As shown in the table, Cisco Jabber uses a number of protocols for communication. In addition, these protocols may be used and are listed here for your reference:
- Port 7080: Protocol TCP (HTTPS); used for Cisco Unity Connection for notifications of voice messages (new message, message update, and message deletion)
- Port 37200: Protocol SOCKS5 Bytestreams; used for peer-to-peer file transfers. In on-premises deployments, the client also uses this port to send screen captures.
