M.1.1 Successful Pipelined Start-up

The following is an example depiction of pipelined start-up. The client probes the server features during the optional DECRIBE interaction. Note that the first set-up message does not contain a "Require" header.

M.1.2 Unsuccessful Pipelined Start-up

In this example the client uses the pipelined start-up feature towards a server which does not support this feature. In principle the client may keep knowledge about feature capabilities.

Note the first setup interaction is successful, since the client has not used the require header.
