Re: debug result

“Mandatory information element missing” indicates that the equipment sending this cause has received a message which is missing an IE that must be present in the message before the message can be processed.

Channel is always mandatory in the first response we receive from the peer. But, for the user-side, some implementations allow user not to respond with a channel-id in which case network-side need to assume the channel that was sent in SETUP.
