[cisco-voip] Spam: Re: Using CME to page to every phone

Thu Jul 30 14:53:39 EDT 2009

For audio pages, the Cistera application uses CTI super providers to instruct phones to join a multi-cast stream. Once all phones have joined, it begins the multi-cast stream. It's not bad - we can get about 4000 phones subscribed in under 1 minute.

All applications I have seen use HTTP post to the phones. 

There is another method of pushing the XML instructions via a CTI connection through CM. This is typically even more limited as CM cannot process large number of phones concurrently. This would be more restrictive than distributed TCP sessions with distributed authentication URL's.

Wes, 

Do you know how IP Celerate or Syn-Apps access the ip phones for a page?

Initial delivery, yes. After first successful authentication the phone caches the success. 

1st page out to 200 phones - 200 phones hit authenticate.jsp and must be authenticated. 
2nd page out to 2000 phones including the 200 phones that got the first page - only 1800 phones hit authenticate.jsp and await response. 

Several vendors work around this by hosting their own authentication URL. That URL returns success only if it is the username and password for their application. All other http requests are passed through to CM. This is also the workaround for anyone on older versions of CM.

Does this mean if a third party takes advantage of this, they can speed up message delivery on UCM6/7 deployments over CCM4 deployments?

There is also an added bit of scalability fun for the authentication URL for UCM deployments: 

CSCsu87230 XMLPost to phones delayed or failed due to authenticate.jsp 

In versions with this resolved performance finally exceeds the authentication rate we observed in CM4.x.

If you've hit 2000 phones and are likely to get more, you might have to start looking at Cistera. They are the only one that I am aware of that can control more than 2000 phones on one appliance. Granted, I didn't look hard at SYNAPPS or Berbee, but we didn't like them for the fact they are on a Windows based platform. Cistera is on Linux. IPCelerate definately need multiple servers which would make administration a pain for us with almost 8000 endpoints.

if you have 2000 end points CME is out, are you running Call Manager already? If so you will need to look at 3rd party application to integrate with CUCM. We have used SingleWire InformaCast with good success (formerly know as Berbee) I have heard some good things about IPcelerate and Syn-apps as well, but I don't have any experience with them.

I am trying to find out if and how good is CME for ip phone paging? I have about 2000 end points across a fiber network. I need to be able to page to the speaker of each phone at least. We currently have a solution, but are starting to entertain other possible solutions.

Why is CME not working for a paging? How many phones are you trying to send to? I have not had a problem using CME to page.

Hi, 

Has anyone used CME to page to every phone? I need to find a possible other paging solution. Thanks.
