NotEnoughChans
Call attempt was rejected because requested gateway channel(s) could not be allocated. Some of the
more common reasons for the lack of channel to place outgoing calls include: High call traffic volume
that has the B-channels in the device fully utilized; B-channels have gone out of service for the following
reasons: Taking the channel out of service intentionally to perform maintenance on either the near- or
far-end; MGCP gateway returns an error code 501 or 510 for a MGCP command sent from Cisco Unified
Communications Manager; MGCP gateway doesn't respond to an MGCP command sent by Unified CM
three times; a speed and duplex mismatch exists on the Ethernet port between Unified CM and the
MGCP gateway.
