Stripping @domain for dialing to H.323 numbers

SIP endpoints can only make calls in the form of URIs - e.g.
name@domain. If the caller does not specify a domain when
placing the call, the SIP endpoint will automatically append its
own domain to the number that is dialed. So if you dial
a SIP endpoint, the search will be placed for 123@domain. If the
H.323 endpoint being dialed is registered as 123, then the VCS
won't be able to locate the alias 123@domain
fail.
If you have a deployment that includes both SIP endpoints and
H.323 endpoints that register using a number, you will need to
set up the following pre-search and local zone transforms. This
will enable users to place calls from SIP and H.323 endpoints
to H.323 endpoints registered using their H.323 E164 number
only.

Explanation
The pre-search transform takes any number-only dial strings (e.g.
123) and appends the domain used in endpoint AORs and URIs
in your deployment. This ensures that calls made by SIP and
H.323 endpoints result in the same URI.
123 from
Local Zones matches then make sure that both the E164
number and full URI are searched for, so that endpoints can still
be reached whether they have registered with an H.323 number
and the call will
(e.g. 123) or a full URI (e.g. 123@domain):

•
The first Local Zone match takes any aliases that are in the
format number@domain and transforms these into the format
number.
• To ensure that any endpoints that have actually registered
with an alias in the format number@domain
reached, a second Local Zone match must be configured at a
lower priority that will place calls to number@domain
transforming the alias.
