When the client connects to Cisco Unity Connection on a device that has antivirus software, users can have issues with voicemail connections. To resolve this issue, add the Cisco Unity Connection server information to the exceptions list for the antivirus software.

Users in Common Identity

There is a known issue signing into Cisco Jabber for some users who have migrated to Common Identity. If users receive an Incorrect user name or password error message when entering their username and password, see the following knowledge base article

Creating and Configuring Devices for Users in Cisco Unified Communications Manager 11.0

If you are creating devices for users in Cisco Unified Communications Manager 11.0, you can now specify a key order as RSA Only, EC Only or EC Preferred, RSA Backup. However, the EC Only option is not supported by Cisco Jabber, and if you select it, the client fails to connect to the server.

Certificate Validation for CTI Connections

Cisco Jabber uses certificate validation for CTI connections. We recommend using either Public CA or Private CA to sign certificates.

Connecting to Cisco Unified Communications Manager using a self-signed certificate, results in a certificate validation failure, to resolve this issue do one of the following:
  • The user accepts the invalid Cisco Unified Communications Manager self-signed certificate on first certificate validation failure and Cisco Jabber saves this certificate to the trust store.

  • Deploy the certificates using a certificate deployment management application.

Expressway for Mobile and Remote Access Deployment

For an Expressway for Mobile and Remote Access deployment, when using an online certificate status protocol (OCSP) or online certificate revocation lists (CRL) to obtain the revocation status of the certificates, the Cisco Jabber client expects a response time of less than 5 seconds. Connections will fail if the response time is greater than the expected 5 seconds.

Network Disconnection When Using Cisco Jabber on Audio or Video Call

There is a known issue in the Mac OS where network interfaces drop intermittently when DSCP is enabled.

If you encounter this issue, do the following:
  1. Select Preferences > Calls > Advanced.
  2. Uncheck Enable Differentiated Service for Calls.

Standard CTI Secure Connection User Group

Cisco Jabber for Mac does not currently support CTI connections over transport layer security (TLS). As a result, Cisco Jabber for Mac users cannot switch from using a CSF device to using a desk phone device if they belong to the Standard CTI Secure Connection user group.
