Add final part of previously committed work for answered elsewhere in queue - the missing piece that started with app_dial() earlier on.

This is to avoid having the list and counter of missed calls being touched by queue calls. Add the C option to queue() and nothing 
will be logged on phones that support the Reason: header on SIP cancel, like the SNOM phones.
