Behavior Change
Previous Behavior: Earlier, deregCallbackUri was sent in the UDM Registration Request /namf-comm/v1/callbacks/dereg-notification/supi-xxxxxxxxxxxxx.
New Behavior: Now, there's a change in the existing deregCallbackUri sent in the UDM Registration Request. The new format is /namf-comm/v1/callbacks/dereg-notification/supi-xxxxxxxxxxxxx-xxxxxxx.
Customer Impact: There’s no impact, as the UDM automatically uses the new deregCallbackUri received from the AMF.
