Does anyone know the maximum number of digits for an international phone number? Doing some searching, it looks like 16 numbers including the "011" is the maximum number, because 17 is just not found: OK: 1234567890123456 http://www.google.com/search?q=011XXXXXXXXXXXXX Not OK: 12345678901234567 http://www.google.com/search?q=011XXXXXXXXXXXXXX This fellow includes "011xxxxxxxxxxxxx.T" in his dial plan. Will this provide for more than 16 numbers?http://www.vovida.org/pipermail/mgcp/2003-November/001848.html Does anyone have some definitive sources for this subject?

Especially when more countries use '00' for their outbound international prefix than use '011'. As has already been mentioned recently, at least one country (Germany) has no hard limit on the length of a number - extra digits after the base number are delivered to the CPE for internal routing - kind-of self-administered DDI ranges.

[asterisk-users] International dialplans for Asterisk?
I think the + convention started off because different countries have different international access codes. Well, on GSM networks, + can be a part of the number to represent the international access code ( the traditional access code in India is 00 for international). So to call Digium, from my GSM phone, I can use 0018775468963 or +18775468963 and Allison will answer :) Rajeev On 12/22/06, Doug Crompton <doug@crompton.com> wrote:> > Question...

In the US and Canada it will be 011, in most parts of the world "00", and there is Russia with its exotic "08 wait for beep 10"... The "+" should work in GSM mobile networks and most SIP providers seem to accept it. For callerid, there seem to be several cases. One of my providers (the others manage better and always give "00492281234567" formatted numbers) gives CID as "+491601234567" for calls from one German mobile network, "491637654321" from a second network and "02281234567" from landline, so my dialplan has to cope with that such that my endpoints show the proper number. This is done by the following logic: If number begins with "+", strip it. If number begins with anything but 0, prepend "00". If number begins with "0049", replace by "0". Although in Germany you can dial "0049" (region) (number), readability is better when there is only the "0" (region) (number) on the display - especially as numbers tend to get long, and e.g. Grandstream BT-100 only have a 12-digit display. BTW the longest number I _think_ is planned in Germany is 9 digits after the area code for 2- and 3-digit area codes, 8 for 4-, and 7 for 5-digit areacodes. There is one exception though that I know of: One of our ministeries has usually 55-4444 numbers (55 being their number, then four digits DDI), but their fax numbers are 8-digit. Thus resulting in total in 011-49-228-55-87654321 from US, 18 digits. If you can, leave room for long numbers. BR Anselm
