Title: Using E.164 numbers and other comments

I wasn't able to listen to the conference call so some of this might be repetition.

I don't see where regulatory implications is a problem if a person where to use e.164 numbers or not.  The first time someone trys to call 911on a system that doesn't get routed to the right place seems to be where the fcc sticks their hands into the mess.  In addition, as moves forward and get larger it might not fly "under the radar" of the regulators anymore.

The "Seamless Interoperability with PSTN" might  be considered really minimum rather  than a con.  Say during a pure sip to sip call the person then has the ability to be doing video, and presence, etc.  Also, some of the bonuses might not be seen until the end of the month bill arrives.

In addition, by using e.164 numbers failover/fall back to pstn automatically, in case something dies.   In addition to failover/fall back to pstn there is the other direction of the pstn failing and thus one would route everything via sip.

How much training is the typical enduser going to need to use it? Will they use it?  Current pstn setups are easy to do the minimum requirements of communication  from person to person.  Also, what works on the pstn works on the cell phone.

As an alternative to using formal e.164 numbers, how about looking at what the people at are doing for campus and endpoint numbering when trying to use h.323.
