The default is:
modem passthrough system
When using the default (system) configuration, the dial-peer FAX passthrough
configuration is defined by the configuration in voice service voip. When system
is used, no other parameter is available.
When the NSE is configured in the FAX passthrough command in the dial-peer
level, the FAX passthrough definition in dial-peer takes priority over the
definition in voice service voip. The payload-type number, codec, and
redundancy parameters can also be used.
For example,
modem passthrough NSE codec g711ulaw
means use the NSE payload-type number 100, G.711ulaw, no redundancy in the
fax passthrough mode.
To disable FAX passthrough, turn on bits 14 and 15 of the ConnectMode in the
Cisco ATA 186 configuration. On the Cisco gateway, enter:
no modem passthrough
Some users might want to set one or both lines of the Cisco ATA 186 to pure
G.711 FAX mode. This mode allows the FAX machine connected to the
Cisco ATA 186 to communicate directly with the FAX machine at the other end
of the call with no FAX signaling events between the two FAX machines.
You can configure the Cisco ATA 186 to operate in FAX mode on one or both
lines.
