Modem Mode
Valid entry Usage
off In the off mode, a modem call is treated as an ordinary voice call. The
default mode for new installations and upgrades is off.
relay In the Avaya proprietary relay mode, Avaya devices detect the tones of
the call and use the appropriate modulation protocol or TTY to terminate
or originate the modem calls over IP network.
pass-through In the Avaya proprietary pass-through mode, Avaya devices detect the
tones of the modem call and use G.711 encoding to process the call over
the IP network.
v150mr In the v150mr mode, Avaya devices detect the tones of the modem call
and use V.150.1 protocol to transmit V-series modem signals between
secure terminals and third-party SIP gateways.
Note:
V.150.1 protocol is a standard recommended by International
Telecommunication Union (ITU) to use a modem over IP networks that
support dialup modem calls.

Use the Avaya default values.
Redundancy
Use this field to assign the number of duplicate or redundant packets that must be sent in
addition to the primary packet. You can enter a value from 1 to 3. The default value is 0.
Note:
For the pass-through and the clear-channel modes, you can use the default value or
assign 1. This field does not apply to the v150mr mode. If you set the Modem Mode field
to v150mr, the system sets the Redundancy field to display-only with the default value.
