CallId/ConfId in LRQ

Hi,

Presently, when a GK needs to resolve some aliasaddress, it sends LRQ to another GK which has a co-located Border Element (BE). This BE may need to generate an Access Request (according to H.225 Annex G), to another BE. It might be mandatory for the requesting BE to include callInformation (callId/ConfId) in this Access Request (depending on the address template it holds). But LRQ message does not have a callId field in it. How can the requesting BE then derive callInformation for Access Request message? Any help will be appreciated.

regards Manoj.
