T.38, a protocol that describes how to send a fax image data over the IP network. T38 is introduced
for more efficient and robust transmissions compared to use the same method as voice
communications.
There are pros and cons of both approaches described above. Consult your service provider for
appropriate configurations when needed.

Configure CDR Setting (Call Detail Records) from VoIP. It is a file that contains attributes and system usage
that are specific to a single instance of a phone call or other communication transaction that was handled

automated record of the length of each telephone call.
