[Asterisk-Users] Sip & Intercom

[Mike Reiling]

Hello all,
	I noticed that Cisco claims that you can do station to station 
intercom with the 7940/7960 phones, and the Cisco Call Manager.  Does 
anyone have an example SIP header that shows this in action?  Or is it 
something else that triggers the intercom?  I would like to add this in 
to *.

Thanks,
Mike
