Destination Server-Groups Server-groups give administrators the ability to configure multiple destinations (session-targets) on the same VOIP dial-peer. By default, the sort order is the preference defined in the server-group entries. Round-robin hunting can be employed when you use the command hunt-scheme round-robin. Server-Groups were added in Cisco IOS 15.4(1)T and Cisco IOS XE 3.11S. In Cisco IOS XE 17.4.1a configurable huntstop error codes was added to voice class-server group configurations.
