© 2006 Cisco Systems, Inc. All rights reserved. CVOICE v Summary The connection plar command permanently associates a voice port with a specific telephone number. The voice port does not present a dial tone, but automatically generates the configured number. The connection plar-opx command provides far-end answer supervision to the local PBX from the originating router. The PBX does not see the call as completed until the far-end router answers. The connection trunk command establishes a two-way, permanent trunk connection between two PBXs. Supported signaling is E&M-to-E&M, FXS-to-FXO, and FXS-to-FXS. The connection tie-line command emulates a temporary tie-line trunk to a PBX. A tie-line connection is automatically set up for each call and torn down when the call ends.
