I have a scenario where there are five subscribers and one publisher call manager.If subscriber A's connectivity to publisher breaks, utils network connectvity in sub A fails with publisher, can a phone registered with sub A make and receive inter and intra cluster calls?Here calll manager services are disabled on publisher so will it have any effect on call routing outside and inside cluster?
I am going to assume that there are no devices registered to the publisher server as you said.
I couldn't understand your question exactly, so i will answer the question for two scenarios.
1. If the publisher server went down and all other server are still online and have connectivity to each other: call processing will not be affected.
2. If one subscriber loses connectivity to the other servers, but still has connectivity to the devices registered with it(for example: the server is located over WAN and the WAN goes down): calls will work only between devices registered on that specific subscriber.
Hope that helped.

Thanks a lot Nomat . You cleared most of my doubt .You were absolutely right that no phones are registered on publisher.
WAN of Subscriber A to publisher was intermittently down. Secondly, on command line interface of subscriber A , utils network ping Publisher ip was successful but utils network connectivity command gave the output that "Test failed.Could not send/receive UDP/RDP packets to the publisher".What is the function of this comand?
However, the publisher could be pinged from subscriber A and all other subscribers.Now what would be the effect on call routing intercluster/intracluster from the phones registered to subscriber A ?Should it beable to call phones registered on other 4 subscribers?Also, do the subscribers communicate to each other directly or only through the publisher?What is the effect of publisher going down?Please explain the communication between all the nodes , what data do they exchange and what is their keepalive?
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
