Verify network connectivity.
Verify IP address of the CTMS configured on
Unified CM SIP trunk.
Verify the that static number being dialed is a valid
number.
Verify that SIP Trunk security profile "Outbound
transport type" is set to "UDP."
Verify that all Unified CM servers are entered in
Unified CM settings.
Verify that the CTS endpoints numbers are entered
correctly.
Verify that rooms are available.
Check the registration status of the CTMS on the CTM
page.
Verify that the scheduled meeting is listed on the CTMS
(under Scheduled Meetings).
Check to see if there are sufficient ports. Unified CM
delivers a "Service not available" message when CTMS
places a call to CUVC and there are an insufficient
number of ports available.
Verify the number dialed for the CUVC connection is
defined to Unified CM as a SIP trunk, and is correctly
configured.
