Minimum requirements for a Sametime 11.5 Meeting server
• Hardware
• Physical host or virtual machine with 8 CPU cores, 32 GB RAM and 500 GB HD
• Software
• Linux host with RHEL / CentOS (version 7.4+ and 8) or SUSE (version 12 and 15)
• Docker CE 19.03.8 (or latest)
• Kubernetes 1.16.0 (or later) with Ingress controller
• Helm 3.1.2
Sametime 11.5 Meeting server will be available for download on Flexnet only as a container image, i.e. NO
traditional installer package.
Running a Sametime 11.5 Meeting server on a Windows Server host (via Windows container support / WSL2)
may work…but is not supported at this time.

Deployment options for a Sametime 11.5 Meeting server
Intended for a small deployments
and POC type environments
Easiest to install and configure
Limited number of users
Does not support automatic scaling,
limited number of ‘recorders’
Fully supported for production
Intended for production deployments
Requires a customer to have a full
Kubernetes environment and experience
See also “Kubernetes Quick Start”
Supports autoscaling thru Kubernetes
This is the suggested and recommended
deployment model

Learn the basics: Kubernetes Quick Start
If you have never used Kubernetes…
The Sametime Kubernetes Quick Start document can help you set up a basic,
non-production cluster on RedHat Enterprise Linux or CentOS quickly.
It is intended only as an introduction to a Kubernetes based installation and to
familiarize the administrator with how to install and configure the Sametime
Meeting server.
This option is not intended for production usage, not even for a small
environment !

High-level overview of a Sametime 11.5 Meeting server installation
Install Docker (if not already present)
Unzip sametime_meetings.zip
Modify .env file for local settings
Run install.sh
Install Kubernetes v1.16.0 or later with Ingress controller
Install Helm v3.1.2
Unzip sametime_meetings.zip
Deploy the docker images (./load.sh)
Configure secrets (./generateSecrets.sh)
Create the recordings volume
Edit the global configuration (vi values.yaml)
Deploy the helm chart (helm install sametime-meetings .)
Prerequisite: Sametime 11.5 Community and Proxy server must be installed and configured
Configure Community and Proxy server
• Enable meeting feature in Policy (policies.user.xml - im.meetingsEnabled)
• Add JWT settings to Community and Proxy configuration

Sametime 11.5 Topology

Sametime 11.5 Meetings Network Considerations
Meeting Clients access the Meeting “center” (Meeting server home page) via https
• default port 443, can be changed if required
Meeting Clients use UDP port 30000 for the Media Streams
• Make sure all involved firewalls allow unrestricted UDP traffic on this port
Clients and Server use Google STUN servers to negotiate IP addresses when needed
• Sametime Meetings will utilize internet accessible STUN servers to help clients and the server negotiate media
paths for the exchange of audio/video/appshare data
• Public Google STUN servers are configured by default
• The configuration can be changed to use other public STUN servers instead
• Alternatively you can run your own STUN server
“Session Traversal Utilities for NAT (STUN) is a protocol that serves as a tool for other protocols in dealing with Network
Address Translator (NAT) traversal. It can be used by an endpoint to determine the IP address and port allocated to it by a
NAT. It can also be used to check connectivity between two endpoints, and as a keep-alive protocol to maintain NAT bindings.”

Authentication of end users
Sametime 11.5 Meetings rely on authentication from a Sametime 11.5 Community server
• Authentication request is routed from the Meeting server through the Sametime Proxy to the Community server
• Authentication is provided by the Sametime Community server
• SSO: Support for SAML and LTPA
There is no “standalone” Sametime 11.5 Meeting server.
External users can be authenticated or non-authenticated (B2B / B2C)
• External users can be maintained in a separate directory / separate LDAP tree for authentication
• Non-authenticated guest users only need to provide a name…any name
• You are responsible for adhering to license terms

Authenticated users vs. non-authenticated "guest" users
Non-authenticated guest users...
• …access a meeting via the meeting URL provided to them by a meeting owner (e.g. in a mail or calendar invitation)
• …participate in a meeting using a name of their choice
• …can share their screen or a selected application
• …can share a YouTube video
• …can participate in meeting chat but don’t have access to the chat conversation after the meeting has ended
• …can’t add other participants to a meeting
• …can’t initiate recording of a meeting
• …can’t initiate streaming of a meeting to a YouTube channel
• …can leave a meeting but cannot end a meeting for everyone

How does chat integration between Sametime 11.5 Meetings
and Sametime Chat work?
During the meeting the Sametime Meeting server talks to the Sametime Chat infrastructure
via the Sametime Proxy.
As a result an in-meeting chat automatically becomes a Sametime persistent chat.
• Authenticated users can follow along or lookup and continue the chat conversation after the meeting has ended
• Non-authenticated guest users only have access to the chat conversation during the meeting

Do you need system wide settings to
enforce or prevent the recording of
meetings?
Do you need granular control about
who is allowed to record a meeting?
Tell us your suggestions / requests:
https://domino-ideas.hcltechsw.com
Only the meeting host can record a meeting
• Server-side recording
• Generates MP4 video file by default
• Download link automatically appears in meeting list
and meeting chat
How does the recording of meetings work?
Recording meetings is an “expensive” operation
that can take considerable server resources.

Do you need system wide settings to
prevent live streaming of meetings?
Do you need granular control about
who is allowed to use live streaming?
Tell us your suggestions / requests:
Only the meeting host can start a live stream
• Server-side streaming from Sametime to YouTube
• Requires existing private or public YouTube channel
• YouTube generates a live stream key for authentication
• Chat on YouTube must be monitored separately
(no return channel into Sametime meeting chat)
• YouTube can also provide a recording of your live stream
How does live streaming work?

Which concepts can you use for scaling and high availability?
Increase the number of concurrent media streams / concurrent meetings
• Sametime 11.5 Meeting server has built-in autoscaling
• Sametime admin only needs to do inital config, Kubernetes detects and handles scaling on demand
Setup additional Meeting server(s)
• Allows for even larger number of concurrent meetings
• Keep aspects such as network infrastructure and location of attendees in mind
• Can also provide redundancy
Setup load balancing / failover across multiple Meeting servers
• Use this approach to make the Sametime Meeting “service“ as such highly available
• Only supported with Kubernetes based installations
There is no concept to provide complete & transparent failover for a meeting, that is already running.
While the meeting itself could be easily restarted, you would have to manually restart recording, live
streaming, etc.

Dial-in capability is already planned for
a future release.
What other SIP connectivity options do
you need?
Tell us about your use cases:
To add participants to a meeting via phone the Sametime Meeting
server must be connected to a SIP provider (e.g. your on prem SIP
based PBX or a SIP service provider on the Internet).
A meeting host can add additional participants to a meeting
• Provide phone number of additional participant
• Sametime Meeting will initiate an outbound call to bring in the
additional participant.
Adding participants to a meeting via phone
By using this method you can also add a Sametime 9 Connect
client, that is connected to a SIP infrastructure and used as a SIP
telephony endpoint, into your Sametime 11.5 meeting.
