Send Fax
Outbound faxes require one RADIUS packet exchange for real-time fax clients to retrieve
information for the sending account. For fax ATAs, one or two additional calls are made to
retrieve more information. The caller-id from the fax session from an ATA is used to query for a
matching DID, allowing for information to be retrieved that is regarded as specific to sending line
on the ATA. If a matching DID is not found, the session still proceeds without any error.
