FXO Gateway for minimal lab system - Linksys SPA-3102? RRS feed

  • Question

  • I would like to set up a minimal/portable test/demo system, with one POTS line.

    I would appreciate feedback on experience with small/low cost gateway devices.

    One candidate seems to be Lynksys SPA-3102, for which I have found configuration info for another software PBX product.

    The Grandstream HT-503 also looks attractive, pocket-sized device.

    These devices have one FXO and one FXS (plus Ethernet)

    I don't expect to find this type of device on an official/tested compatibility list, but I imagine someone else has been experimenting...

  • CBS3,


    Audio Codes makes a MediaPack device that can include 2 FXS, 2 FXO and an ethernet port.  These devices are typically what are used at the ignite training and I have used them with Lync and OCS.


    Hope this helps!

  • I can only recommend you using supported devices from the compatibility lists, otherwise you'll run into trouble especially with Lync since it is just released.

    I don't think you'll find a lot of folks here that are using unsupported gateways.

  • An update...

    Finding no positive feedback on anything but the AudioCodes gear, I contacted AudioCodes.  They were helpful in the presales mode.  They confirmed that the MediaPack family, while not submitted for certification, uses the same core software as the Mediant family that is certified.  They also confirmed MediaPack products were successfully installed with Lync server.

    I found a MP-114 2FXS/2FXO for $320 and ordered.

    I'm well into the somewhat painful process of initiation with modern telephony gear, to the point the gateway is dialing something, just not the digits I expect.  The resolution to that lies somewhere in normailization rules or dialed number modification tables (I think).

    One note about AudioCodes... not to be taken as a criticism, but factored into an overall approach.  They offer no free support.  You must register the product before you can see firmware updates on their website (documentation, pretty good, is available to the public.)

    Once I got to the point of initiating a Lync call and the gateway responding, I contacted AudioCodes for potential assistance with the gateway config.  They politely explained their support policy; nothing for free, minumum $550.  That is not in the budget for this project.  I may eventually burn a PSS incident and see if they will walk through the gateway setup.

  • CBS3,


    On the audio codes there is a "Message Log" page, I believe it is under the diagnostic tab.  This page shows the exact information being sent to the gateway and what it is doing with it.  Please open that page, make a test call and then copy and paste your ouput into a post.  Once it's here we can take a look at it and see what the issue might be.


    Hope this helps!

  • Yes!

    I was getting ready to open a new thread with topic related to the dialing problem, and post the gateway log as you suggested...  but looking at the gateway's log, iteresting reading ;-) was enough of a hint.  The normalized number received by the gateway wasn't what I expected.  I was confused since I had only one Dial Plan and only one Normalization rule, and it tested successfully within the Lync Control Panel.

    It had to do with a second Lync management console being open in another RDP session to the Lync server.

    I think I will open a new thread for potential benefit of others...


    Thanks for your original suggestion and help

  • For a purpose of POC, I successfully tested GrandStream HT503 Analog Telephone Adapter for use as Analog Phone Gateway in my Lync lab environment. You can see sample configuration here: http://www.lynclog.com/2011/04/grandstream-ata-with-lync-2010.html
