Map Circuit Identification Codes (CICs) to trunk groups and voice circuits. Ensure alignment between Signaling Points (SPs) for successful call setup.
Generate a CIC range map for your trunk group configuration.
The Circuit Identification Code (CIC) is a 12-bit or 14-bit field in the ISUP message that identifies the physical circuit (timeslot) being used for the call. Misalignment of CIC mapping between switches is a common cause of single-way audio and call setup failures.
