SBA deployment and testing with Lync 2013 Part II

In Part 1 of this article we walked through the steps to deploy a Lync 2013 SBA in a simulated branch office environment. Here in Part II, we will perform some tests of the SBA to verify the correct functional behavior using Microsoft-certified IP deskphones such as the Polycom CX600 LPE and the Polycom VVX310/410 Business Media phones. We also collect some performance results of the failover and failback times in this lab. The diagram for this lab environment consists of a Lync 2013 SE FE server in the "Main Site" and an Audiocodes M800 SBA in the "Branch Site". In the main site we have a Lync 2013 PC Client and a Polycom VVX410 phone and both accounts used to login are homed on the Lync SE FE server. At the branch site we have a Polycom CX600 phone and a Polycom VVX310 phone and both account used to login are homed on the SBA. Below is the diagram of this setup:

The following tests will be performed in the sequence below:
Test #1: WAN Link Up: 
    1a. Login to all phones using PIN Auth
    1b. Login to all phones using NTLM Auth
    1c. P2P voice calls between Main site and Branch Site
    1d. Multiparty voice calls between Main site and Branch Site

Test #2: WAN Link Down
     2a. Phone registration status after WAN Link is down and failover time
     2b. Initiate P2P calls within Branch site
     2c. Phone registration status after WAN Link is restored and failback time


Test #3: WAN Link Down during active calls
     3a. Initiate P2P voice call within Branch site, then WAN Link fails
     3b. Initiate multiparty voice call between Main site and Branch site, then WAN Link fails
