Hi Ram,

SylkServer doesn't seem to like the SUBSCRIBE request you are sending, hence the 400 response. Also, the 403 seems to be the pyload of the NOTIFY, that is, the response code that the generated INVITE (not shown in the diagram) got. Can you please share a SIP trace for this scenario? You may send it to me privately if it contains sensible data.
