OPTIONAL perCallInfo Fields (Q12)


The information in this article applies to: H.323, H.225.0

The Recommendations are silent and there is no consensus as to the meaning of a missing value for the OPTIONAL audio, video, data, h245, and callSignaling fields of IRR.perCallInfo. IOW, the absence of a value does not necessarily mean that there are no channels of this type. The sender could have simply chosen not to provide information about them. This, unfortunately, makes these fields almost useless to a receiver of IRR.
