====== nam ======
call.nam is a string property containing global path to the call object.

When calling call object functions from for example a setTimeout call you need to provide a unique name of the call object to be called as a string. call.nam contains such a unique name string.

===== Value =====
"wrtc.x.call[//index//]"

===== Example =====
When answering a call it is important to call answerCall() of the correct call object. Usually an "Answer" button is displayed by [[ixnx:wrtc:js:api:wrtc:onincomingcall|wrtc.onIncomingCall()]] function and when user klicks on the button answerCall() is called. To be able to call answerCall() of the correct call object you need to use the call.nam property:
<code>
wrtc.onIncomingCall = function(call) {
    ...
    status.innerHTML = "<input type=\"button\" value=\"Answer\" onclick=\"" + call.nam + ".answerCall()\" />";
    ...
}
</code>
You cannot use call.answerCall() as call is not a global variable.
