Can you explain what you mean by a "SIP trunk"?

SIP just has addresses - sometimes slightly hidden away in sip.conf behind 
a SIP peer.  So if you Dial(SIP/remotehost/number), a SIP invite is sent 
to the host IP address defined in the SIP peer in sip.conf.  If you 
Dial(SIP/number at hostname) then the invite is sent to the host "hostname".  
Normally it makes no difference to either side how many other calls may 
already by in progress between the two sides.
