Thank you for your reply as it is exactly what we would need. Sorry I didn't find it myself. I do have a question about configuration within Asterisk.
I'm reading the PDF on the Cisco Expansion module and it says 'When used as a DN key buttons are illuminated ...' Is that what we are doing within Asterisk or Trixbox when we configure an extension?

What hardware (Phone or other) could we give the receptionist to do this? You're probably looking for something like this: http://www.cisco.com/en/US/products/hw/phones/ps379/products_data_sheet0 9186a008008883d.html I have no experience integrating this specific piece of hardware with Asterisk, but I've done what you're trying to do with the Grandstream equivalent for our front reception: http://www.grandstream.com/gxp2000.html and http://www.grandstream.com/gxp2000ext.html As I understand it, so long as the device can do a SIP SUBSCRIBE for each extension you want to monitor and you configure hints in your Asterisk dialplan for those extensions, it should work. You may need to set 'subscribecontext' (in sip.conf) for the phone that will be watching the extensions unless your hints are in the same context as the phone uses for outbound dialing. Of course, what the device does with the various payloads contained in the SIP NOTIFY messages is going to be different for each phone. On the Grandstream I can see 'not in use' (solid green) and 'ringing' (flashing red) distinctly, but 'unavailable' and 'in use' are both mapped to a solid red, which makes it somewhat useless for transiently connected user agents like softphones. Hopefully someone with experience will speak up and confirm that the 7900 series does interop properly with Asterisk for SUBSCRIBE and NOTIFY. If that doesn't work, you could always go with a software solution, like the Flash Operator Panel. voip-info has a list (look at the "Operator" section on the page): http://www.voip-info.org/wiki/view/Asterisk+GUI -- j. -- This message has been scanned for viruses and dangerous content by Athens Hyperion Scanner, and is believed to be clean.
