I modified the code to output phone in this format Value: +38 (095) 411-22-23 Here you can check it enter link description here

    var myApp = angular.module('myApp', []);

myApp.controller('MyCtrl', function($scope) {
  $scope.currencyVal;
});

myApp.directive('phoneInput', function($filter, $browser) {
    return {
        require: 'ngModel',
        link: function($scope, $element, $attrs, ngModelCtrl) {
            var listener = function() {
                var value = $element.val().replace(/[^0-9]/g, '');
                $element.val($filter('tel')(value, false));
            };

            // This runs when we update the text field
            ngModelCtrl.$parsers.push(function(viewValue) {
                return viewValue.replace(/[^0-9]/g, '').slice(0,12);
            });

            // This runs when the model gets updated on the scope directly and keeps our view in sync
            ngModelCtrl.$render = function() {
                $element.val($filter('tel')(ngModelCtrl.$viewValue, false));
            };

            $element.bind('change', listener);
            $element.bind('keydown', function(event) {
                var key = event.keyCode;
                // If the keys include the CTRL, SHIFT, ALT, or META keys, or the arrow keys, do nothing.
                // This lets us support copy and paste too
                if (key == 91 || (15 < key && key < 19) || (37 <= key && key <= 40)){
                    return;
                }
                $browser.defer(listener); // Have to do this or changes don't get picked up properly
            });

            $element.bind('paste cut', function() {
                $browser.defer(listener);
            });
        }

    };
});
myApp.filter('tel', function () {
    return function (tel) {
        console.log(tel);
        if (!tel) { return ''; }

        var value = tel.toString().trim().replace(/^\+/, '');

        if (value.match(/[^0-9]/)) {
            return tel;
        }

        var country, city, num1, num2, num3;

        switch (value.length) {
            case 1:
            case 2:
            case 3:
                city = value;
                break;

            default:
                country = value.slice(0, 2);
                city = value.slice(2, 5);
                num1 = value.slice(5,8);
                num2 = value.slice(8,10);
                num3 = value.slice(10,12);            
        }

        if(country && city && num1 && num2 && num3){
            return ("+" + country+" (" + city + ") " + num1 +"-" + num2 + "-" + num3).trim();
        }
        else if(country && city && num1 && num2) {
            return ("+" + country+" (" + city + ") " + num1 +"-" + num2).trim();
        }else if(country && city && num1) {
            return ("+" + country+" (" + city + ") " + num1).trim();
        }else if(country && city) {
            return ("+" + country+" (" + city ).trim();
        }else if(country ) {
            return ("+" + country).trim();
        }

    };
});
