Configuring Text-to-Speech Access to Exchange Emails in Cisco Unity Connection 9.x
The Text-to-Speech feature is supported when Unity Connection is configured for unified messaging. The text-to-speech feature allows the unified messaging users to listen to their emails when they sign in to Unity Connection using phone.
Unity Connection supports text-to-speech feature with the following message stores:
Note Text-to-speech over Exchange 2007, Exchange 2010, and Exchange 2013 supports both the IPv4 and IPv6 addresses. However, the IPv6 address works only when Unity Connection platform is compatible and configured in dual (IPv4/IPv6) mode.
Task List for Configuring Text-to-Speech
Follow the given steps in the order given to configure text-to-speech feature for Unity Connection users:
Step 1 Unity Connection uses the IMAP protocol to access emails in Exchange so that the messages can be played using TTS. By default, Exchange is not configured to allow IMAP access to messages. To enable IMAP access to Exchange emails:
a. Sign in to the Exchange server using an account with Local Administrator group, This Exchange server contains the emails you want licensed voicemail Unity Connection users to access .
b. On the Windows Start menu, select Administrative Tools> Services. Then select Microsoft Exchange IMAP4 service.
c. Open the Microsoft Exchange IMAP4 Properties dialog box. Make sure the value of Status column is set to Started and value of Startup Type column is set to Automatic. Select OK to save changes.
d. Repeat the same steps for all Exchange servers that contain emails the unified messaging users want to access.
Step 2 Follow the steps depending on the Exchange server that has the mails the unified messaging users want to access:
Step 3 Enable text-to-speech in Unity Connection on an existing or a new unified messaging service.
a. Navigate to Cisco Unity Connection Administration and select Unified Messaging> Unified Messaging Services.
b. Either select an existing unified messaging service or create a new selecting Add New.
c. On the New Unified Messaging Service page or Edit Unified Messaging Service page, enter all the required details. Under Service Capabilities, make sure the Access Exchange Email Using Text to Speech (TTS) check box is checked.
Note For a new unified messaging service, make sure that unified messaging feature is properly configured on Unity Connection as per the Unified Messaging Guide for Cisco Unity Connection Release 9.x at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/9x/unified_messaging/guide/9xcucumgx.html.
d. Select Save.
Step 4 Under Licensed Features, make sure the class of service assigned to the unified messaging users has the Allow Access to Exchange Email Using Text-to-Speech (TTS) check box checked .
Steps to be followed on Exchange 2013, Exchange 2010, or Exchange 2007
Create and install an SSL certificate on each Exchange server that unified messaging users want to access following the given steps:
1. Open the Exchange Management Shell on the Exchange server.
2. Enter the following command, where <Exchange server> is the IP address or host name of the Exchange server and <friendly name> is the friendly name that you select for the Exchange server:
new-exchangecertificate -generaterequest -domainname <Exchange server> -friendlyname <friendly name>-path c:\csr.txt
Caution The domain name for the Exchange server must be the IP address or the fully qualified DNS name (recommended) so that the Unity Connection server can successfully ping the Exchange server. Otherwise, users may not be able to access their emails in the external message store.
3. Press the Enter key and a Certificate Signing Request (CSR) file with the name Csr.txt is created in the root directory.
4. Send the CSR file to a Certification Authority (CA) that generates and sends back a new certificate.
Note You must have a copy of the CA public root certificate or public root certificate chain. This certificate is needed for configuring Unity Connection to trust the Exchange 2013, Exchange 2010, or Exchange 2007 server.
5. Enter the following command, where <path> is the location of the directory where the CA saves the new server certificate:
import-exchangecertificate -path <path>
6. Press the Enter key and enter the following command:
dir cert:\localmachine\my | fl
7. Press the Enter key and highlight the “thumbprint” property and copy it to the clipboard.
8. Perform either of the following actions:
a. If the class of service for unified messaging users is configured to access email and use calendar data from an external email server using IMAP, enter the following command:
enable-exchangecertificate -thumbprint <thumbprint> -services "IIS,IMAP"
b. If the class of service for unified messaging users is not configured to access calendar data from external email server using IMAP, enter the following command:
enable-exchangecertificate -thumbprint <thumbprint> -services "IIS"
9. Press the Enter key.
Steps to be followed on Exchange 2003
Creating and Configuring Active Directory Service Account
Create an Active Directory service account that acts as a proxy for Unity Connection and allows to access emails from an Exchange server. Follow the given steps:
