I configured asterisk zimlet in order to click to call .

It work fine for the the asterisk extensions in the dialplan but i can't dial the external numbers !

When I dial a number with 10 digits 1 is append (us) i've tried to change that in asterisk .js .
if (numStr.length == 10) {numStr = "1"+numStr;} to if (numStr.length == 10) {numStr = ""+numStr;} without success anyway the dialded number can't be reached !!

any idea
