CUCM-CUE SRST

When integrating CUCM with CUE, you need to consider the functionality of CUE during SRST mode. The methodology is to use SIP triggers on CUE with dialpeers configured on SRST router pointing to CUE as per below configuration. In fact you will be configuring CME-CUE integration to be used in case of SRST.

CME Integration with CUE

Step 1 Activate the network connectivity to CUE from the CME router.
int ISM0/0 ip unnumbered GigabitEthernet0/0.34 service-module ip address 10.34.x.251 255.255.255.0 service-module ip default-gateway 10.34.x.1 no shut ! ip route 10.34.x.251 255.255.255.255 ism0/0
Note: For 'ip unnumbered' command to work, you need to make sure that 'proxy-arp' is enabled on the original interface.
Step 2 Configure a dial-peer on the CME router for CME phones to call voicemail number. CUE interface with CME is using SIP protocol only whether you are using SCCP or SIP CME.

CUCM Integration with CUE

Image
CUCM integrates with CUE through JTAPI protocol for voice mail and automated attendant functionality.
The CUE is able to register with the CUCM through JTAPI and controls CTI Route-Points and CTI Ports. This allows you to control and manage the CUE as an additional endpoint through the CUCM, as well as facilitate the configurations and interactions with other endpoints in the cluster.
What are CTI Ports? CTI ports are virtual lines that can send and receive audio but are controlled through the JTAPI protocol by CUE.
What are CTI Route Point? CTI route point is a virtual device controlled by CUE. The CTI route point can receive multiple simultaneous calls and redirect them to the CTI ports configured earlier.
