This read-only OCTET STRING reports the called party number for this leaf, applicable if this leaf is an SVC, i.e., the destination address that was dialed to establish this leaf's connection. This lets an admin confirm which target address a dynamically-established leaf was actually signaled toward, useful for verifying that call routing directed the leaf to the intended destination rather than a misdialed or misrouted address. An engineer diagnosing a leaf that connected to the wrong endpoint would compare cktLeafSvcCalledParty against the expected destination address to confirm a call-routing misconfiguration.
