  • I am glad to hear that you are looking at replacing your Cisco PBX with Lync!  So you will not be able to just keep using your Cisco phones with Lync natively.  There are third party products that will allow you to so that you can keep you investment in your handsets.  Although I will say that would will get a much better experience using native Lync endpoints.

    Third-party solutions:

  • If you really want to keep your Cisco phones, there might be a workaround but you will not have the same features on the phones as you would have with Lync-compatible phones. I still would recommend getting new phones but this is a place where you can start:

    Cisco offers SIP firmwares for it's phones. You can reflash the phones with this firmware and then register them on Lync using by example a gateway device like AudioCodes. I have to say that reflashing the firmware will require a TFTP server and is not a very easy procedure.

    You would have to configure them on Lync using the pshell command New-CsAnalogDevice
