[cisco-voip] E.164 dialing

[Ryan O'Connell]

Hi Lelio,

We were thinking of going with 11 digits because the dial-plan extends beyond the NANP into Europe. I believe a fully qualified E.164 number requires the country code. So by adding a 1 in front of the NA numbers we well not see conflict with the European numbers.

exchange 555 is used for stuff like this

555-0100 to 555-0199 is reserved for fictional use, you should be fine with
these. Just add different area codes if you need more.

I'm wondering why you would want 11 digit DNs though, I'm pretty sure E164
deployments for DNs only use 10.
