[asterisk-users] Learn some terminology before mountingthistask.

Mon Aug 6 12:35:23 CDT 2007

All,(Ryan-Your response saved me lots of R&D time- Thank you very much)

I have been on TixBox site all morning reading through the MANY posts as
recent as 6-4-2007 on SLA and the need or reason it is not needed.

1)      In our office we do not have a single receptionist, rather a
ring group (Consists of 4 customer support people) that answer inbound
calls and directs them to the right person/dept.

2)      As is stands they each have other responsibilities and the
phone(s) are a split responsibility (Yes I am trying to show them a
better way)

Because of this, FOP or HUD would get in the way of the other
applications they are working with on the desktop(Although it is the
PERFECT solution for a dedicated reception person IMHO)

3)      The ONLY necessity here is that they be able to look down at the
hardware at a glance to see if someone is on the phone

4)      I was sticking with Cisco as I am very versed in
deployment/support and didn't want to support many different phones
however,

If the grandstream is what it takes....That's what we will do.

5)      How do the grandstreams get their configuration info? TFTP
similar to the Cisco model?

The 7914 only works under SCCP; the SIP firmware does not support it at
all (the expansion panel won't even power on fully.) The SCCP channel
driver under Asterisk doesn't really support the 7914 very well,
currently it will only show onhook/offhook state (though there has been
much discussion recently about changing this.) If you want to do this
with SIP then you're better off with something like the grandstream
mentioned, or just use the Flash Operator Panel (IMO it gives you more
flexibility at a much lower cost.)

I have personally found "receptionist phone" functionality handled much
better with FOP. I have a 7914 and its functionality (and usefulness) is
very limited under Asterisk.

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?  (A Directory Number??)

You're probably looking for something like this:

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
