 30  * @class
 31  * Create a new phone number instance that parses the phone number parameter for its
 32  * constituent parts, and store them as separate fields in the returned object.
 33  *
 34  * The options object may include any of these properties:
 35  *
 36  * <ul>
 37  * <li><i>locale</i> The locale with which to parse the number. This gives a clue as to which
 38  * numbering plan to use.
 39  * <li><i>mcc</i> The mobile carrier code (MCC) associated with the carrier that the phone is
 40  * currently connected to, if known. This also can give a clue as to which numbering plan to
 41  * use
 42  * <li>onLoad - a callback function to call when this instance is fully
 43  * loaded. When the onLoad option is given, this class will attempt to
 44  * load any missing locale data using the ilib loader callback.
 45  * When the constructor is done (even if the data is already preassembled), the
 46  * onLoad function is called with the current instance as a parameter, so this
 47  * callback can be used with preassembled or dynamic loading or a mix of the two.
 48  * <li>sync - tell whether to load any missing locale data synchronously or
 49  * asynchronously. If this option is given as "false", then the "onLoad"
 50  * callback must be given, as the instance returned from this constructor will
 51  * not be usable for a while.
 52  * <li><i>loadParams</i> - an object containing parameters to pass to the
 53  * loader callback function when locale data is missing. The parameters are not
 54  * interpretted or modified in any way. They are simply passed along. The object
 55  * may contain any property/value pairs as long as the calling code is in
 56  * agreement with the loader callback function as to what those parameters mean.
 57  * </ul>
 58  *
 59  * This function is locale-sensitive, and will assume any number passed to it is
 60  * appropriate for the given locale. If the MCC is given, this method will assume
 61  * that numbers without an explicit country code have been dialled within the country
 62  * given by the MCC. This affects how things like area codes are parsed. If the MCC
 63  * is not given, this method will use the given locale to determine the country
 64  * code. If the locale is not explicitly given either, then this function uses the
 65  * region of current locale as the default.<p>
 66  *
 67  * The input number may contain any formatting characters for the given locale. Each
 68  * field that is returned in the json object is a simple string of digits with
 69  * all formatting and whitespace characters removed.<p>
 70  *
 71  * The number is decomposed into its parts, regardless if the number
 72  * contains formatting characters. If a particular part cannot be extracted from given
 73  * number, the field will not be returned as a field in the object. If no fields can be
 74  * extracted from the number at all, then all digits found in the string will be
 75  * returned in the subscriberNumber field. If the number parameter contains no
 76  * digits, an empty object is returned.<p>
 77  *
 78  * This instance can contain any of the following fields after parsing is done:
 79  *
 80  * <ul>
 81  * <li>vsc - if this number starts with a VSC (Vertical Service Code, or "star code"), this field will contain the star and the code together
 82  * <li>iddPrefix - the prefix for international direct dialing. This can either be in the form of a plus character or the IDD access code for the given locale
 83  * <li>countryCode - if this number is an international direct dial number, this is the country code
 84  * <li>cic - for "dial-around" services (access to other carriers), this is the prefix used as the carrier identification code
 85  * <li>emergency - an emergency services number
 86  * <li>mobilePrefix - prefix that introduces a mobile phone number
 87  * <li>trunkAccess - trunk access code (long-distance access)
 88  * <li>serviceCode - like a geographic area code, but it is a required prefix for various services
 89  * <li>areaCode - geographic area codes
 90  * <li>subscriberNumber - the unique number of the person or company that pays for this phone line
 91  * <li>extension - in some countries, extensions are dialed directly without going through an operator or a voice prompt system. If the number includes an extension, it is given in this field.
 92  * <li>invalid - this property is added and set to true if the parser found that the number is invalid in the numbering plan for the country. This method will make its best effort at parsing, but any digits after the error will go into the subscriberNumber field
 93  * </ul>
 94  *
 95  * The following rules determine how the number is parsed:
 96  *
 97  * <ol>
 98  * <li>If the number starts with a character that is alphabetic instead of numeric, do
 99  * not parse the number at all. There is a good chance that it is not really a phone number.
100  * In this case, an empty instance will be returned.
101  * <li>If the phone number uses the plus notation or explicitly uses the international direct
102  * dialing prefix for the given locale, then the country code is identified in
103  * the number. The rules of given locale are used to parse the IDD prefix, and then the rules
104  * of the country in the prefix are used to parse the rest of the number.
105  * <li>If a country code is provided as an argument to the function call, use that country's
106  * parsing rules for the number. This is intended for programs like a Contacts application that
107  * know what the country is of the person that owns the phone number and can pass that on as
108  * a hint.
109  * <li>If the appropriate locale cannot be easily determined, default to using the rules
110  * for the current user's region.
111  * </ol>
112  *
113  * Example: parsing the number "+49 02101345345-78" will give the following properties in the
114  * resulting phone number instance:
115  *
116  * <pre>
117  *      {
118  *        iddPrefix: "+",
119  *        countryCode: "49",
120  *        areaCode: "02101",
121  *        subscriberNumber: "345345",
122  *        extension: "78"
123  *      }
124  * </pre>
125  *
126  * Note that in this example, because international direct dialing is explicitly used
127  * in the number, the part of this number after the IDD prefix and country code will be
128  * parsed exactly the same way in all locales with German rules (country code 49).
129  *
130  * Regions currently supported are:
131  *
132  * <ul>
133  * <li>NANP (North American Numbering Plan) countries - USA, Canada, Bermuda, various Caribbean nations
134  * <li>UK
135  * <li>Republic of Ireland
136  * <li>Germany
137  * <li>France

962      * This routine will compare the two phone numbers in an locale-sensitive
963      * manner to see if they possibly reference the same phone number.<p>
964      *
965      * In many places,
966      * there are multiple ways to reach the same phone number. In North America for
967      * example, you might have a number with the trunk access code of "1" and another
968      * without, and they reference the exact same phone number. This is considered a
969      * strong match. For a different pair of numbers, one may be a local number and
970      * the other a full phone number with area code, which may reference the same
971      * phone number if the local number happens to be located in that area code.
972      * However, you cannot say for sure if it is in that area code, so it will
973      * be considered a somewhat weaker match.<p>
974      *
975      * Similarly, in other countries, there are sometimes different ways of
976      * reaching the same destination, and the way that numbers
977      * match depends on the locale.<p>
978      *
979      * The various phone number fields are handled differently for matches. There
980      * are various fields that do not need to match at all. For example, you may
981      * type equally enter "00" or "+" into your phone to start international direct
982      * dialling, so the iddPrefix field does not need to match at all.<p>
983      *
984      * Typically, fields that require matches need to match exactly if both sides have a value
985      * for that field. If both sides specify a value and those values differ, that is
986      * a strong non-match. If one side does not have a value and the other does, that
987      * causes a partial match, because the number with the missing field may possibly
988      * have an implied value that matches the other number. For example, the numbers
989      * "650-555-1234" and "555-1234" have a partial match as the local number "555-1234"
990      * might possibly have the same 650 area code as the first number, and might possibly
991      * not. If both side do not specify a value for a particular field, that field is
992      * considered matching.<p>
993      *
994      * The values of following fields are ignored when performing matches:
995      *
996      * <ul>
997      * <li>vsc
998      * <li>iddPrefix
999      * <li>cic
1000      * <li>trunkAccess
1001      * </ul>
1002      *
1003      * The values of the following fields matter if they do not match:
1004      *
1005      * <ul>
1006      * <li>countryCode - A difference causes a moderately strong problem except for
1007      * certain countries where there is a way to access the same subscriber via IDD
1008      * and via intranetwork dialling
1009      * <li>mobilePrefix - A difference causes a possible non-match
1010      * <li>serviceCode - A difference causes a possible non-match
1011      * <li>areaCode - A difference causes a possible non-match
1012      * <li>subscriberNumber - A difference causes a very strong non-match
1013      * <li>extension - A difference causes a minor non-match
1014      * </ul>

1017      * @return {number} non-negative integer describing the percentage quality of the
1018      * match. 100 means a very strong match (100%), and lower numbers are less and

1399      * This function normalizes the current phone number to a canonical format and returns a
1400      * string with that phone number. If parts are missing, this function attempts to fill in
1401      * those parts.<p>
1402      *
1403      * The options object contains a set of properties that can possibly help normalize
1404      * this number by providing "extra" information to the algorithm. The options
1405      * parameter may be null or an empty object if no hints can be determined before
1406      * this call is made. If any particular hint is not
1407      * available, it does not need to be present in the options object.<p>
1408      *
1409      * The following is a list of hints that the algorithm will look for in the options
1410      * object:
1411      *
1412      * <ul>
1413      * <li><i>mcc</i> the mobile carrier code of the current network upon which this
1414      * phone is operating. This is translated into an IDD country code. This is
1415      * useful if the number being normalized comes from CNAP (callerid) and the
1416      * MCC is known.
1417      * <li><i>defaultAreaCode</i> the area code of the phone number of the current
1418      * device, if available. Local numbers in a person's contact list are most
1419      * probably in this same area code.
1420      * <li><i>country</i> the 2 letter ISO 3166 code of the country if it is
1421      * known from some other means such as parsing the physical address of the
1422      * person associated with the phone number, or the from the domain name
1423      * of the person's email address
1424      * <li><i>networkType</i> specifies whether the phone is currently connected to a
1425      * CDMA network or a UMTS network. Valid values are the strings "cdma" and "umts".
1426      * If one of those two strings are not specified, or if this property is left off
1427      * completely, this method will assume UMTS.
1428      * </ul>
1429      *
1430      * The following are a list of options that control the behaviour of the normalization:
1431      *
1432      * <ul>
1433      * <li><i>assistedDialing</i> if this is set to true, the number will be normalized
1434      * so that it can dialled directly on the type of network this phone is
1435      * currently connected to. This allows customers to dial numbers or use numbers
1436      * in their contact list that are specific to their "home" region when they are
1437      * roaming and those numbers would not otherwise work with the current roaming
1438      * carrier as they are. The home region is
1439      * specified as the phoneRegion system preference that is settable in the
1440      * regional settings app. With assisted dialling, this method will add or
1441      * remove international direct dialling prefixes and country codes, as well as
1442      * national trunk access codes, as required by the current roaming carrier and the
1443      * home region in order to dial the number properly. If it is not possible to
1444      * construct a full international dialling sequence from the options and hints given,
1445      * this function will not modify the phone number, and will return "undefined".
1446      * If assisted dialling is false or not specified, then this method will attempt
1447      * to add all the information it can to the number so that it is as fully
1448      * specified as possible. This allows two numbers to be compared more easily when
1449      * those two numbers were otherwise only partially specified.
1450      * <li><i>sms</i> set this option to true for the following conditions:
1451      *   <ul>
1452      *   <li>assisted dialing is turned on
1453      *   <li>the phone number represents the destination of an SMS message
1454      *   <li>the phone is UMTS
1455      *   <li>the phone is SIM-locked to its carrier
1456      *   </ul>
1457      * This enables special international direct dialling codes to route the SMS message to
1458      * the correct carrier. If assisted dialling is not turned on, this option has no
1459      * affect.
1460      * <li><i>manualDialing</i> set this option to true if the user is entering this number on
1461      * the keypad directly, and false when the number comes from a stored location like a
1462      * contact entry or a call log entry. When true, this option causes the normalizer to
1463      * not perform any normalization on numbers that look like local numbers in the home
1464      * country. If false, all numbers go through normalization. This option only has an effect
1465      * when the assistedDialing option is true as well, otherwise it is ignored.
1466      * </ul>
1467      *
1468      * If both a set of options and a locale are given, and they offer conflicting
1469      * information, the options will take precedence. The idea is that the locale
1470      * tells you the region setting that the user has chosen (probably in
1471      * firstuse), whereas the the hints are more current information such as
1472      * where the phone is currently operating (the MCC).<p>
1473      *
1474      * This function performs the following types of normalizations with assisted
1475      * dialling turned on:
1476      *
1477      * <ol>
1478      * <li>If the current location of the phone matches the home country, this is a
1479      * domestic call.
1480      *   <ul>
1481      *   <li>Remove any iddPrefix and countryCode fields, as they are not needed
1482      *   <li>Add in a trunkAccess field that may be necessary to call a domestic numbers
1483      *     in the home country
1484      *   </ul>
1485      * <li> If the current location of the phone does not match the home country,
1486      * attempt to form a whole international number.
1487      *   <ul>
1488      *   <li>Add in the area code if it is missing from the phone number and the area code
1489      *     of the current phone is available in the hints
1490      *   <li>Add the country dialling code for the home country if it is missing from the
1491      *     phone number
1492      *   <li>Add or replace the iddPrefix with the correct one for the current country. The
1493      *     phone number will have been parsed with the settings for the home country, so
1494      *     the iddPrefix may be incorrect for the
1495      *     current country. The iddPrefix for the current country can be "+" if the phone
1496      *     is connected to a UMTS network, and either a "+" or a country-dependent
1497      *     sequences of digits for CDMA networks.
1498      *   </ul>
1499      * </ol>
1500      *
1501      * This function performs the following types of normalization with assisted
1502      * dialling turned off:
1503      *
1504      * <ul>
1505      * <li>Normalize the international direct dialing prefix to be a plus or the
1506      * international direct dialling access code for the current country, depending
1507      * on the network type.
1508      * <li>If a number is a local number (ie. it is missing its area code),
1509      * use a default area code from the hints if available. CDMA phones always know their area
1510      * code, and GSM/UMTS phones know their area code in many instances, but not always
1511      * (ie. not on Vodaphone or Telcel phones). If the default area code is not available,
1512      * do not add it.
1513      * <li>In assisted dialling mode, if a number is missing its country code,
1514      * use the current MCC number if
1515      * it is available to figure out the current country code, and prepend that
1516      * to the number. If it is not available, leave it off. Also, use that
1517      * country's settings to parse the number instead of the current format
1518      * locale.
1519      * <li>For North American numbers with an area code but no trunk access
1520      * code, add in the trunk access code.
1521      * <li>For other countries, if the country code is added in step 3, remove the
1522      * trunk access code when required by that country's conventions for
1523      * international calls. If the country requires a trunk access code for
1524      * international calls and it doesn't exist, add one.
1525      * </ul>
1526      *
1527      * This method modifies the current object, and also returns a string
1528      * containing the normalized phone number that can be compared directly against
1529      * other normalized numbers. The canonical format for phone numbers that is
