Essential installation and upgrade information for Mitel CX version 1.1.0.0
The Mitel CX version 1.1.0.0 upgrade must be installed on top of MiContact Center Business Version 9.4.1.0 or above, 9.5.X.X, or 10.X.X.X through 10.2.0.6. This release contains defect fixes and features that are available only with Version CX 1.1.0.0.
If you are performing a side-by-side migration as part of your upgrade, please see the following Knowledge Management System article for more information: https://mitel.custhelp.com/app/answers/answer_view/a_id/1011100/loc/en_US
Before upgrading, we recommend you create a backup of your configuration and telephone system data. This provides data protection in case there are unexpected issues while upgrading from one version of MiContact Center to another.
To back up telephone system and configuration data
- In Contact Center Client, click Tools=>Management.
- In Management Console, click Configuration=>Back up/Restore configuration data.
- Select Back up and click Next.
- Next to Save, click the drop-down button and select Save as.
- Select a location to save the file and click Save.
- Close the View Downloads window and, in the Backup and Restore Wizard, click Finish.
A .zip file is created that contains an XML file with the entire configuration. The file size will vary depending on the amount of data that needs to be backed up. This .zip file name contains the date on which the file was created. For example, a backup file created on June 24, 2015 will contain '20150624'.
Please note the following:
- The Enterprise Server and clients must use the same version of Mitel CX. After updating the Enterprise Server with the current release, all clients in your contact center must also be updated. Client updates in Version 1.1.0.0 are approximately 700 MB. For information on the estimated bandwidth costs for updating clients, see the Mitel CX System Engineering Guide. If the MiContact Center Updater Service has been disabled on clients, the clients must be updated manually.
- Microsoft .Net 4.8 is required. This will be updated automatically on the main MiContact Center Business server, but must be installed manually on any Client PCs and remote IVR servers.
Before upgrading third-party software applications, confirm the application is supported for integration with your version of MiContact Center and Business Reporter. For information concerning support for third-party software applications, see the Mitel CX System Engineering Guide.
As a best practice, we recommend you stay up to date with the most current releases of the Mitel telephone systems you use in your business. The following table details support for Mitel telephone systems by version. For complete details on the features and functionality supported by each telephone system, see the Mitel CX System Engineering Guide which can be found at http://edocs.mitel.com.
If you are installing Mitel CX with a MiVoice 5000, OpenScape Voice or OpenScape 4000 and you have configured over 1200 voice agents, please see KMS article HO5497 for details on how to improve monitor registration time.
NOTE: Multiple VLAN configurations, available as of MiCD 1.2, are not supported.

Known issues
The following section describes known issues in Mitel CX version 1.1.0.0.
| Tracking Number | Description |

| 411666 | Within the Contact Center Client or Web Ignite, you cannot dial a queue group directly. You need to dial a specific queue within that group. |
| 418269 | When an abandoned callback request to a callback queue is submitted outside of business hours, the request time does not follow the "CallbackNextRequestInMinutes" variable. |
| 421670 | In Web Ignite, taskbar notifications no longer work in Chrome is your Chrome browser is version 62 or higher if you do not have SSL configured on your Enterprise server. This is because of security changes within the Chrome browser itself. |
| 423774 | In Web Ignite, if, during a conference call, the original caller hangs up first, the participants list is not updated to reflect the caller has left. |
| 424259 | It is possible in certain situations that an agent could be credited with an outbound call if the agent receives an ACD call and performs multiple swaps and holds. |
| 425645 | Web Ignite - After the first swap, agent state stays ACD instead of ACD Hold. |
| 425980 | An employee can still log in to Ignite (Desktop or Web), if the security role option "May access Contact Center Client and Ignite" option is unchecked. |
| 426269 | Contact Center Client stops responding for a long period of time when large number of emails are being deleted from IVQ at once. |

| 458551 | E.164 formatted numbers are not supported in Desktop Ignite. |
| 479630 | The Performance by Period reports will double-peg conference counts when all parties involved exist on a single MiVB as the raw data currently lacks Call IDs for linking. |
| 491751 | The "less than" character (<) is not supported in Text To Speech prompts. Including it will not playback and result in a logged parsing error. |
| 491784 | On remote nodes the Start Menu folder for Mitel is not created. |

| MICCB-7541 | Outbound CLIP not working with SIP platforms. |

| MCX-3177 | A user set to on demand recording in the CMS who makes an Outbound call to External number may have no call recordings if the call goes out through a different MiVB that the user is on (clustered MiVB's). |
| MCX-3154 | CMS Call Recording for MiVB- If an internal extension that is not part of YSE and not monitored on CMS dials a CX IVR and reaches a monitored WebIgnite Agent who has Agent Greeting enabled, only the agent greeting is recorded and not the rest of the call. |
