1. ENUM Privacy and Security issues http://www.ietf.org/internet- drafts/draft-ietf-enum-privacy- security-00.txt

2. What is ENUM SCP Called party control of a session Calling party control of a session

3. ENUM Privacy What data must be collected to insert into the DNS. –How is that data presented? What data is necessary for ENUM registration. TBD

4. ENUM Security Security of the DNS Security of the provisioning process –provreg TBD

5. Calling party control Calling party wants the maximum # of options available to select from. DNS can be used to present them $ORIGIN 4.3.2.1.6.7.9.8.6.4.e164.arpa. IN NAPTR 100 20 "u" "E2U+voice:sip:home” "!^.*$!sip:patrik.faltstrom@foobar.se!" IN NAPTR 100 10 "u" "E2U+video:sip:home” "!^.*$!sip:patrik@carrier.biz!" IN NAPTR 100 50 "u" "E2U+sip” " !^.*$!sip:faltstrom@carrier.se!“ IN NAPTR 100 40 "u" "E2U+im:sip" "!^.*$!sip:lapan@bigsoftwareco.com!" IN NAPTR 100 10 "u" "E2U+email” "!^.*$!mailto:faltstrom@dorame.se!" IN NAPTR 100 50 "u" "E2U+fax" "!^.*$!mailto:patrik@fasolaredo.se!" IN NAPTR 100 10 "u" "E2U+tel:fax" "!^.*$!tel:+4689765444!" Fine if you are a real estate salesman

6. Called Party control Called Party wants maximum control and minimum exposure in the DNS Personal Identifying Information obscured $ORIGIN 4.3.2.1.6.7.9.8.6.4.e164.arpa. IN NAPTR 100 10 "u" "E2U+sip" "!^.*$!sip:4689761234@foobar.se!" OR $ORIGIN 4.3.2.1.6.7.9.8.6.4.e164.arpa. IN NAPTR 100 10 "u" "E2U+sip" "!^.*$!sip:anon5613@foobar.se!" SIP can negotiate a session One session negotiates for all services

7. What goes is the enumservice field and why? What is are legitimate field to establish a voice session between 2 endpoints? DDDS suggests parsing the service field in the NAPTR record before processing the regexp –What is the easiest to parse? E2U+sip:video E2U+sip:im E2U+sip:voice E2U+voice:sip Implementers need to know..all the drafts including 2916bis are ambiguous on this.

8. The complexity of tel: tel:voice tel:voice:mobile tel:fax tel:sms route to GW tel:tp (text phone)

9. So E2U+foo:foo:
