    Question

  • Hi ,

    Got a question regarding a/v pools and would be grateful of some advise.

    If I have an a/v pool in America and another in Spain connected via a WAN. A local dialin number is provided for Spanish users and a local number for American users. If an American user is hosting the meeting and the Spanish guy dials his local dialin number to join the conference what is happening in the background to set this up for example:

    1.       Does the Spanish user connect to his local a/v pool in Spain and if so how does that link to his American colleagues a/v pool  or does Lync look at the conference ID determine that meeting is hosted in America and send the user to the American a/v pool/  Basically how is the meeting setup in the background

     

    2.       What if the Spainish a/v pool goes down. Will the user dialing the Spanish local dialin number be able to use pool in America.  If  a Spanish user hosts a meeting will all meeting fail due to the pool being down.

     

    A bit confused here and cant find any detailed documentation on the web.

     

    Thanks for reading

    The Conference will be hosted on the A/V Pool where the User is homed. So if the american user create the conference the spanish user dialin in spain and will be directed to the conference in america.

     

    2.       What if the Spainish a/v pool goes down. Will the user dialing the Spanish local dialin number be able to use pool in America.  If  a Spanish user hosts a meeting will all meeting fail due to the pool being down.

       You can add the spanish number also to the pool in america for fail over. If the pool in spain is not accessible no hoste meeting of this pool is accessible.

  • Hi Holger,

     

    Thanks for the quick response that helps my understanding. Can you help answer the call flow in the scenario I described. So when the Spanish guy dials his local dialin number the following will be happening in the background:

     

    1. Dials local Spanish dialin number

    2. Gets connected to Spanish Front end pool and hears "Welcome to the conference suite" played from conference auto attendant (CAA) in Spain.

    3. Conference Id is looked up via the Focus factory which determines that the conference is hosted by a user in America and sends the call over the WAN to the American A\ V pool

    Is this correct?

    If this is right does this mean that the Front end pool (registar) in Spain has to be UP for step 1 to be a sucess as if it is down the CAA will not play the welcome message.

     

    Thanks

  • I depend on the configuration of your PSTN Gateway. If you have a co-located A/V and the mediation server is not reachable yes.

    But you can configure the american number also for spain and forward the number in spain for failover to america.

  • What if the A\V pool  of the user hosting the meeting is down (internal conf). Will Lync automatically use an a\v pool in another region?

     

    Thanks again.
