A voice call always travels between two virtual interfaces. The configuration of the two virtual interfaces is used to determine the media services and logical router interface that should be used by the call.
To create a virtual interface and configure the media service and the logical interface (that is, a specific unit on a physical interface), include the virtual-interface statement at the [edit services pgcp] hierarchy level. Note that the routing-instance option is not supported in this release.
