Santo,

This is an interesting problem.

However, as the E164 alias is a user dialed number, it will include such thing as "011" for international calls. However, if the call uses a foreign gateway, the gateway will not understand "011" as it is expecting "00" to indicate an international call so it will treat "0" as a national call and try to send the call to "11+". The structured values in partyNumber indication the unique number without any identification or routing information. Therefore a number indicated as an international number is valid anywhere in the world.

I like to see e164 alias being used. In order for an EP to send the new V2 aliases, it has to know that the destination is a V2 or higher. How does the caller know the callee is V2 or higher? Any thoughts?

What is the difference between an e164 alias and a partyNumber alias? Was e164 found lacking, and does partyNumber now supercede it? Are we supposed to stop using e164? If not, how do we decide which form to use?
