Claim record · CUCM CDR and CMR field reference
For on-net call legs Unified CM determines the cause code value and for off-net legs the far-end switch determines it, so a cause on an off-net leg is a foreign network's statement carried through rather than Unified CM's own diagnosis.
fact · verified 2026-09-15
For On Net call legs, the Unified Communications Manager determines the cause code value. For Off Net call legs, the far-end switch determines the cause code value.
