Note:

The device can only detect a broken RTP connection if silence
compression is disabled for the RTP session.

If during a call the source IP address (from where the RTP
packets are received by the device) is changed without
notifying the device, the device rejects these RTP packets. To
overcome this, configure the DisconnectOnBrokenConnection
parameter to 0. By this configuration, the device doesn't detect
RTP packets arriving from the original source IP address and
switches (after 300 msec) to the RTP packets arriving from the
new source IP address.

The corresponding global parameter is
DisconnectOnBrokenConnection.
Defines the pulse-code modulation (PCM) input gain control (in
decibels). This defines the level of the received signal for Tel-to-
IP calls.
The valid range is -32 to 31 dB. The default is 0 dB.
Note: The corresponding global parameter is InputGain.
Defines the voice gain control (in decibels). This defines the level
of the transmitted signal for IP-to-Tel calls.
The valid range is -32 to 31 dB. The default is 0 dB.
Note: The corresponding global parameter is VoiceVolume.
Defines the preferred RTP media IP addressing version for
outgoing SIP calls. This is indicated in the "c=" field (Connection
Information) of the SDP.

[0] Only IPv4 = (Default) SDP offer includes only IPv4 media
IP addresses.

[1] Only IPv6 = SDP offer includes only IPv6 media IP
addresses.

[2] Prefer IPv4 = SDP offer includes IPv4 and IPv6 media IP
addresses, but the first media is IPv4.

[3] Prefer IPv6 = SDP offer includes IPv4 and IPv6 media IP
addresses, but the first media is IPv6.
Notes:

This parameter is applicable only when the device offers an
SDP.

The IP addressing version is determined according to the first
SDP "m=" field.

The corresponding global parameter is
MediaIPVersionPreference.
Enables symmetric MKI negotiation.

[0] Disable = (Default) The device includes the MKI in its SIP
200 OK response according to the SRTPTxPacketMKISize
parameter (if set to 0, it is not included; if set to any other
value, it is included with this value).

[1] Enable = The answer crypto line contains (or excludes) an
MKI value according to the selected crypto line in the offer. For
example, assume that the device receives an INVITE
containing the following two crypto lines in SDP:
a=crypto:2 AES_CM_128_HMAC_SHA1_80
