This object reflects the total number of Queued
(182) responses received by the user agent since system startup.
Inbound Queued responses indicate that the users
this system is attempting to call are temporarily
unavailable but the SIP agents operating on behalf
of those users wish to queue the calls rather than
reject them. When the called parties become available,
this system can expect to receive the appropriate
final status response. The Reason-Phrase from the
Queued response messages Status-Line may give further
details about the status of the call. Multiple
Queued responses to update this system about the status
of the queued call my be received.
