The PhoneCall control is used on devices that have
telephone ability. On these devices, it will render as a command that
the user can select to dial the specified phone number. You can set
the Text property to configure the text that will
appear, and you must set the PhoneNumber property
to specify the nunber that will be dialed when the control is
selected. This property accepts a string that can use multiple phone
number formats, including brackes, dashes, and periods. A phone
number can start with the + sign and an optional country or region
code. Examples of valid numbers include 800.522.2920, +1 (425)
885-8080, and +91335303197. i-Mode phones impose their own rules on
valid phone numbers, which are described in detail the MSDN
reference.

On a device that does not provide telephony capability, the
PhoneCall control can render as a link to a URL.
You can set this URL using the AlternateUrl
property. In addition, you can configure the text that will be
displayed using the AlternateFormat string. By
default, this property is "{0}
{1}". This means that on non-telephony devices, the
PhoneCall will display the Text
property with the PhoneNumber property
concatenated to it (with a space separating them). You can alter the
AlternateFormat property to insert your own text.
