Introduction
“Federation” is the process and technology that supports external communication and
collaboration via IM, Presence, Audio and Video including Content Sharing, with users outside
an organizations own domain. Microsoft® Lync™ “federation” enables external users in other
public and/or private Lync SIP network domains to collaborate with external users using the
Microsoft Lync client application.
An enterprise must deploy a Lync Edge Server outside the enterprise firewall so that signalling
(SIP) and media (Audio, Video, content sharing, IM, and presence) connections can be
established from within the internal enterprise Lync deployment to other external public and/or
private Lync deployments – including the jamvee™ service. The Lync Edge Servers deployed
in the perimeter of the Global Meeting Exchange™ network (i.e. the “Exchange”) where the
jamvee™ service is hosted control how users outside the Exchange network firewall can
connect to the jamvee™ internal Lync Server deployment and the unified conference bridge
within the Exchange infrastructure.
The following diagram illustrates a typical Lync federated deployment with the jamvee™
service over the public internet:
Figure 1: Microsoft® Lync™ federation with jamvee.com
The jamvee™ Exchange Lync Edge Servers are deployed with an “Open Lync Federation”
model so they can be auto-discovered. In most cases, if “Open Lync Federation” is also
configured on the enterprise Lync Edge Server, federated access should automatically occur
when a user creates their first session to jamvee.com. If that fails, then the instructions in this
document detail how to configure your systems to federate with jamvee.com.

Access Methods
It is possible to federate your Lync estate with the jamvee™ service, using a both dedicated
and public access methods. More detail on each access method is provided in the jamvee™
Customer Systems Administrator Guide, available from https://enterprise.jamvee.com/documentation.
The following sections describe 3 ways of connecting a Lync estate to the jamvee™ Exchange
network on which jamvee™ Unified Communications (UC) resides.
2.1
Public Internet
Jamvee™ supports a federated connection from an enterprise, or Lync 365 deployment, via the
Public Internet. This connection is also known as a Exchange Federated Access Trunk. A
Microsoft Lync Federation connection is the standard mechanism supported by Microsoft to
allow the interconnection of different Lync domains.
Access via the Public Internet provides the following benefits:
• Ease of Provisioning – this access method is the easiest way to get endpoints/clients running
Lync bridged into a jamvee™ conference since there are no physical transport links to
provision – however, the quality and performance is limited to “best effort” since it relies on
Public Internet connections and the quality for real-time communications of an Internet
connection can vary widely depending on many different network conditions including overall
latency and packet loss.
• Lowest Cost – this option is the lowest cost access method
This transport access method is ideal for those organizations who require federated Microsoft
Lync access to jamvee™ Unified Conferencing service, and accept the quality and reliability of
this access method, albeit poorer than direct connection access.
2.2
IP Transit Access with QoS (i.e. Public Internet access with QoS)
A global IP network backbone (IP Transit) is available that can be used to access the jamvee™
service using QoS tagging of jamvee™ data across the IP Transit network between the
customer’s local-loop access port on the nearest IP Transit router and the core Exchange
network where the jamvee™ service is hosted. This offers a higher-level of service for
transmitting real-time jamvee™ media form the customer premise to the jamvee™ service. The
customer local loop, i.e. the link from the customer perimeter Internet router to the nearest IP
Transit PoP) must be dedicated to jamvee™ access in order to maintain the higher quality
service.

This Access Method provides the following benefits:
• Broad Reach – a global Internet (IP) transport network with QoS capabilities
• Destination QoS – ability to provide a higher quality level of IP packet transport over Tata
Communications’ global IP backbone, resulting in a better overall quality of experience for a
unified conference call with real-time media traffic (video and voice) when compared to the
variability of standard Public Internet access.
• Standard Internet Addressing – utilizes standard Internet addressing for simplified
management and control
• Lower Cost – the IP Transit connection is a great intermediate solution as it is lower cost than
a full private MPLS connection and but significantly higher quality than a best effort, variable
Public Internet connection.
This access method will be of interest to enterprises who require a dedicated Internet transport
with QoS, but do not need the full capabilities of private MPLS access. This service offers better
quality that that delivered by other unified conferencing providers who have to rely solely on the
public Internet.
TCP/UDP Port configuration needed for federated Microsoft Lync
connections
Once you have provisioned and integrated the Lync Edge Server with the internal Lync
deployment, all the necessary firewall/proxy server settings are part of that architecture.
Provisioning and setting the federation architecture within the enterprise perimeter network
(DMZ) is the responsibility of the customer.
There is nothing additional that is required for federated Lync access to jamvee, other than
provisioning the Lync Edge Server to federate with the jamvee™ Unified Communications
service (if required).

Federation Checklist
 Enable Lync on your account
 Federate with the jamvee™ service…
If your Lync deployment is not configured as “Open Federation,”
you will need to add lyncfed.jamvee.com among your list of federated partners.
Note: for details about the different methods you can use to start the Lync Server
Control Panel, see Open Lync Server Administrative Tools.
 You must ensure that you have a publicly-issued certificate installed on your Edge
server.
 Ensure the enterprise firewall allows the following ports to/from the jamvee™ service:




New York: 64.86.68.0/23

Note: If possible these IP addresses should not appear in a NAT – as this can lead to
no audio, no video or one way communication
 Make sure to update the DNS SRV record for your Lync™ domain.
Note: Your edge server should resolve the jamvee™ lyncfed URL, by making a query
to the Public DNS service.

to the enterprise Edge Server to attempt to minimize latency between the end-user client and
the jamvee™ unified conference bridge.
