 T.38（IP-based）
 T.30（Pass-through）
3.6.2 Explanation of T.38 and Pass-through
T.38: T.38 is used to transfer faxes over IP networks in real time. It could convert the analog fax signal
into digital fax signal and could transform it back from T.38 into analog signal. Under the T.38 mode, fax
traffic is carried in T.38 packets.
Pass-through: Under the pass-through mode, fax signal is not converted and fax traffic is carried in RTP
packets. It uses the G.711 A or G711U codec in order to reduce the damage to fax signal.
