If an endpoint wants to dial a telephone number rather than selecting a user from a directory, the
Cisco VCS Control must format the telephone number appropriately for Lync Server to be able to look
it up.
Cisco VCS Control must format the telephone number appropriately for Lync Server to be able to look
it up.
Lync Server expects to see telephone numbers (known as TEL: URIs) in the form:
+<country code><full dialed number>
Cisco VCS Control can use transforms to appropriately format the telephone numbers. These
transforms can either be implemented globally using VCS Configuration > Dial plan > Transforms
or just for the Lync Neighbor zone by configuring the transform in the appropriate Search rules.

For example, for 4 digit extension number dialing to be expanded to a full telephone number for a
company in Bracknell UK whose telephone number is 781xxx, an extension number 1008 would need
to be expanded to +441344781008.

to be expanded to +441344781008.
For a non OCS Relay system this can be implemented as follows:
Priority
80
(match in preference to the no transform needed rule - 80 is higher priority
than 100)
