Configuring telephone URI verification for Blueworx Voice Response

CCXML and VXML specify the use of a "telephone URI" that should conform to RFC 2806.(http://www.ietf.org/rfc/rfc2806.txt). For example: .
CCXML <createcall> "dest=" attribute.
VXML  <transfer>   "dest=" attribute.
CCXML dialog.transfer event.
CCXML <redirect>   "dest=" attribute.
The information given here explains how RFC 2806 is implemented for CCXML and VXML on Blueworx Voice Response, and should be read in conjunction with RFC 2806.
