Hi.

I'm Dong-Il Yoon in KT.

I have a question about stream descriptor of MEGACO protocol. 

In 7.1.4 Media descriptor of H.248.1, there is a last sentence as 

" As a convenience, LocalControl, Local, or Remote descriptors may be included in the Media descriptor without an enclosing Stream descriptor. In this case, the StreamID is assumed to be 1."

I think that those sentense will not apply to megaco Command Reply message but Command Request message.

I mean, for example, if MGC send Add Request message with StreamID=1 then MG must response Add Reply message with same StreamID=1, and if MGC send Add Request message  without StreamID then MG must response Add Reply without StreamID.

In conclusion, last sentense in 7.1.4 , I think,  you mean that , as a convenience, MGC can omit Stream descriptor when the streamID=1, and then MG have to assume that streamID=1.

I am concerned that my analyse is right. 

I'm waiting your response.

Regards.
