Hi,

This email is regarding a clarification needed about a document submitted 
to SG16(SG 16 - Delayed contribution 284).

In the Document titled "Update on AMR speech codec support for H.245", 
Table X.4 a parameter "octetAlign"
is mentioned. But the same is missing from the latest H245 formal 
specification.

As per the document(Delayed contribution 284),  "octetAlign" parameter can 
be used to specify
whether the bandwidth efficient or Octet aligned mode of operation is used.

Since, In the formal spec, this parameter is missing, how should we 
negotiate whether
we want to use Bandwidth efficient or Octet aligned operation.

I also see other parameters(modeSet, ModeChangePeriod, ModeChangeNeighbour, 
Crc,  robustSorting and interleaving)
mentioned in your document, but are missing from the formal spec.

Any information about how to negotiate those parameters?

Thanks
Venkata
