    Have I understood correctly, but in my mind in the version v.6.8
    1.) [A/V and Web Conf]
    The traffic from pool to OWAs is marked as one-way, but the arrow must be actually two ways. OWA needs connection back to pool as well.

    2.) [A/V and Web Conf] & [Enterprise voice]
    TCP ports 50000 – 59999 is pointing to the Lync client. But TechNet’s “Port Summary”s says only: ‘Required for federating with partners running OC2007, OC2007R2, L2010 and L2013.’
    So if you have just external client (LWA or Lync Attendee), are these ports required or not, and is the TechNet’s statement wrong?

    3. [Application sharing]
    SRTP traffic have also TCP 50k ports, but TechNet says nothing about that. Application sharing is only mentioned on the internal interface. What is correct?
