Note: OCS does not accept INVITEs with no SDP; it requires the calling party to choose the audio
and video codecs. When interworking an H.323 call to Microsoft OCS 2007, Cisco VCS offers a
default set of codecs. By default Cisco VCS chooses a sensible audio and video codec for OCS, but
see Appendix 6 – Setting default codecs for H.323 to SIP calls if it is desired to modify the codecs
offered in the initial INVITE of an interworked call.

Set up a Search rule to select what gets routed to the OCS zone
Search rules are used to specify the URIs to be forwarded to this neighbor OCS (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 calls” for
further information about user=phone).

For this scenario, anything with a domain test-customer.com will be matched (and passed to OCS); no
