error in installing kazoo in centos 6.4

[Nithya M]

I am trying to install kazoo in centos 6.4
error in ecallmgr


[root@test ~]# /opt/kazoo/utils/sup/sup -n ecallmgr ecallmgr_maintenance allow_s                                           bc $FQDN $KAMAILIO_IPConnection to service failed!
Failed to connect to service 'ecallmgr@test.2600hz.com' with cookie 'some_cookie                                           '
  Possible fixes:
    * Ensure the whistle service you are trying to connect to is running on the                                            host
    * Ensure that you are using the same cookie as the whistle node, "./sup -c <                                           cookie>"
    * Verify that the hostname being used is a whistle node



help me to solve this
