E164 Numbering scheme explanation. #

Your provider only accepts calls with a correct address presentation in an E164 format. To address calls, the SIP protocol contains a Uniform Resource Identifier (URI) schema. A SIP address or URI is written in a similar fashion to an e-mail address:

The number part of the URI is formatted according an E164-formatted number scheme, issued by the iNUM initiative. That E164 number scheme is a concatenation of: International prefix symbol (according E123), country code, area code, company prefix and extension number.


For example:    sip:

In the above example: “+” (E123), “1” (country code, without leading zero`s), “999” (area code), “123” company prefix, “4567” (extension number)


Although the E164 format definition, the iNUM Initiative left some recommendations. Most important are: The length of all these codes varies per country.

The address format can be International, – with or without leading (E123) notation, National or a private number format.


Resuming, depending on the requirements several combinations are possible, However, incorrectness results that calls are rejected.
