asterisk users - Jul 2005 - Any Ideas??? 3rd time posting => Sipura SIP Phones Multi-Line Appearance... How to use? |----->WAS----> NEWBIE Question: Asterisk with multiline/button phones

Still looking for some direction with this subject:

I think the term is called multi-line appearance....
Is this something that is directly supported in Asterisk?
I can't seem to find any information on it or how to actually use it....

This is where you have several sipura-841 SIP phones for example... if
someone pickes up 'line1' I'd like the light to come on on ALL
phones to indicate someone is using 'line 1' and they should NOT be able
to pick up 'line 1' so long as that 'line1' is in use by another
phone.

I'd like this to work in a SIP only environment.
We don't have actual CO lines but have several SIP accounts being used
like CO lines...

Is there a way to make these phones do this??
This is a common feature on just about any conventional phone system 'line
seize' as it may be called to some...

How the heck do you do it with sip? and does Asterisk do this
readily?

Thanks!

Steve

picks up a 'line' or is using a 'line' or puts a 'line'

and then would like to pick it up from another phone just by pushing the
'line #3' or 'line #4' button that is on hold and
lit/flashing.

You are trying to emulate a key system, Asterisk is a PBX. I don't you 
will get this done as there is no concept of lines, all phones are 
extensions.

Generally speaking one works against one's own best interests when he 
reminds the group that he has been posting on a topic repeatedly without 
anyone answering.

What you are asking for is not reasonable; it's not the way Asterisk 
works, and there is in my mind (and I'll bet in the minds of others) no 
logical reason to "need" what you're asking for.  Perhaps the
response
is "so that I can construct an Asterisk system that has 100% of the 
exact behavior of a key system."

But if that's what you want, and that's all that you want, and you must 
have exactly that, get a key system.  Asterisk is the wrong tool for the 
job.

The idea would be to get a network dump of the phones working in this 
way and then see what packets are needed.  You can then try and rig 
something up with asterisk or even an external program to send these 
packets.  Is there anything on the web about how these lights are caused 
to turn on or off?

This function is based on a non-standardized extension to SIP made
by Broadsoft. I have all the specs and are looking into this. Don't
expect anything to happen quickly though, I have to complete another
large SIP project first (SIP Transfers) and then start looking into
this. It requires quite a lot of code, but I still think it's possible.
Guess, we'll see.
