Intercom in Callmanager
|
|
| Burton, Jason 2005-10-28, 5:45 pm |
| 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!

| 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.

| If they are in a call on the primary line, does it automatically click
over? Just curious.

to page a department when she gets a call at the main number. They want
to be able to tell the group they have a call parked extension .....
So I guess I was thinking about doing what you suggested, with putting
the PLAR on the receptionist phone to call the 'shared group' autoanswer
line.
Do you run into any problems once you cross a certain threshold of
users?

with number of users. To be honest, I've only done it with single lines,
but I don't think there would be a problem with multiple lines. I guess it
depends on how many you're thinking about putting it on ;)

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?

why most of the 3rd party solutions use multicast for paging.

| 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.

Subject: RE: [cisco-voip] Intercom in Callmanager
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.

Subject: [cisco-voip] Intercom in Callmanager
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!

Classic disconnect supervision problem. When you have an analog line
it is difficult to tell something at the other end that the call is
over. (Humans are easy -- the 'goodbye' protocol signals the end of
the conversation, so they hang up.)
Disconnect supervision on analog lines is typically handled by:
- shorting the line (removing voltage)
- reversing polarity of the line
- playing special tones (rare)
Don't forget that the end device has to support that particular
disconnect supervision as well...
Last I'd heard is that the ATAs have *NO* disconnect supervision, but if
you've gotten them to break with the speakers, obviously *something*
is working. Thanks for the tip.

| We have a VG248 and were told by cisco to use one of the aforementioned adapters for call supervision. Only after did I find out that that VG248 has the following Call Supervision modes: drop loop current, reverse polarity. Would either of them worked in out situation? Who knows. Something to consider, however.
