Status Code Description
SIP - Request Packets
2002 Invite Indicates that the client sends a invite request for a call establishment to the SIP server and waiting for the response from the SIP server.
2004 Cancel Client can ask the SIP server to cancel a request which it sends previously
by sending Cancel request. (Ex. Client can ask the SIP server to cancel a call INVITE request which it sends previously for a call establishment by sending the CANCEL request.)
SIP - Registration Requests
1010 Registering The Registering status states that the client has requested the SIP registrar for registration and waiting for the response from the SIP-Registrar.
1011 Registered Client is registered with the SIP Registrar
1012 UnRegistering The UnRegistering status states that client has requested the SIP registrar for unregistration and waiting for the response from the SIP-Registrar.
1013 UnRegistered Client is unregistered with the SIP Registrar.
Other Codes
999 Active By receiving the OK packet for the Invite request, the call is moved to Active state.
1000 Completed By receiving the SIP-BYE packet(call tear down packet), a call is marked as Completed call
8000 Marked as Unmonitored By User If the user manually marks the active calls to the Unmonitored state(using the 'Mark as Unmonitored' button in the 'Active Calls' list, these calls will be moved to the 'Unmonitored calls' category)
8001 Unmonitored due to Server Restart If the VQManager server was re-started, the calls which were in the active state at the time of re-start will be grouped in the 'Unmonitored calls' category.
8002 Unmonitored due to Sniffer Restart If the Sniffer was re-configured manually while some calls were active, then these active calls will be grouped in 'Unmonitored calls' category.
8003 Unmonitored due to no media transmission If no signalling packets were received by VQManager for a certain time interval then the call would be moved to the 'Unmonitored calls' category.
8004 Unmonitored due to licensing In concurrent call based licensing, if more calls are initiated at the same time and the number of active calls equals the concurrent call licensing limit, then all the excess initiated calls will be moved to this unmonitored state
8100 Media Transmission Stopped If the call is established successfully and initially there is some RTP/RTCP packet transfer and then the RTP/RTCP packets reception or the signaling termination packets reception stopped for a certain time interval, then the call will be marked as 'Media Transmission Stopped' and moved to the 'Completed Calls' category.
