Parameter Description
then CNG occurs.
Note: The parameter is applicable only to the Gateway application.
[SDPEcanFormat]
Defines the echo canceller format in the outgoing SDP. The 'ecan'
attribute is used in the SDP to indicate the use of echo cancellation.
 [0] = (Default) The 'ecan' attribute appears on the 'a=gpmd' line.
 [1] = The 'ecan' attribute appears as a separate attribute.
 [2] = The 'ecan' attribute is not included in the SDP.
 [3] = The 'ecan' attribute and the 'vbd' parameter are not included in
the SDP.
Note: The parameter is applicable only when the IsFaxUsed parameter
is set to 2, and for re-INVITE messages generated by the device as
result of modem or fax tone detection.
First Call Ringback Tone
ID
[FirstCallRBTId]
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).
Notes:
 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).
Reanswer Time
[RegretTime]
Defines the time period the device waits for an MFC R2 Resume
(Reanswer) signal once a Suspend (Clear back) signal is received from
the PBX. If this timer expires, the call is released. Note that this is
applicable only to the MFC-R2 CAS Brazil variant.
The valid range is 0 to 255 (in seconds). The default is 0.
PSTN Alert Timeout
[PSTNAlertTimeout]
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.
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
[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.
