Hi Sourav,
The URI is not used for matching in 3261. So, in order to have better
interoperability, you should limit to matching the fields identified by 3261.
Thanks,
Neel.
12.2.1.1 Generating the Request
A request within a dialog is constructed by using many of the
components of the state stored as part of the dialog.
The URI in the To field of the request MUST be set to the remote URI
from the dialog state. The tag in the To header field of the request
MUST be set to the remote tag of the dialog ID. The From URI of the
request MUST be set to the local URI from the dialog state. The tag
in the From header field of the request MUST be set to the local tag
of the dialog ID. If the value of the remote or local tags is null,
the tag parameter MUST be omitted from the To or From header fields,
respectively.
Usage of the URI from the To and From fields in the original
request within subsequent requests is done for backwards
compatibility with RFC 2543, which used the URI for dialog
identification. In this specification, only the tags are used for
dialog identification. It is expected that mandatory reflection
of the original To and From URI in mid-dialog requests will be
deprecated in a subsequent revision of this specification.

Subject: [Sip-implementors] From Header value is getting changed from 100
trying to 200OK
Hi, I just need clarification is the below mentioned scenario will work
properly
UAC1 sending INVITE request to UAS1
----------------------------------------------------------
From: "+351964901478" <tel:+351964901478>;tag=AUA401YVCeghCjaA
UAS1 is responding 100 Truing for that INVITE to UAC1
--------------------------------------------------------------------------------
From: "+351964901478" <tel:+351964901478>;tag=AUA401YVCeghCjaA
UAS1 is then sending 200OK for that INVITE to UAC1
-------------------------------------------------------------------------------------From:
"+351964901478" <tel:1478>;tag=AUA401YVCeghCjaA
All other header are prefect.So is UAC1 send ACK for this? Or UAC1 ignore that
200OK due to the change in From header value?
Thanks & Regards,Sourav
