[SIPForum-discussion] E.164

[Stoller, Jeff]

+1 is domestic E.164 format. + and then the number is for international.  To convert a US phone number like 415 555 2671 to E.164 format, you need to add the '+' prefix and the country code (which is 1) in front of the number so it will look like +14155552671.

Subject: [SIPForum-discussion] E.164

Looking for some clarification.  I have a vendor that claims +1 indicates an internationally originated call.  I disagree and feel that it is merely an indication that it is in E.164 format.  Anyone want to chime in?
