Presence Publish IP Group
ID
[PresencePublishIPGroupId]
Assigns the IP Group (by ID) configured for the Skype for Business
Server (presence server). This is where the device sends SIP
PUBLISH messages to notify of changes in presence status of Skype
for Business 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 316.

PSTN Alert Timeout
configure voip > sip-
definition settings > pstn-
alert-timeout
[PSTNAlertTimeout]
Digital: Defines the Alert Timeout (in seconds) for calls sent to the
PSTN. This timer is used between the time a Setup message is sent to
the Tel side (IP-to-Tel call establishment) and a Connect message is
received. If an Alerting message is received, the timer is restarted. If
the timer expires before the call is answered, the device disconnects
the call and sends a SIP 408 request timeout response to the SIP party
that initiated the call.
Analog: Defines the Alert Timeout (in seconds) for calls to the Tel side.
This timer is used between the time a ring is generated (FXS) or a line
is seized (FXO), until the call is connected. For example: If the FXS
device receives an INVITE, it generates a ring to the phone and sends
a SIP 180 Ringing response to the IP. If the phone is not answered
within the time interval set by the parameter, the device cancels the
call by sending a SIP 408 response.
The valid value range is 1 to 600 (in seconds). The default is 180.
Note: If per trunk configuration (using TrunkPSTNAlertTimeout) is set
to other than default, the PSTNAlertTimeout parameter value is
overridden..
RTP Only Mode
configure voip > sip-
definition settings > rtp-only-
mode
[RTPOnlyMode]
Enables the device to send and receive RTP packets to and from
remote endpoints without the need to establish a SIP session. The
remote IP address is determined according to the Tel-to-IP Routing
table (Prefix parameter). The port is the same port as the local RTP
port (configured by the BaseUDPPort parameter and the channel on
which the call is received).
