Packet loss can be catered for by means of
transmitting the fax data packets redundantly n
times. This can be configured for both the low-
speed and the high-speed traffic separately. The
default for both parameters is 0 (no redundant
transmission). Note that values >0 provide more
reliable transmission, but consume additional
bandwidth.

period
For proper operation a dejitter buffer is used on
the receiver. The dejitter period can be adjusted
to compensate for the jitter imposed by the
network. The default value is 200ms which
should be ok for almost any transmission
network. Only in exceptional cases it may be
necessary to increase this value (maximum
400ms).
Example: Enable fax relay
The following example shows how to configure fax relay. The max bit rate is increased to 14400
kBit/sec.

32.11 Show VoIP Profile Configuration and assign it to a
VoIP Gateway
To activate a created VoIP profile it must be used by an H.323 or ISoIP gateway. Prior to using the
profile by a gateway it is possible to display the VoIP profiles.
Note:
The default VoIP profile always exists. Settings such as fax/data can be ignored at this time.
Procedure
To show the actual VoIP profiles and use it by a VoIP gateway
