Dial In Conferencing - Multiple Pools RRS feed

  • Question

  • Hi,

    I have a question from a potential customer regarding dial-in conferencing.

    There are two pools, one in india, and another in the UK. A conference is scheduled by a user on the UK pool, 10 people dial in to the UK conferencing number and another 5 dial into the India number.

    Are there 5 separate voice connections maintained between India and the UK, or does the pool in india only have a single connection to the UK and it simply sends across one audio stream along with the associated data to let the UK pool know who is speaking at that time.

    Obviously my customers concern is the amount of bandwidth that will be used between the two sites

    Is there a quick and easy answer to this question, or even better any documentation that might help explain?

  • There will be 5 calls coming into the mediation server and hitting the India front end server. The india front end server will redirect these requests to the correct conference hosted in the UK. However all 5 calls will still be active from the mediation server going to that conferencing MCU on the UK Front end.

    Therefore, there should be 5 active connections going over the WAN to UK from India.

  • With the same scenario, multiple pools and dial-in conferencing, is it possible to have a single dial-in conferencing 800 number that can be serviced by both pools? (based on user pool homing)  I would presume, based on what is above, that this would work since conferencing numbers are stored at the forest level.  It is not something I have tried yet and am curious if anyone else has.

    Each pool would have a mediation server.  The telco provider (SIP provider in this case) can send calls to the single 800 number to a specific session border controller (based on SIP provider routing) to one of the mediation servers. 

    Thanks!

  • Hi Matt,

    We have four pools and the one 1800 number services all four pools. We have the 1800 number come in on one pool and it connects users to the appropriate pool for conferences. The conference ID is the key to finding the right conference resource not the inbound DID. So in our case some one can look up a local number in their respective region and just dialin on a local number rather than a 1800 number and it doesnt matter which one they use they will always get to the right pool and conference based on the conference ID.

    Cheers

  • Great info, thanks for sharing. 

    Out of curiousity do you have all the conferencing numbers listed under one region, or do you have a number of regions configured so the user selects?  Do you also have the 800 number show up for all regions?

    Thanks in advance!

  • Hi Matt,

    We have the same 1800 number show in every region with their local access number. We only have the local access number appear in the applicable region. So we have four regions with a toll free and one local access in each. The toll free is linked to our main region local access number which has the highest available number of PSTN trunks to avoid inbound call blockage. There is nothing stopping us having multiple 1800 numbers to help spread the load across each region but at the moment our volumes doesnt call for it yet.

    Cheers
    Chris
