  • Yes, it is possible to use a HLB to load balance mediation service traffic if you like.  Here:

    http://technet.microsoft.com/en-us/library/gg398833.aspx

    You will find ports 5067 and 5068 (default mediation server ports) along with 5070 (internal server to server traffic port).  I will say in experience that I have found it easier to take advantage of the native load balancing within the product.  Creating two SIP Trunks in the CUCM and having it load balance between the servers and monitor the state of the SIP trunk.

    Enjoy.

  • You can use hardware load balancing to distribute traffic from a Mediation Server pool’s gateway peer, including a PSTN gateway, IP-PBX, or SIP trunk Session Border Control (SBC).

    In addition, please refer to the Hardware Load Balancer Requirements for Lync Server 2010. Hope it is useful.
