    Anyone familiar with any issues with this setup?

    We're having intermittent success with these phones successfully
    completing the dhcp process. The router shows the addresses as bound
    but, the phone never reboots/initializes with the address and the
    address is unpingable.

    Also seeing conflicts immediately after pool clearing or router reboot

    Alternatively, all works well after some router reboots.

    IOS bug/setting?
    Polycom bug/setting?
