Parameter Description
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.

to other than default, the PSTNAlertTimeout parameter value is
overridden.

[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).
 [0] Disable (default)
 [1] Transmit & Receive = Send and receive RTP packets.
 [2] Transmit Only= Send RTP packets only.
 [3] Receive Only= Receive RTP packets only.
Note:
 To activate the RTP Only feature without using ISDN / CAS
signaling, you must do the following:

Configure E1/T1 Transparent protocol type (set the
ProtocoType parameter to 5 or 6).

Enable the TDM-over-IP feature (set the EnableTDMoverIP
parameter to 1).
 To configure the RTP Only mode per trunk, use the
RTPOnlyModeForTrunk_x parameter.
 If per trunk configuration (using the RTPOnlyModeForTrunk_ID
parameter) is set to a value other than the default, the
RTPOnlyMode parameter value is ignored.
[RTPOnlyModeForTrunk_x] Enables the RTP Only feature per trunk. The x in the parameter name
denotes the trunk number, where 0 is Trunk 1. For a description of the
parameter, see the RTPOnlyMode parameter.
