Making Phonecall using ionic in phonegap

Continuing the discussion from Making Phone Call from App - href="tel:123":

Hey guys, i am working on the same issue.
I have been using phonegap for testing my ionic project,
When i test it in the chrome browser, button click directs to phone dialer.
But when i test it in phonegap it doesn’t redirect to the dialer.
I have included:
access origin=tel and mail also to it

in my config.xml file but still i couldn’t get the desired output.

Has anything to be added?
Some one help! I am held up in this issue for almost a week ;(
