Calls are 30% of the time working over a trunk group I have set up. I am a voice noob and have been told this may be a clocking issue. I am unsure how to check this.

DS0 Dial Out Trunk Groups can be provisioned for dial out only at present and should not be provisioned as targets of dial-peers. DS0 trunk group configuration and conventional trunk group configuration are mutually exclusive. Conventional trunk group configuration is done in the serial interface mode and places all DS0s in the PRI into the trunk group.

clocking hierarchy (in case the primary source goes down):
