Assembly: System.Web.Mobile (in system.web.mobile.dll)
For devices with telephony capability, such as a cell phone, the PhoneCall control renders a command that the user can select to dial the specified phone number.
On devices without telephony capability, the PhoneCall control renders alternate text, possibly including the phone number or a link; it is not treated as a command that has dialing capability.
The following code example demonstrates how to add several phone numbers to a Panel on your page. One PhoneCall control has an AlternateUrl and the phone number appears as a link on devices that cannot make a phone call.
The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information, see ASP.NET Web Page Code Model.
