  • Question

  • I have a requirement to support 100+ analog devices, does anyone know of a supported gateway that scales within a single active directory domain?

  • We are using 6 Audiocodes MP124 with 24 analog ports, because our analog lines are on different locations on our campus. This GW supports 24 Lines without encryption and 16 lines with encryption.

  • Are there any limitations to how many of these you can deploy to a site?

  • Hm, we use the analog lines only for fax and have not configured the analog lines in Lync. Only limitation may be the bandwidth you are using in your site.

    You have also your Lync limitation, if you are using a Lync SBA, you can deploy up to 1000 Lync User in this site, but I would prefer for more then 300 User a Lync Standard Server

    You will not have problems with 100+ analog lines and more lines.

  •  Could this solution be extended to support 500+ devices is there an alternative to having so many devices i.e. a device that supports more than 24 ports in the one box?

    Is this device supported by Microsoft as I can't see it listed?

  • When configure the analog gateway to use Lync Server, and the gateway must be one of the following:

    • An analog telephone adapter (ATA)
    • A PSTN analog gateway
    • A Survivable Branch Appliance that includes a PSTN analog gateway
    • A Survivable Branch Appliance that includes a PSTN gateway that communicates with an ATA

    This article explains how to configure AudioCodes Enhanced Gateway components for branch office locations. Have a check.

  • i agree, i don't see the mp124 in qualified devices either...hmm

    the Mediant 1000 is in certified list will do 24fxs max as well, but more costly.

  • I would use a traditional PBX with 500+ analog lines and connect it to a Lync enhanced gateway like our Ferrari electronic OfficeMaster Gate which would integrate it fully into Lync.

  • Johan, we're trying to get rid of the pbx!  ;-)

    I guess we are looking for a high density FXS device. I suspect most any SIP fxs gateway will work with Lync, but of course we want certified/qualified.

  • Hi Matt, (as far as I see you are not the one originally asking :-))

    that may be a misunderstanding: I thought of traditional PBX hardware with ISDN trunk to support 500+ FXS ports - this is proven technology which still can be used behind a qualified Lync gateway instead of deploying 20 or more 24 port SIP ATAs. I probably should draw it in Visio :-) And this solution even introduces lower speech latency!

  • I still agree with Johan, if you will use 500+ analog extensions you should use a traditional PBX and not the FXS devices.

    If you will use the msbg 1000 be aware if you use SRTP only 18 analog device could be used because one port is used for encrypt/decrypt.

  • Sorry if I seemed to take thread hostage., not intent. ;-)
    It was a lighthearted, off-hand comment, and somewhat self mocking our/Microsoft/Lync need to get rid of the "pbx".

    But also hitting on our own occasional need to support more than 24 analogue devices, and how to do that without making the Johan noted monster. I'll start a new thread: "How to support 125 analogue devices." I suspect Zideq just might be trying to solve the same challenges (but of course I don't know), so to avoid thread hostage I'll post new thread and would appreciate input of you guys.

    thanks

  • Hi,

    can be done using Audiocodes MP 124 x 6. that has to go behind a Mediant 1000 eSBC to make it as a "Certified" deployment.

  • The MP-124 is not a PSTN gateway.  That is why it is not certified as one.

    We have nearly a dozen.  They work OK with Lync, but can be hard to get configured correctly.  I would only use them with voice, not fax and not data.
