For example, when alice.parkes@example.com is called, the call will fork to the Lync client with the same name, and
also to alice.parkes.office@video.example.com and alice.parkes.home@example.com (assuming that these two
devices are listed as primary devices in Alice Parkes’ FindMe.)

We strongly recommend that you create users on Lync first and have them sign in at least once from a Lync
client. You can create the FindMe accounts 5 to 10 minutes later on the Gateway VCS (when the user is fully

TEL URI Handling for VCS to Lync Calls
If an endpoint wants to dial a telephone number rather than selecting a user from a directory, the VCS Control must
format the telephone number appropriately for Lync to be able to look it up. Lync expects to see telephone numbers
(known as TEL: URIs) in the form:
format the telephone number appropriately for Lync to be able to look it up. Lync expects to see telephone numbers
(known as TEL: URIs) in the form:
+<country code><full dialed number>
VCS Control can use transforms to appropriately format the telephone numbers. These transforms can either be
implemented globally using Configuration > Dial plan > Transforms or just for the Lync neighbor zone or B2BUA
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 the UK
whose telephone number is 781xxx, an extension number 1008 would need to be expanded to +441344781008. This
can be implemented by configuring a transform as follows:
whose telephone number is 781xxx, an extension number 1008 would need to be expanded to +441344781008. This
can be implemented by configuring a transform as follows:
