Subject: [Enum] One-way or return-ticket ?

Hello.

Are there any ideas, whether a Sip/H.323 Enum caller should
give its Fully Qualified E.164 Number as calling party information 
or its protocol dependent Uri ? Or maybe both ?

If someone is calling out by means of ENUM, shouldn't he/she indicate
ENUM-reachability ? What shall be present in the call-list of the 
call-recipient's IP-phone ?

Eg. H.323 allows for both types of information, a numerical calling 
party number (e164) and an H.323-URL, as well. The e164 would serve as
key into the backward ENUM query - provided it's fully qualified.
e.g. for a german no.:
e164=49 123 4567 89
url-Id=h323:[email-masked]

What's it for Sip ?

Regards Martin
