Usage guidelines
Dynamic call mode: When a call is originated, the frame relay will randomly select an idle FRF.11
sub-channel to establish a voice channel. After the call is completed, the frame relay will immediately
remove the voice channel and release the corresponding FRF.11 sub-channel. The call control protocol
used in the dynamic call mode is specified by executing the vofr command in interface DLCI view.
FRF.11 trunk mode: A voice channel is established when you execute the address vofr-static command.
The voice channel is directly used to establish calls. After the call is completed, the voice channel remains
until it is manually cleared. In the FRF.11 trunk mode, you must use the trunk-id command to configure a
PSTN-dialed number for the terminating VoFR entity.

# Configure the FRF.11 trunk mode for VoFR entity 10.
