Cross Platform Event Notification

Question

I hope you guys can spare a moment with some ideas on how to develop my idea.

I have an Asterisk-based telephone switch . When an incoming call is arriving, I can make sure the server runs an external script of any language. Here comes my development work. I would like to notify a group of listening clients about the call, and probably open a browser page on their computer.

What kind of approach would you take for this sort of server-based push notification? (with no iPhone involved)

I am open to any language. Thanks

Answer 1

You can use or build off a tool like callPopPy , which interacts with Asterisk's existing notification subsystem. More options are listed here .

Answer 2

Maybe have a look at www.pubnub.com .. its commercial, but lets you send 5 million messages a month for free. Essentially it lets you create a named channel, and have X number of clients connect to it and send messages back and forth.

Using one of these services would of course require you to write a client to distribute to your users (in your language of choice) and tie's you in somewhat (shouldn't really be a problem as you could swap in some other solution later if they go under or whatever.) The upside would be, very good x-platform support and a very clean API, infrastructure taken care of for you (for example clients can still connect the the channel even if your asterisk box is down or whatever)

(and no, I don't work for pubnub! but it seems like a no-brainer to use it with the 5mil messages free deal!)
