  • Hi,

    Please refer to this article:https://docs.microsoft.com/en-us/lyncserver/lync-server-2013-topologies-for-ip-phones

    In my understanding, Lync Phone Edition requires a number of DHCP options to allow the phones to “find their way home” to the pool and sign in.

    The Options required are:

    • Option 42: NTP Server
    • Option 43: Certificate Service Provisioning URL
    • Option 120: SIP Server

    If your device is external,  make sure these options point to the correct services.
