This log indicates that an attempt to bring up an additional trunk
failed due to the lack of an unoccupied, configured trunk.
This could cause the failure of a voice call depending on the media
allowed to communicate to that remote, the priority of the call, and
the Extra Bandwidth configured.
However, verify the presence of log number 55 on the RLC to see if
a voice call did not succeed. Look for the presence of log number
37 on the RLC. It indicates that an attempt was made to connect
the voice call on that medium, but that the medium was not
reachable.
