Dear Mike,

I checked H.245 V.3 from a security point of view and found out that the
following issues have to be corrected:



Subsection Conference Response definitions is missing definition of
ReturnSig which should be as follows:

ReturnSig ::= SEQUENCE {
 alias   AliasAddress,
 responseRandom RandomVal,
 requestRandom RandomVal OPTIONAL,
 certificate  TypedCertificate OPTIONAL - requested certificate
}
EncodedReturnSig ::= TYPE-IDENTIFIER.&Type (ReturnSig)




The following definition seems not to be used by any H.245 ASN.1 and
looks rather redundant; thus it should be removed:

ChallengeString ::=OCTET STRING (SIZE(8..16))



Please incorporate these changes to the text. Thank you.

Martin.
