<p class=MsoNormal>During some internal prototyping of a FaxOut service an
issue was discovered. RFC3966 that specifies the “tel:” URI
scheme has a significant shortcoming. The RFC it replaced (RFC2806) that covered
the concept know as Dial Strings. Dial Strings are the actual numbers,
symbols, and pauses entered by a user to place a phone call. Also specified in
RFC2806 was the use of T.33 SubAddressing in a telephone or fax URI. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>RFC3966 explicitly excludes Dial Strings in the
specification leaving it for a separate undefined document to cover. To
the best of my knowledge no such document exists. My Internet Draft
proposal is for an informational RFC to specify the Dial String parameters we
require in an RFC3966 compliant encoding. Please take a look at the short
draft (7 pages including all the boiler plate text) and send any comments.
This specification will be reviewed in this week’s MFD phone conference.
