As far as I can tell on my Aastra phones it takes 2 links to complete 
a transfer. Pressing transfer puts the first call on hold and allows 
you to make a second call. Pressing transfer a second time then 
connects those to calls together and removes you from the call. If 
you only have 1 call allowed you'll need to implement that using 
features.conf or implement the busy stuff in the dial plan.
