users when making and receiving calls using third-party endpoint devices.
For more information on integration with Microsoft presence, see
Microsoft Skype for Business Presence of Third-Party Endpoints on page

Defines the index of the first ringback tone in the CPT file. This option
enables an Application server to request the device to play a distinctive
ringback tone to the calling party according to the destination of the call.
The tone is played according to the Alert-Info header received in the 180
Ringing SIP response (the value of the Alert-Info header is added to the
value of the parameter).
The valid range is -1 to 1,000. The default is -1 (i.e., play standard
ringback tone).
Note:

It is assumed that all ringback tones are defined in sequence in the
CPT file.

In case of an MLPP call, the device uses the value of the parameter
plus 1 as the index of the ringback tone in the CPT file (e.g., if this
value is set to 1, then the index is 2, i.e., 1 + 1).
Global parameter that defines the preferred RTP media IP addressing
version (IPv4 or IPv6) for outgoing SIP calls. You can also configure this
functionality per specific calls, using IP Profiles
(IpProfile_MediaIPVersionPreference). For a detailed description of the
parameter and for configuring this functionality in the IP Profiles table, see
Configuring IP Profiles on page 418.
Defines how often (in seconds) the device sends ping messages (keep
alive) to check whether the WebSocket session with the Web client is still
connected.
The valid value is 5 to 2000000. The default is 0 (i.e., ping messages are
not sent).
For more information on WebSocket, see SIP over WebSocket on page
568.
Note: The device always replies to WebSocket ping control messages
with pong messages.
Defines the time interval (in msec) between the first transmission of a SIP
