The fact that your NEC PBX is changing the Call-ID between after it receives a 401 response to a REGISTER request is a problem with that PBX, not Asterisk. From RFC 3261, Section 184.108.40.206:
Note that when requests are retried after certain
failure responses that solicit an amendment to a request (for
example, a challenge for authentication), these retried requests are
not considered new requests, and therefore do not need new Call-ID
header fields; see Section 220.127.116.11.
