[cisco-voip] E.164 dialing

[Ryan O'Connell]

Hi Walt,

Agreed on the 110 and 111 codes not conflicting with anything but when you read through NANP documents it doesn't specifically state that these will always remain this way. Like the 10.0.0.0 and 192.168.0.0 will always be private class. I'm sure we'll be ok using these ranges but it would be nice to know if it will remain this way.

Thoughts?

110xxxx and 111xxxx don't conflict with anything.

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.
