  • If the call is coming from the PSTN through Lync to UM, then no you will have to run that utility after you do the tasks on the UM/Exchange side first.

  • You Need a certified Gateway to connect to the excahnge um Server. For OCS/Lync intergration you have allways to run the OCSumutil to create a sip account for the SA or AA.

  • Chan76,

    I did the same test as you expected. Yes. It's possible. I posted another message for connecting a Auticodes M2000 with Lync 2013 or Exchange 2013 with 'Sip Secured' mode. Behind this test, I didn't tell the secret that Lync was not able to talk to Exchange because of Encryption level.

    So it's hard since you need a Microsoft certificated gateway to talk to ExchangeUM if you like to make sure both of your Lync and UMIPgatewqay work. ExchangeUM requires 'Secured' when it works with Lync 2013.

    What I did is to create a UMdialplan and to make sure my DID can be forwared to Exchange UM.

    This Umdialplan must be Secured unless you want to try Get-CsMediaConfiguration with Encryptionlevel

    It can alter encryption mode between ExchangeUM and Lync. If you modify it as:

    Set-CsMediaConfiguration site:Redmond1 -EncryptionLevel donotsupportencryption

    Your Lync will talk to Exchang in Unsecured mode. Next, you can modify your UMDialPlan as Unscured.

    At last, you are free to implement PSTN gateways with your ExchangeUM.

    HOWEVER, I wouldn't do this way. Your Lync mediation server can help you. My gateway routes the suscriber access number to Lync when it works as 'Sip Secured' mode. I created a normolization plan to translate from 11 digits, 1778xxx xxxx, to +999. I used ocsumutil.exe to create SA and AA with number +999 and +998.

    When I call this access number, it goes to Lync then to Exchange UM.
