asterisk users - Sep 2004 - Cisco 79xx + asterisk + some functions Q

Hi,

I am new to Asterisk and have some general questions _before_
I start buying equipent to install and get everything up-and-running.
(this means I have no running Asterisk (yet)).

I have read already a lot of doc, but some things are not
clear to me, since I'am inexperienced in Asterisk and PBX.

The goal:
Make PBX using Asterisk and Cisco 79xx equipment for 25
phones (1 x 7970, 4 x 7960, 20 x 7905 / 7912) + 4 ISDN
BA connections using ELSA ISDN (Hisax compliant) boards.
I will use SIP between Cisco CP 79xx and Asterisk, and
mainly the ISDN gateway towards the public network.

Q's:

1) Status info: can I see on my 7960 equipment (eventualy
   with the 7914 extension) who is free/busy and alike ?

2) Can I use 1 button press on that 7960 to transfer the
   call to that free line ?

3) Besides the physical differences, are there functional
   differences between 7960, 7940, 7912, 7905 ?
   (ea, are there functions (like hold, transfer, ...
   that are missing on a certain model ?) or are the
   firmware images of alle equipments the same ?

4) Can Asterisk (or own extensions/scripts) drive the dis-
   play on the 7960, 7940, 7912, 7905 ?
   (for example: incomming call from XXX => we do db lookup
   => when found, we show their Maintenance status on
   the Cisco display of the phone that answers the call)

5) I understood that the 7920 (Wireless) does not support SIP.
   Does this limit this equipment very much ? (no call transfers,
   or on-screen info, or ... ???)
   Or has anyone heard of a newer model that will support SIP ?

6) Can we make following scenario work with Asterisk ?
   Incomming call => secretary 
   she answers and looks on her 7960 + 7914 who's free
   she transfers to X
   during transfer, a db lookup is made (or own Postgresql)
   to find a matching original tel number. As a parameter,
   X is passed, so via IPC we can do a pop-up on his PC
   (when on) with info of the caller.
   X receives the call on his 7912 / 7905. On his Cisco display
   some extra info is showed to tell him that info was found
   and he should look to his PC.

6) Any direct pointers towards similar projects

Thank you very much,
a-like-to-become Asterisk user/developer.
Alex

No.  The 7914 doesn't work with SIP, either.

Not to the best of my knowledge.

There are two families, 7960/7940 and 7905/7912.  I've heard that the 
7912 UI is slightly better, but I haven't seen it.  I'm happy with my 
7940.

You have room for around 20 characters of caller ID status.  That's 
about the only thing you can display on the Cisco.

The 7920, 7970, and 7935 are SCCP-only.  They'll probably work with one 
of the SCCP drivers for Asterisk, but I haven't tried.

Mostly.  I'm not sure if the 7914 works right with Asterisk and SCCP, 
but the SIP firmware on the Cisco phones won't even recognize it.  
There are a few alternatives--look at the flash operator UI (search the 
wiki for a URL).  The transfer/DB lookup/IPC bit is just a simple 
matter of programming.  The phone pop-up is limited to one line of 
caller ID information.

While it looks like recent SIP images support this "multiple call
appearance" feature, to my knowledge asterisk does not.

I wrote the flash operator panel, a switchboard type console that does
all these things. You can see who is busy or idle or not registered,
you can transfer via drag and drop, you can popup a webpage with the
callerid passed to your web application (in our office, we open a
webpage with customer information and details before we pick up the
phone). You can modify the callerid text before transferring to pass
information, and many features more.. Its not exactly what you want,
but similar. It needs a PC, you cannot do it just with phones.
