 /*
   There are a number of factors that determine PhoneAvailabilityType::PhoneAvailability. The supported states for this enum are:
   { eUnknown, eAvailable, eUnAvailable, eNotAllowed }. eUnknown is the default value, which is set when there is no information
   available that would otherwise determine the availability value. The factors that can influence PhoneAvailability are:
   phone mode, and for a given device (described by DeviceInfo) the model, and the name of the device. For phone control mode, the
   device registration and whether CUCM says the device is CTI controllable (or not) is a factor.
   For Phone Control mode the state machine is:
      is blacklisted model name? -> Yes -> NOT_ALLOWED
         (see Note1 below)
               ||
               \/
               No
               ||
               \/
        is CTI Controllable?
      (determined from CUCM) -> No -> NOT_ALLOWED
               ||
               \/
               Yes
               ||
               \/
   Can we tell if it's registered? -> No -> ?????? TODO: Seems to depends on other factors (look at suggestedAvailability parameter
               ||                                        in DeviceSubProviderImpl.addOrUpdateDevice() in CSF1G Java code.
               \/
               Yes
               ||
               \/
          is Registered?
      (determined from CUCM) -> No -> NOT_AVAILABLE
               ||
               \/
               Yes
               ||
               \/
            AVAILABLE
   ========
   For Softphone mode the state machine is:
         is device excluded?
    (based on "ExcludedDevices"   -> Yes -> NOT_ALLOWED
          config settings
         (see Note2 below))
               ||
               \/
               No
               ||
               \/
           isSoftphone?
      Note1: model name has to match completely, ie it's not a sub-string match, but we are ignoring case. So, if the blacklist
             contains a string "Cisco Unified Personal Communicator" then the model has to match this completely (but can be a
             different case) to be a match. In CSF1G the blacklist is hard-wired to:
                 { "Cisco Unified Personal Communicator",
                   "Cisco Unified Client Services Framework",
                   "Client Services Framework",
                   "Client Services Core" }
      Note2: The "ExcludedDevices" is a comma-separated list of device name prefixes (not model name). Unlike the above, this is
             a sub-string match, but only a "starts with" sub-string match, not anywhere in the string. If the device name
             is a complete match then this is also excluded, ie doesn't have to be a sub-string. For example, if the
             ExcludeDevices list contains { "ECP", "UPC" } then assuming we're in softphone mode, then any device whose
             name starts with the strings ECP or UPC, or whose complete name is either of these will be deemed to be excluded
             and will be marked as NOT_ALLOWED straightaway. In Phone Control mode the "ExcludedDevices" list i not taken into
             account at all in the determination of availability.
      Note3: isSoftphone() function
   The config service provides a list of "blacklisted" device name prefixes, that is, if the name of the device starts with a
   sub-string that matches an entry in the blacklist, then it is straightaway removed from the list? marked as NOT_ALLOWED.
