In this deployment scenario, users want to be able to dial other endpoints registered to the Cisco VCS
Control using either an 11-digit E.164 number (01189 124 xxx) or a 4-digit extension number (4xxx).
CUCM endpoints are to be dialed using a 4 digit number (3xxx). This dialing model can be supported
by H.323 (if the endpoint registers both 4-digit and 11-digit E.164 aliases), however, SIP does not
support dialing by numbers alone. If a number (without a domain appended) is dialed from a SIP
endpoint the endpoint will automatically append its own domain.

For consistency with both SIP and H.323 dialing, this deployment scenario always uses the URI form
for routing calls (that is, dialed_digits@domain).

For call requests received by the Cisco VCS Control the dialed number:
may or may not include the first 7 digits of the 11-digit (Cisco VCS registered endpoint) number
- (not included when just the 4-digit extension number is dialed)

Transforms are needed to ensure that the dialed number (in whatever format it is received) is
transformed into a consistent form, in this case:
