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.

thanks Manoj Paul.
