On Page 2, set the FAX Mode field to t.38-standard. The Modem Mode field should
be set to off.

Leave the FAX Redundancy setting at its default value of 0. A packet redundancy
level can be assigned to improve packet delivery and robustness of FAX transport over
the network (with increased bandwidth as trade-off). Avaya uses IETF RFC-2198 and
ITU-T T.38 specifications as redundancy standard. With this standard, each Fax over
IP packet is sent with additional (redundant) 0 to 3 previous fax packets based on the
redundancy setting. A setting of 0 (no redundancy)

is suited for networks where packet

loss is not a problem
