Aseem, Paul and all,
LogicalChanelRate SDL should be very similar to any request/response pair like Paul mentioned. This was an Intel contribution for controlling video/data channel bitrate. I will consider bringing a clarification contribution to version 6 maybe and the implementers guide in an upcoming Rapporteur meeting. Yes releaseComplete should have a cookie to address the active SDL. I didn't want to deviate from the legacy :). I will address this issue as well. Thanks for the reminder. regards,
Hani

Aseem,
Good point. Looks like an oversight. Using the other signaling entities, or SEs, as a guide, it appears that when there is a single SE per call, as is the case with CESE, no other information is required; however, when there can be multiple SEs per call, as is the case with CLCSE, RMSE, _and our "LCRSE"_, one must identify which instance of the incoming SE in the remote EP is being released.
As a practical matter, I would say that upon receipt of LogicalChannelRateRelease as it is currently defined in H.245v5, an EP should release _all_ incoming SEs. At the earliest opportunity, we should add a logical-channel-number extension addition to this message, i.e.,
LogicalChannelRateRelease ::=SEQUENCE { ..., logicalChannelNumber LogicalChannelNumber }
BTW, If we had gone to the trouble of defining an SE for these messages, I bet this oversight would have been caught in time.

hi Paul
A related question. There are no "sequence number and logical channel number" information elements in LogicalChannelRateRelease message. How will a receiving entity correctly associate this message to the request message received earlier in case multiple such requests are pending ?
