[cisco-voip] using Annunciator and/or MOH for high volume announcements

[Ryan Ratliff]

I'm sure there are a number of apps out there that can send requests  
to phones to hit a web page (to display something on the LCD) and  
then tell the phone to go offhook and listen to a multicast RTP  
stream.    This is probably the mechanism products like Informacast  
from Berbee and others do their broadcast paging, or at the least is  
one way to do something like this.

As for the scalability parts any time a call is on hold in CM you  
have to have something that is putting the call on hold.  I'm not  
sure if it's possible for a CTI RP to put a device on hold without  
using a CTI port but if the CTI port is required you then have a  
limit to the number of phones that can listen to the message based on  
the number of CTI ports your app can register.

Can you elaborate on this a bit?

We are hoping to use something like IPCelerate/Cistera to send a  
broadcast page out, but wanted a number for people to call for  
updates, etc. People will be very worried if there is no number to call.

You'll run into the same scalability issue with both Annunciator or  
CTI ports as you would Unity ports I'm afraid.    For high volume (in  
the 1k to 10k+ range) I think a broadcast page instrucing the phone  
to listen to a multicast stream is the way to go and even that has  
the limitation of users starting to listen mid-message.

I'm wondering if there is a way to use the annunciator or MOH as a  
high volume announcement source. We are looking at emergency  
communcations on campus and would like a call in number that people  
can call that will give them information. Even if it is something  
that needs technical staff to implement. I know I can use  
callhandlers, but that would easily take up our 96 ports once the  
message went out. I was hoping something like a blocked route pattern  
playing an announciator or calling a CTI route point that immediately  
put someone on hold.

I know people have talked about it in the past, just wondering if  
there has been any updates or new discoveries.
