1. To configure redundant config server..example is shown below


2. 2nd...Yes the Ip addresses are the servers used for call processing. Depending on whether your publisher is performing call processing, you can put the 2 ip addresses, the first ip will be the primary call secondary server and the 2nd ip will be the 3rd processing server.


This will be like this in your ccm-group

server a

server b

server c


where server a is ocnfigured in your mgcp call agent config as follows:


mgcp call-agent 10.176.105.1 2427 service-type mgcp version 0.1


and server b abd c are configured as shown in the ccm-manager redundant host section



ccm-manager redundant-host 10.146.90.200 10.146.200.200

ccm-manager mgcp

ccm-manager music-on-hold

ccm-manager config server 10.126.5.200 10.127.7.80

X.X.X.X = TFTP Server (in most cases same as the publisher ip address)


Y.Y.Y.Y and Z.Z.Z.Z = both backup Cisco CallManager servers = Subscribers

Got it and thanks. More question,

1st If I have 2 tftp servers for redundance which located in 1 publish and 1 subscriber, so how to config 'ccm-manager config server X.X.X.X', if only one can be configed , how to Fault Tolerance.

2nd 'ccm-manager redundant-host y.y.y.y z.z.z.z' , I think these 2 address is the server which Call Process service located. Am I right? Or If I have only 2 CCM (1 publish and 1 subscriber), and both running Call Process, should I put these 2 ip add(Pub and SUB) here?


Thanks in advance
