RE: Resend - Telephone number URI's and SIP URIs for phone numbers

["Carl Reed OGC" <creed@opengeospatial.org>]

In particular, check:

 

http://www.ietf.org/html.charters/enum-charter.html

 

and more germane:

 

http://www.ietf.org/html.charters/iptel-charter.html

 

The latter specifically "The focus of the IP Telephony (iptel) group is on the problems related
to naming and routing for Voice over IP (VoIP) protocols.
Naming is accomplished through the use of the tel URI, which specifies
a URI for telephone numbers. The tel URI was originally defined in RFC
2806, which was developed outside of any IETF working group. The iptel
working group is responsible for updating the specification based on
extensive experience with the tel URI. It is chartered to develop any
extensions to the tel URI, such as support for number portability
indicators and trunk groups."

 

Also check the SIP (Session Initiation Protocol)  WG RFC's
