration. The disable simply makes the ports not-answer. It does nothing for taking the ports out of service on the switch. If in a simplified hunt scenario, the switch is still going to send calls to the SA disabled ports, they just won't be answered.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
