A selection can be made which items will be anonymized :
When the IP addresses are anonymized ( Anonymize IP addresses checked) then the following mapping is used :
● Every private IP address (10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16) is converted to a 10.x.x.x IP address, e.g.
the first private IP address detected is replaced with 10.0.0.1, the second IP address with 10.0.0.2, etc...
● Every public IP address is converted to a 192.168.x.x IP address, e.g.
the first public IP address detected is replaced with 192.168.0.1, the second IP address with 192.168.0.2, etc...
Important remark: multicast IP addresses (ranging from 188.8.131.52 to 184.108.40.206) are not converted as these IP addresses do no reveal any privacy information.
● Inside a SIP URI the domain name is converted to a 172.16.x.x IP address, e.g.
the first domain name detected is replaced with 172.16.0.1, the second domain name with 172.16.0.2, etc...
After anonymizing all original IP addresses are changed to either a 10.x.x.x IP address (coming from a private IP address ) or
So the anonymized output still gives an indication what the original IP address was without revealing any details.
Digest Authentication credentials are always anonymized :

For the anonymizing of the RTP packets the voice is replaced with a beep tone :
The result of this Audit gives links to the anonymized voice in the generated wav files :
