With ISDN service, DNIS presents the "DID" number, 222-222-2222 in the
example--not what Soonthorn is looking for.
111-111-1111 is the "redirecting" number. This is available in an ISDN
information element.
For SIP, you'd apparently look for a "CC-Diversion header field." This is
from a Cisco blurb:
If generated by the SIP gateway during call process, the CC-Diversion header
field is based on the contents of the Redirecting Number Information Element
(IE) in the ISDN Setup message. In addition, information such as the reason
the call was redirected is included in the CC-Diversion header field.

Hello,
Maybe what you are looking for is called DNIS (Dialed Number Information
Service). Some companies provide this service, which you can use to
route incoming calls to different dialplan options/contexts/etc.
