Cisco Cisco Expressway

Set up search rules to route calls to any other domains supported on
Lync (but not in the video network) to Lync

If Lync supports only a single domain then no other search rule is required here. If Lync supports other
domains and video endpoints should be able to call these devices, one or more additional search rules can be
added.

1. Go to

Configuration > Dial plan > Search rules

2. Click New.

3. Configure the search rule so that all calls to the relevant URI are routed to Lync.

Rule name

xxxx To Lync

Priority

100

Source

Any

Mode

Alias pattern match

(never use a Mode of Any alias)

Pattern type

Regex

Pattern string

.+@<relevant domain>.*

Pattern behavior

Leave

On successful match

Stop

Target zone

To Microsoft Lync Server via B2BUA

4. Click Save.

5. Repeat for all domains supported on Lync (that are not used in the video network).

Calls can now be made between SIP endpoints registered on the video network to Lync clients registered on
Lync Server.

Testing the configuration

Test calls from endpoints registered on the video network to Lync clients registered on Lync Server.

For example, call david.jones@ciscotp.com or alice.parkes@ciscotp.com from endpoints registered on
Unified CM.

Note that if Lync for Mac OS X is used and a Cisco AM GW is not installed, the call will result in an audio only
call as Lync for Mac does not support any video codecs supported by standards-based endpoints.
