Hi,
We are testing
the REGISTRAR with kamailio.
We tested the
following scenario ,
è Register Request with contact ‘A’.
è 200 OK received for the request
è Second Register request with contact
‘B’. (Requet-URI, To Tag, From tag, call-id, and Cseq ->
all same as the first register request)
è 200 OK received for the request.
When we checked
the ‘location’ table entry, two records were found for the
same user with different contact addresses.
Please find
below the RFC extract below,
Section
17.2.3
For all other request methods, a request is matched to a
transaction
if the Request-URI, To tag, From tag, Call-ID, CSeq
(including the
method), and top Via header field match those of the request
that
created the transaction. Matching is done based on the
matching
rules defined for each of those header fields. When a
non-INVITE
request matches an existing transaction, it is a
retransmission of
the request that created that transaction.
My
understanding is that the second register request should be
considered as duplicate and rejected.
Please share
your feedback on the same.
Regards,
Shankar
