8.137. REDIAL -- Redial the Last Dialed Phone Number
Executing this command causes the Vortex to redial the last number. The last number is defined as all
the digits that were dialed since the phone was last taken off-hook. Like the
DIAL command, if the
phone is not already off-hook, this command will take it off-hook automatically.
Example Description Status Message
S01REDIAL
Redial the last dialed phone number.

8.138. REFASGN -- Assign AEC Reference to Input Channel
This command assigns an AEC reference signal (R1 or EF Bus) to an input channel. Only input 1 has
echo cancellation, so the command is only valid for that channel. Assigning 1 to the input channel
selects AEC Reference 1 (R1). Assigning 3 to an input channel selects the EF Bus Reference. The EF
Bus reference is an AEC reference that is placed on the EF Bus by one (and only one) of the linked
Vortexes. See the
BUSREF command for more information about the EF Bus reference. Assigning
REFASGN a value of 2 is not supported on this device. The value of 2 is only supported on devices
that can build a second AEC reference (i.e., the EF2280, EF2241).
Although this command is a channel integer command, the increment and decrement operators (>
and <) are not supported for this particular command.
This command is a channel integer command. See
Section 6.3 and Section 6.2 for more information
on this type of command. The minimum and maximum values for this command are 1 and 3,
respectively.
This command is saved to non-volatile memory only as part of a preset. The state of this command
will be restored after power-up only if a preset is saved and that preset is set to be the power-on
preset.
