The evaluation of voice quality depends on users' tolerance for voice quality, which you should consider.
For users with higher tolerance for voice quality, use the advantage-factor command to configure the
advantage factor. When the system calculates the ICPIF value, it substracts the advantage factor to
modify ICPIF and MOS values, so both objective and subjective factors are considered.
The voice operation requires both the NQA server and the NQA client. Before you perform a voice
operation, configure a UDP listening service on the NQA server. For more information about UDP
listening service configuration, see "
556HConfiguring the NQA server."
A voice operation cannot repeat.
To configure a voice operation:
Ste
p
Command
Remarks
1. Enter system view.
system-view

2. Create an NQA operation
and enter NQA operation
view.
nqa entry admin-name
operation-tag
By default, no NQA operation is
created.
3. Specify the voice type and
enter its view.
type voice N/A
4. Configure the destination
address of voice packets.
destination ip ip-address
By default, no destination IP
address is configured.
The destination IP address must be
the same as that of the listening
service on the NQA server.
5. Configure the destination port
of voice packets.
destination port port-number
By default, no destination port
number is configured.
The destination port must be the
same as that of the listening service
on the NQA server.
6. Specify the codec type.
codec-type { g711a | g711u |
g729a }
Optional.
By default, the codec type is
G.711 A-law.
7. Configure the advantage
factor for calculating MOS
and ICPIF values.
advantage-factor factor
Optional.
By default, the advantage factor is
0.
8. Specify the source IP address
of voice packets.
source ip ip-address
Optional.
By default, no source IP address is
specified.
The source IP address must be the
IP address of a local interface. The
local interface must be up.
Otherwise, no voice packets can
be sent out.
9. Specify the source port
number of voice packets.
source port port-number
Optional.
By default, no source port number
is specified.
