Hi Manju,
Yes UAS should send 400 BAD request as From header should send only
one tag parameter. This tag parameter is used make Dailog-id which is
unique for one established session. So , if there are multiple tag
parameters then how UAS will decide which one to use.
Refer RFC 3261 for more details.
Thanks and Regards,
Vivek Talwar
