IMHO, a good fix is: REQ-16 The mechanism should support a way for a UA to seize a particular appearance number and also send the request at the same time. This is needed when an automatic ringdown feature (a telephone configured to immediately dial a phone number when it goes off hook) is combined with shared appearances - in this case, seizing the line is >>>integrated with<<< dialing.
