5.3.2. PSTN Pass Through
When Unicorn 3112 is out of power or loses registration or if the network connection is
down, the RJ 11 line jack on the side of Unicorn 3112 will function as a pass through
connection for PSTN calls. Users will be able to use the same analog phone for PSTN
calls.
5.4. FAX
Unicorn3112 supports FAX in two modes: T.38 (Fax over IP) and fax pass through. T.38 is
the preferred method because it is more reliable and works well in most network
conditions. If the service provider supports T.38, please use this method by selecting Fax
mode to be T.38. If the service provider does not support T.38, pass-through mode may
be used. To send or receive faxes in fax pass through mode, users will need to select all
the Preferred Codecs to be PCMU/PCMA.
