
[1] PI =1, [8] PI =8: For IP-to-Tel calls, if the parameter
EnableEarlyMedia is set to 1, the device sends 180 Ringing with
SDP in response to an ISDN Alerting or it sends a 183 Session
Progress message with SDP in response to only the first received
ISDN Proceeding or Progress message after a call is placed to
PBX/PSTN over the trunk.
Note: This parameter can also be configured per IP Profile (using the
IPProfile parameter) and Tel Profile (using the TelProfile parameter).
Enables the device to send a Re-INVITE with a new (different) SRTP
key (in the SDP) upon receipt of a SIP 181 response ("call is being
forwarded").

[0] = Disable (default)

[1] = Enable
Note: This parameter is applicable only if SRTP is used.
Defines the maximum number of active SIP dialogs that are not call
related (i.e., REGISTER and SUBSCRIBE). This parameter is used to
control the Registration/Subscription rate.
The valid range is 1 to 20. The default value is 20.

[0] = Only use coders from the coder list (default).

[1] = Use Transparent coder for data calls (according to RFC
4040).
The Transparent' coder can be used on data calls. When the device
receives a Setup message from the ISDN with 'TransferCapabilities =
data', it can initiate a call using the coder 'Transparent' (even if the
coder is not included in the coder list).
The initiated INVITE includes the following SDP attribute:
a=rtpmap:97 CLEARMODE/8000
The default payload type is set according to the CodersGroup
parameter. If the Transparent coder is not defined, the default value is
set to 56. The payload type is negotiated with the remote side, i.e.,
the selected payload type is according to the remote side selection.
The receiving device must include the 'Transparent' coder in its coder
list.
Enables the IP-to-IP Call Routing application.

[0] Disable (default)

[1] Enable
Note: For this parameter to take effect, a device reset is required.
Defines the voice transcoding mode (media negotiation) between two
user agents for the IP-to-IP application.

[0] Only if Required = Do not force transcoding. Many of the media
settings (such as gain control) are not implemented on the voice
stream. The device passes packets RTP to RTP packets without
any processing.

[1] Force = Force transcoding on the outgoing IP leg. The device
interworks the media by implementing DSP transcoding. (default)
Enables transcoding of calls according to RFC 4117.

[0] Disable (default)

[1] Enable
