 Hi All,

   I have a question on the use of H.235 Annex D (Baseline Security
Profile). According
to this profile, except for GRQ/GCF messages, all other RAS messages shall
contain a hash
value computed using HMAC-SHA1-96 algorightm on the entire RAS message.
Consider an
endpoint sending RRQ to the Gk. In the clearToken field of RRQ message, the
endpoint shall
fill generalId as gkId (which it got in GCF) and senderId as it's own epId.
EpId is
generally returned to the endpoint by the gatekeeper in RCF. That means that
an endpoint
may not have an epId while sending RRQ to Gk. In such a case, how it is
supposed to
fill the senderId and compute the hash value on complete RRQ message?
Any pointers are appreciated.

Manoj Paul.
