VoipQualityCheck=<type minsamples limit recovertime>
type
Enter one of the following:
ASR1
,
ASR2
,
RoundTripDelay
,
Jitter
or
FractionLost
When type is
ASR1
or
ASR2
:
minsamples
Minimum number of calls for which ASR shall be calculated with:
limit
A value between 0 and 100
recovertime
Seconds to block the profile.
When type is
RoundTripDelay
:
minsamples
Minimum number of seconds RTD must be above:
limit
The highest acceptable value for RTD (in milliseconds)
recovertime
Seconds to block the profile.
When type is
Jitter
:
minsamples
Minimum number of seconds jitter must be above:
limit
The highest acceptable value for jitter (in milliseconds)
recovertime
Seconds to block the profile.
When type is
FractionLost
:
minsamples
Minimum number of seconds FL must be above:
limit
The highest acceptable value for FL (percentage between o and
100)
recovertime
Seconds to block the profile
NOTE: If you base
VoipQualityCheck
on the ASR values: During setup, calls are calculated as
not connected, which lowers the number of connected calls.
Example: If
minsamples
is set at 20, with a
limit
of 80%, 4 calls in the setup phase will
lower the ASR of the previous 20 calls to 80% and the profile will be blocked.
VoipResetVocoderOnReinvite=<yes/no>
Enter yes to create an audible delay in a voice call. Default no.
VoipRtcpTos=<num>
Enter a value between 0 and 255 to set the TOS (type of service) field in the RTCP packet
IP header. Possible values are described in Table 11.7. If your IP network uses diferentiat-
ed services, you can also define the DSCP (differentiated services codepoint) for the RTCP
packets. The DSCP is the first six bits in the TOS octet.
NOTE:
VoipUseIpStack
must be 0 (default).
VoipRtpTos=<num>
Enter a value between 0 and 255 to set the TOS (type of service) field in the RTP packet
IP header. Possible values are described in Table 11.7. If your IP network uses differ-
entiated services, you can also define the DSCP (differentiated services codepoint) for
the RTP packets. The DSCP is the first six bits in the TOS octet.
NOTE:
VoipUseIpStack
must be 0 (default).
VoipSilenceSuppression=<mode>
Activates silence suppression (see Table 4.21).
VoipSuppressCNG=<mode>
Enter On to suppress comfort noise generation. Default is Off. Requires VoipSilence-
Suppression=On.
