Push Notifications in Windows Phone 7

Hi,

I'm developping a webservice in WCF.
Windows Phone devices will get data from the webservice but i would like to know if push notification will work or i need to subscribe to a windows cloud service (azure)

So my question is : is it possible to send push notification without microsoft cloud services? and if yes, how the device can subscribe?

i read article to send notification to the device :

http://msdn.microsoft.com/en-us/library/ff402545%28v=vs.92%29.aspx

and

http://msdn.microsoft.com/en-us/library/ff941124%28v=vs.92%29.aspx

but to send the notification, they have written this line :

// The URI that the Push Notification Service returns to the Push Client when creating a notification channel.
string subscriptionUri = "<Notification Channel URI>";

how can i get the "notification channel uri"?


Thank you for helping,

Kind Regards.
