Search rules are used to specify the URIs to be forwarded to OCS/Lync (for example, by matching the
domain of the destination or by matching some element in the URI).

Search rules can also be used to transform URIs before they are sent to a neighbor, for example to
add or modify the domain or add, remove or translate user-id prefixes and even to add extra tags to
SIP URIs, such as user=phone (see “Appendix 8 – TEL URI handling for Cisco VCS to OCS/Lync
calls” for further information about user=phone).
