QuestionQ228

Protocols and Endpoints

After an administrator installs the Cisco Jabber client, it does not register with the Cisco UCM server. Which two actions should be performed to troubleshoot this issue?

Choose two
  • A Verify the installation of the LMHOST file on the PC.
  • B Verify Layer 3 connectivity on the gateway.
  • C Verify corporate firewall settings for client connections.
  • D Verify the configuration of the DNS SRV record.
  • E Reboot the Cisco Unified Border Element Gateway.
Explanation

Cisco Jabber must be able to discover Cisco Unified Communications Manager services through the applicable DNS SRV record, so the DNS SRV configuration must be verified. Any firewall between the Jabber client and its servers must also permit the required client-to-server ports and protocols; blocked traffic can prevent service access and registration.
