report ringing to the main system. A possible source of this problem is that the signaling method for the
DTIC is not set to the correct value. The signaling method is set in LSP Table parameter 24. If the
problem occurs, contact Technical Support.

This problem probably means that the setting of the DTIC as a clock sync source is not correct. If only

the clock rates may not be the same.
If more than one DTIC is configured in the system, check that the DTIC is configured as the primary
clock sync source and also check that the PBX is using the same clock rate.
