Description (partial)

If CUBE receives a TCS (like an empty-capability-set signal for a hold/resume transition) right after sending an OLC and without having received an OLCack or OLCrej from the other end; the CUBE will throw and error and wait until the timeout for the outstanding OLC shoots.

An error like the one below will get printed if running cch323 logs:

Jan 22 20:03:58.926: //79205/8010A5CB0400/H323/errHdlr: ERROR: Received Unexpected IWF_EV_CLC_IND in state IWF_OLC_AWAIT_EST_CFM
