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
inline:TAaxNnQt8/qLQMnDuG4vxYfWl6K7eBK/uf
k04pR4|2^31|1:1
a=crypto:3 AES_CM_128_HMAC_SHA1_80
