asterisk users - Apr 2003 - SIP and special functions - do they work?

Do functions like call forwarding, do not disturb and so on work with SIP 
phones?  I had these features working with the S100 USB device but can't 
seem to get them to work with the phones that are plugged into the ATA186s. 


Also, how do I get an extension that's plugged into an ATA186 to present 
caller ID?

Thanks...

They're somewhat dependent upon the phone itself.  In *general* Asterisk
does support Transfer via REFER but not via BYE;also= at this time.

Hrm, dunno.  Does "sip debug" suggest we are sending it?
