User's Manual
'c=0.0.0.0'.

[5] Not Supported = Used when remote side cannot identify a
call-hold message. The device terminates the received call-hold
message (re-INVITE / UPDATE) and sends a 200 OK to the
initiator of the call hold. The device plays a held tone to the held
party if the 'SBC Play Held Tone' parameter is set to Yes.
Enables the device to handle an incoming INVITE with the
Replaces header for this SIP entity (which does not support this
header). The Replaces header is used to replace an existing SIP
dialog with a new dialog such as in call transfer or call pickup

[0] Transparent = (Default) SIP entity supports the Replaces
header. The device forwards the received INVITE with the
Replaces header as is to the SIP entity.

[1] Handle Locally = The SIP entity does not support INVITE
with the Replaces header. The device terminates the received
INVITE with the Replaces header and establishes a new call
between the SIP entity and the new call party. It then
disconnects the call with the initial call party, by sending it a SIP
BYE request.
For example, assume that the device establishes a call between A
and B. If B initiates a call transfer to C, the device receives an
INVITE with the Replaces header from C. If A supports the
Replaces header, the device simply forwards the INVITE as is to A;
a new call is established between A and C and the call between A
and B is disconnected. However, if A does not support the
Replaces header, the device uses this feature to terminate the
INVITE with Replaces header and handles the transfer for A. The
device does this by connecting A to C, and disconnecting the call
between A and B, by sending a SIP BYE request to B. Note that if
media transcoding is required, the device sends an INVITE to C on
behalf of A with a new SDP offer.
Defines the packetization time (ptime) of the coder in RTP packets
for this SIP entity. This is useful when implementing transrating.

[0] Remote Answer (Default) = Use ptime according to SDP
answer.

[1] Original Offer = Use ptime according to SDP offer.

[2] Preferred Value= Use preferred ptime for negotiation, if
configured by the 'Preferred Ptime' parameter.
Defines the packetization time (in msec) for this SIP entity if the
'SBC SDP Ptime Answer' parameter is set to Preferred Value.
The valid range is 0 to 200. The default is 0 (i.e., preferred ptime is
not used).
Defines silence suppression support for this SIP entity.

[0] Transparent (default) = Forward as is.

[1] Add = Enable silence suppression for each relevant coder
listed in the SDP.

[2] Remove = Disable silence suppression for each relevant
coder listed in the SDP.
