[cisco-voip] E.164 dialing

[Brian Van Benschoten]

What about office code "555" the ones you always see in the movies ?
Is it really true that 555 is never used by the phone companies in North America

( any area code )  555 (any 4 digits)

Subject: [cisco-voip] E.164 dialing



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
