Basically, this is TAPI, please see:
http://en.wikipedia.org/wiki/Telephony_Application_Programming_Interface[^].

SMS is presently a part of GSM set of standards, please see:
http://en.wikipedia.org/wiki/SMS[^],
http://en.wikipedia.org/wiki/Global_System_for_Mobile_Communications[^].

At the same time, interconnections with other network is supported. For further detail, please see the articles referenced above.

If I understand your question correctly:

You can place a telephone call on most smart phones by using a link of the format:

HTML

<a href="tel:+1-123-555-1212"></a>

Here's the full description of the tel protocol: http://tools.ietf.org/html/rfc3966[^]

Generally speaking the number should be specified as a "global number" starting with the + and then the country code, etc. so that it's valid from anywere in the world. The dashes are supposed to be ignored, but not all mobile devices may implement the protocl correctly.

Send a SMS with a link such as:

HTML

<a href="sms:123-555-1212?body=hello%20there'"></a>

Full description here: http://tools.ietf.org/html/rfc5724[^]

Again, not all mobile devices may support it, or implement it correctly.

Lot's more semi-useful URI schemes are described here: http://en.wikipedia.org/wiki/URI_scheme[^] with plenty of links to the full descriptions.
