Cisco Cisco Expressway
Milestone 1: Test Calls From Cisco Jabber to Microsoft Client
Figure 7 Test SIP Call From Cisco Jabber to Microsoft Client
1.
Cisco Jabber user makes call to known alias in the Microsoft client's domain.
2.
CUCM routes the call on the trunk to Expressway-C.
3.
Expressway-C receives call on CUCM neighbor zone, transforms destination string if necessary, and routes on
neighbor zone to FE Server.
neighbor zone to FE Server.
4.
FE server receives call from trusted application and routes it to the destination alias.
5.
Microsoft client answers.
Task 5: Configure Expressway-C to Route Calls From Microsoft Hosts
1.
On the Expressway-C (primary), add a trusted host for each Microsoft Server that will route towards
Expressway-C.
Expressway-C.
2.
Create a neighbor zone to each CUCM with these parameters:
Port = 5061, Transport = TLS enabled, TLS verify mode = On, Authentication trust mode = Off.
3.
Create search rules to route calls from Microsoft Interoperability zone to CUCM zones.

Task 6: Create Static SIP Route From Microsoft FE Server
1.
Create a new static TLS route with the following parameters:
MatchURI = CUCM domain (same as MS domain), port = 65072, destination = Expressway-C cluster FQDN,
use default certificate = true.
use default certificate = true.
2.
Assign the route to the global routing configuration.
3.
Enable the topology.
