Ports used by Sametime services

Sametime services use several ports for communication. If firewalls are in use in your environment, all traffic on these ports should be permitted bidirectionally.

Table 1. Ports used by Sametime services
Port Number Description
389 Used for non-secure communications from the Sametime server to the LDAP server.
443 Used for HTTP communications over a secure connection.
636 Used for secure communications with LDAP for directory services.
1516 Used as an internal port between the community and proxy pods.
1533 Used to listen for direct TCP/IP connections from Sametime Connect clients.

A direct TCP/IP connection is when a Sametime client uses a unique Sametime protocol over TCP/IP to establish a connection with community services.

1935 Used when streaming YouTube videos.
5280, 5222 Used to reach the service cluster IP for Jitsi.

In Kubernetes environments, for websockets to function properly, the video pods using the node port must be able to reach the service Cluster IP for Jitsi on ports 5280 and 5222. See the Websockets fail to load after installing Sametime 11.6 or 12.0.x on Kubernetes article for more information.

8000 Used to listen for HTTP communications. All communication over this port is redirected to HTTPS port 443. Port 8000 is the default port assigned during the product installation process.
10000 Used by audio and video clients to stream media data when deploying Sametime on Docker.
19302 This UDP port is the default STUN port used by both the client and meeting server for NAT traversal.
27017 Used for communication with MongoDB.
30000 Used by audio and video clients to stream media data when deploying Sametime on Kubernetes.
