[cisco-voip] E.164 dialing

[Ryan West]

Ryan,

Taken from NANP site:
http://www.nationalnanpa.com/about_us/abt_nanp.html

NANP numbers are ten-digit numbers consisting of a three-digit Numbering Plan Area (NPA) code, commonly called an area code, followed by a seven-digit local number. The format is usually represented as
NXX-NXX-XXXX
where N is any digit from 2 through 9 and X is any digit from 0 through 9.
So, it seems the poster from earlier who mentioned 11X / 10X numbers would have a valid option.

You could also get away with using these, as they aren't even close to being on the map:

37X and 96X Two blocks of 10 codes each have been set aside by the INC for unanticipated purposes where it may be important to have a full range of 10 contiguous codes available.

Yes agreed and understood, in fact the plan is based on UC version 7. So back to my questions though, with E.164 NANP and E.164 with UK does anyone know if there are private numbers reserved? As far as I can see any Area code that repeats itself has not been assigned to any NANP number as of yet except for 888. They have been set aside as ERC (Easily Recognizable Codes) numbers. This being said it doesn't clearly define if these numbers will ever be introduced as NANP numbers. So based on this using 444 XXX XXXX in NANP we should be safe. As for the UK it seems as though they set aside a block for "Corporate Numbering" 05x xxxx xxxx.

Thoughts?

Ryan

I agree with Matt.  so many changes in UC7, I would hold off making any significant dialplan changes until that release.

That's what I'm saying is that I shouldn't need the "+" if the number is a fully qualified E.164 number.

Thoughts?

Unfortunately, you are going to have to wait for UCM 7.0 to have full
E164 support.  Currently UCM throws up when it gets a '+'.

Hello,

I am working on a Dialplan that is based on E.164 numbers. Essentially
all internal DN's will be the fully qualified E.164 number without the
"+" so for NANP that will be 11 digits and in Europe it will consist of
country-code followed by local exchange. Using partitions and CSS's to
maintain interal 4 digit dialing intra-site and full E.164 inter-site.
For DID's the above plan is pretty straight forward but for non-DID's I
can't seem to find any ranges within the NANP that are designated as
private addresses. So if I want to assign 100 DN's to be voicemail ports
or lobby phones or whatever I was wondering what I should make these
numbers so that it doesn't overlap with any PSTN numbers.

If anyone can share thoughts or their experiences in this area that
would be helpful thanks


Ryno
