11.3 Defining Service Groups
Enter a Description for this service group. Then, move the individual services required for this group into the
new Service Group box.
When an outbound call is initiated using the Service Group, the services in the group will be tried in top-down
order until an idle service is found. The call will be made using the first idle service in the list. So, the last step
in setting up a Service Group is to ensure that the order of the services reflects your preferred priority of use.
When one of the services in the group is a SIP proxy, the SIP proxy will continue to be considered idle until
its Maximum Active Calls setting has been reached.
