  • Hi MS follower,

    For Lync peer to peer call, as the name suggests, media will flow directly between each end point and signaling via the Front End.

    For PSTN conference call, it is like following

    Lync Client --> Front End --> Mediation --> PSTN Gateway --> External

    Here is a document about Lync Traffic Flow Diagrams, it’s same to SFB server 2015, please refer to

  • Thank you Alice.

    I find it hard to understand the flow diagrams. Is there a reference article that could just explain the work flow in laymen terminology

    Hi MS Follower,

    Session Initiation Protocol (SIP) is used to initiate and manage Voice over IP (VoIP) communications sessions for basic telephone service and for additional real-time communication services, such as instant messaging, conferencing, presence detection, and multimedia, it's a logic concept.

    Based on my research, you can refer to the document below, I think it will be helpful

  • thnx.

    Do you think it would be fair to say-Trunks/sip-trunks are just Numbers that are grouped in a specific region or country and each group will have its associated gateway?

    Some scenarios that needs answers:-

    User-1 is based in UK (+44 1234 333 xx) and User2 is based in United states (+1 xxxx xxxx xxx)

    Scenario 1:- User 1 & 2 have a P2P audio and video call. Based on the work flow provided in the document , how will you consider it in a flow chart? This will be defined as a local lync call internally right!

    Scenario 2:- User1 connect from home and User2 is at Office network. What will be the  work flow in this case?
