This topic describes the different ports that Cisco Jabber uses to communicate.

|Port|Protocol|Description|
|53|UDP/TCP|DNS traffic|
|69/6790|UDP|TFTP/HTTP Config Download|
|80/443|TCP|HTTP/HTTPS to Cisco Unity Connection or WebEx|
|143|TCP|IMAP (TLS or plain TCP) to Cisco Unity Connection|
|389/636|TCP|LDAP/LDAPS|
|993|TCP|IMAP (over SSL) to retrieve and manage voice messages|
|2748|TCP|CTI gateway|
|3268/3269|TCP|Global Catalog/LDAPs|
|5060|UDP/TCP|SIP call signaling|
|5061|TCP|Secure SIP call signaling|
|5070|UDP|Binary Floor Control Protocol (BFCP) for video desktop sharing|
|5222|TCP|XMPP|
|7993|TCP|IMAP (over TLS) access to secure voice messages|

CTI = computer telephony integration; DNS = Domain Name System; IMAP = Internet Message Access Protocol; LDAP = Lightweight Directory Access Protocol; LDAPS = Lightweight Directory Access Protocol over Secure Sockets Layer/Transport Layer Security; SIP = Session Initiation Protocol; XMPP = Extensible Messaging and Presence Protocol.

|Port|Protocol|Description|
|8191|TCP|SOAP web services|
|8443|TCP|HTTPS for CCMCIP profiles and UDS|
|16384-32766|UDP|RTP media streams for audio and video|

CCMCIP = Cisco Unified Communications Manager IP Phone service; RTP = Real-Time Transport Protocol; SOAP = Simple Object Access Protocol; UDS = User Data Service.

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.
