Voice interface must be shutdown before updating configuration
Here, you can also enable Mailbox creation, set a specific user as an Administrator or set CFNA/CFB (Call Forward No Answer / Call Forward Busy) so that incoming calls to the user are directed to his/her voicemail when not answered or busy: Clicking on Next takes us to the Defaults page where default settings are configured for all new users and mailboxes created from now on.Ensure the System Default Language is set to English (in most cases) and take note of the Password & PIN Options.
This configuration method is known as ‘Router on a Stick’ and allows all configured VLANs to pass through a single interface.It is a common practice to configure Unity Express with an IP address that is part of the Voice VLAN, that is, 192.168.10.0/24 in our example: In the above configuration commands, we’ve configured our Unity Express module with IP address 192.1 and a default-gateway of 192.168.10.5 (CCME’s Voice VLAN IP address), this is because the Unity Express module is physically connected to our router’s internal interfaces (ISM) and therefore must use one of the router’s IP interfaces as a default-gateway.The ip unnumbered command allows the Cisco Unity Express module to use a network subnet IP address associated with a specific router egress port such as Gigabit Ethernet0/0.2.Using the username and password entered above, we log in to the Unity Express administration panel: Upon logon, we need to select the appropriate Call Agent Integration from the drop-down menu, in our case Cisco Unified Communication Manager Express: After the selection, the system will warn that it will delete Jtapi related configuration and reboot.Do not be alarmed and click on OK to continue: If you’re connected to the unity express CLI, you’ll also be able to view the whole reboot process.For the SRE-300, the module’s interface name is interface ISM0/0, whereas for the SM-SRE-700 it is service-module sm2/0.
Both interfaces are Gigabit Ethernet, connected via each router’s internal bus.
This screen is to provide the credentials so that Unity Express can log on to the CCME and obtain user account configuration.
This account is the same account created under the Telephony-Service section of CCME (shown previously).
Here is the session we captured during this reboot: While Unity Express reboots, the GUI interface shows a messaging explaining that the system is reloading and will automatically try to reconnect once the reboot cycle is complete: When the system is back online it is necessary to log back in using the Unity Express administrator account previously created (admin).
After the logon process is complete, we are presented with the CUCME Logon screen.
First step is to configure IP connectivity between the router (CCME) and Unity Express.
