[cisco-voip] Intercom in Callmanager

[Schuett, Court (MBNAP it)]

That's what we did.  We ran from an ATA 186 port into the amplifier that ran
into the speakers.  We had a wiring company set up the amp and speakers for
us.  It was pretty simple and it sounded like they had done it before.
Connecting it to the ATA was also very simple.  Just assigned the ATA a
number and when people want to announce over the speakers, they just call
that number.  There was a catch to it though.  When the number was called,
the speakers would pick up, but they wouldn't let go.  What happened was the
person would call, make the announcement and then hang up.  But the speakers
would still be broadcasting and would eventually go to a busy signal.  To
fix this, you have to go in and change the polarity on the ATA to 0x00008 I
believe.  Might want to call TAC and confirm that though.

You can consider a BOGEN TAMB or a VALCOM unit to take the analog signal and
provide the call supervision required. They have audio outputs that you can
feed directly into an amplifier which feeds the speakers. We do that on
campus (but use a VG248 port).

Court,
 
Can you explain the ATA Warehouse paging solution a little more?  I have an
agency in my County that would be interested in something similar.  In
particular what kind of interface does the speaker system need for this to
function?

What kind of intercom are you looking for?  I've set up second lines on a
phone that are set to auto-answer that can then be used as a
pseudo-intercom.  Or you can set up special partitions with only specific
lines in it.  We've also set up loud speakers in a warehouse attached to an
ATA for paging.  Depends on what you're looking for in an intercom though.

I know there are third party products that can do an intercom.  Is there any
'poor mans' version of this that any of you have tried.  I was thinking
about taking a PLAR shared line appearance approach, anyone tried it?
Suggestions?

 

This is for a Callmanager 3.3 install

 

Thanks again!
