[SIPForum-techwg] Quetion about how registration mode works

So...to be clear, the current draft DOES allow email addresses for Main or Alternate enterprise public identities...

>From Section 9:
------------------------------------------
The SIP-PBX MUST allow the Service Provider to assign Enterprise Public Identities in any of the following forms:


 *   A SIP URI containing an E.164 number, the domain name of the Enterprise Network, and the "user=phone" parameter.

For example:

SIP:+16132581234@[domain name];user=phone


 *   An "email-style" SIP URI containing a user and a domain name (without a "user=phone" parameter).

For example:

SIP:JoeSmith@[domain name]

or

SIP:16132581234@[domain name]

-------------------------------------------------------------

So...I'm confused by the etrail below...is this section being debated now?  Or has it been misrepresented in the response to Cullen?

Regards,
JBP

Because frankly no one cares about email style URI's. What we are dealing
with here is the real world where E.164 means a voice service and people are
trying to create profitable service offerings.
