In-Depth Information
These ephone-dns correspond to the numbers that CUE dials to turn MWIs on and off. Notice that the numbers specify wildcards
(8000...., 8001....); this allows CUE to call the number and append the extension whose MWI should be turned on or off.
For example, if a message is left for extension 1001, CUE dials 80001001 and that causes CME to turn MWI on for extension 1001. If
all messages have been listened to and the MWI must be turned off, CUE dials 80011001 and CME turns the MWI off.
The following example shows the configuration of IP connectivity for CME/CUE:
interface Service-Engine
1/0
ip unnumbered
FastEthernet1/0
service-module ip address
10.1.1.5 255.255.0.0
service-module ip default-gateway
10.1.1.1
!
ip route
10.1.1.5 255.255.255.255
Service-Engine
1/0
The
ip unnumbered FastEthernet1/0
command configures an IP address on the CME router's internal interface to CUE. In this
example, the IP address is “borrowed” from interface Fast Ethernet 1/0 (10.1.1.1).
The
service-module ip address
command is then used to configure an IP address for the CUE module (10.1.1.5).
The next command is
service-module ip default-gateway
. This configures the default gateway (10.1.1.1) for the CUE module.
Finally, the
ip route 10.1.1.5 255.255.255.0 Service-Engine1/0
command is used to configure a route from CME to CUE via
interface Service Engine 1/0.
In a multisite environment, calls between the sites use H.323, but calls to CUE use SIP. This means that H.323 to SIP translation is
needed on CME:
voice service voip
allow-connections h323 to sip
The
voice service voip
command enters voice service configuration mode and specifies VoIP encapsulation.
The
allow-connections h323 to sip
command allows connections between H.323 and SIP endpoints (CME/CUE).
