CUE Basic Integration with CME

Here are all the steps to perform if you want to integrate the CUE with the CME

  1. Create a SIP dial peer pointing to the CUE Module
  2. Configure the MWI On/Off extensions
  3. Configure the connectivity between CME and CUE Modules
  4. Perform CUE Configuration

For the first step , your dial peer will look like

dial-peer voice 1000 voip
destination-pattern 5555
session protocol sipv2
session target ipv4:
dtmf-relay sip-notify
codec g711ulaw
no vad

The configurations of the MWI On/Off must be generic as it must cover all numbers and it is generally implemented as a kind of prefix as the MWI must know which number must be turned on or off. So it adds the number after the extension the MWI shortcut.

ephone-dn 50
number 5000….
mwi on
ephone-dn 60
number 6000….
mwi off

Regarding the link configuration between the CUE and CME, you need to borrow the Ethernet interface where the CUE module resides (don’t forget that CME and CUE can be splitted). So everything under the service-engine ( this is the CUE module) will rely on the Ethernet interfaces:

interface Service-Engine 1/0
ip unnumbered FastEthernet 1/0
service-module ip address
service-module ip default-gateway
ip route Service-Engine1/0

In a multi-site implementations , you have then to configure a translation between your remote CME and the central CUE/CME because we told before that CUE relies on SIP Protocol and the rest of your network is an H323 network , so you need to translate all H323 request to SIP. You can do it generally with the config:

voice service voip
allow-connections H323 to sip

CUE : Quick Definition

CUE is as the CME a small business voice mail solution that you can easily deploy on a router. Most of the time, CUE will reside on the same chassis than the CME but for some implementations, you can split both. The only backdraw is that you must have a LAN connectivity between your elements.

CUE is interesting because it doens’t provide only voice mail but can also provide a small Auto-Attendant (AA). The integration between CUE and CME is done via the SIP protocol, while the integration with a Call Manager will be done via JTAPI ( CTI-QBE). It can be the case for implementation where you need to provide Unity backup on SRST location).

CUE will be supported by Network Module (NM-CUE) or as an Advanced Integration Module (AIM-CUE).

CME Integration with Cisco Unity

CME can be integrated with Cisco Unity, it is more or less as an integration with Call Manager except the fact that you must every setting in the CLI mode. Let’s see a kind of basic config:

voicemail 5555
ephone-dn 10
number 1234
call-forward busy 5555
call-forward noan 5555 timeout 10
ephone-dn 16
number 5566
mwi on
ephone-dn 17
number 5577
mwi off
ephone-dn 20
number 5555
name “VM-Port 1”
preference 0
no huntstop
ephone-dn 21
number 5555
name “VM-Port 2”
preference 1

no huntstop
ephone-dn 22
number 5555
name “VM-Port 3”
preference 2

no huntstop
ephone-dn 23
number 5555
name “VM-Port 4”
preference 3

ephone 20
vm-device-id “CISCOUM-VI1”
button 1:20
ephone 21
vm-device-id “CISCOUM-VI2”
button 1:21
ephone 22
vm-device-id “CISCOUM-VI3”
button 1:22
ephone 23
vm-device-id “CISCOUM-VI3”
button 1:23

So you can easily see that your config is trying to match the Unity port name and this is done with the command vm-device-id <<string>>. It helps also to register with Unity where you need the deviceId instead of a mac-address.
