[cisco-voip] SIP extensions and JTAPI

[Matthew Saskin]

I would concur.  With an extension hanging off a SIP trunk, callmanager 
just knows about a route pattern to send calls across that trunk - it's 
up to the device serving as your sip proxy to handle extending the call 
to the SIP endpoint, etc., no?
