Is the following possible - Lync and Mitel MCD RRS feed

  • Question

  • Hi,

    I am playing with Lync and it is looking excellent.  I am looking to find out if the following is possible, I don't need the actual details on how to do it just some rough info...

    1. Setup a dial in number for Lync conferences where the number is handled our Mitel MCD and passed to Lync?  E.g. I define 8000 on the MCD to be the conference number and when I call it the call ends up at Lync.
    2. Control deskphone using Lync client.  E.g. if I select dial I want it to make my deskphone dial the person in question.  I believe this could be done in OCS using a Mitel Border Gateway server

  • I'm not sure about point 1 as I've yet to try getting Mitel to Lync working. In order to control a mitel desk phone you'd need a CTI server, in this case Mitels Live business Gateway but I don't think it has been confirmed as working with Lync yet, but it might work.

    1. To get this working you'll need to have a connection between the Mitel and Lync. this can be either a direct SIP connection or through a gateway. Then you'll need to configure the Mitel to forward calls for your conference number to the Lync Mediation server. You'll need to make sure on Lync side that it knows how to translate the incoming number format to E.164 format (+123456789), which matches the Lync conference number.  To do this integration, I would recommend contacting your telephony partner that installed the Mitel PBX.
      As for now, there is no documentation released from Microsoft which PBX and software versions for PBX'es are supported for Direct SIP
    2. You are talking about Remote Call Control. Lync supports this feature but just as in step 1, little to nothing is known at this point which PBX'es and software versions are supported. Lync was just released few weeks ago and they are working hard on it. The best you can do now is contact your Mitel partner and see if they have information available how to do it and if it is supported.

  • We managed to setup Mitel with LBG, where LBG "talks" TCP to the Lync pool. Commands used are:

    1)     New-CsTrustedApplicationpool -Identity <FQDN LBG> -Registrar <FQDN Lync> –Site 1 –TreatAsAuthenticated $True –ThrottleAsServer $True –RequiresReplication $False

    2)     New-CsTrustedApplication -ApplicationID RCC -TrustedApplicationPoolFqdn <FQDN LBG> -Port 5060 –EnableTcp

    3)     Enable-CsTopology

    4)     Set-CsRegistrar registrar:<FQDN Lync> -SipServerTcpPort 5060

    5)     $tcpRoute = New-CsStaticRoute -TCPRoute -Destination <IP adres LBG> -Port 5060 -MatchUri <Remote CC URI on ICP tab LBG>

    6)     Set-CsStaticRoutingConfiguration -Route @{Add=$tcpRoute}

    7)     Enable-CsTopology

    8)     Get-CsTopology -AsXml | Out-File C:\rcc.xml (change IP adress on section Cluster Fqdn="<FQDN LBG>" from to IP adress of LBG!!)

    9)     Publish-CsTopology –FileName C:\rcc.xml

    With this the Mitel/LBG is nicely connected to Lync.

  • How much functionality did this give you?  Does it enable RCC?  I am looking to implement LBG with Lync so I am also interested in how much configuration LBG required too?

  • that sounds interesting - can you confirm that all the functionality is there re RCC/enterprise voice?? Can you also confirm the version of LBG that you used?


    We are looking to upgrade to Lync 2010 as soon as possible but are being held up by Mitel being slow to release an updated version of LBG......

  • Have not looked into this forum for a while, so to both TRO_IT / Samlw:

    This delivered RCC indeed, with similar functionality delivered as in OCS 2007 R2. LBG configuration is the same as done with OCS, the only thing different is the setup in powershell for Lync. Enterprise voice is also setup in some fashion but is not related to RCC, especially since dual forking has been withdrawn with Lync. As for the LBG version, take the lastes from the MOL download section (I used

  • I have also been running into problems getting LBG and Lync talking.  SpongeVoIP, I plan to try your solution,  however if I run into problems do you ever do remote consulting on the side.   Please reply here or email me at dk619@prodigy.net.
