By setting S register 61=1, all outgoing calls will be TollMizer

Alternatively, you can place TollMizer calls on a call by call
basis using the command ATDD <telephone number>. To
manually dial a TollMizer call on a call-by-call basis, type the
following:
ATDD <telephone number>
An example is as follows:
ATDD 1 908 555 1212
Note that the TollMizer feature is available for Multilink PPP
calls as well.
Before using the TollMizer feature, check with your Internet
service provider to verify that they support it and that it is
enabled.
The device you are dialing into must be capable of generating
the 2.1 kHz tone needed to disable the echo cancellers on the
line. Refer to the Readme file located on the software diskette
for more information.
Receiving ISDN Data Calls
The 3C882 ISDN modem can receive incoming
circuit-switched data calls from other 3C882 ISDN modems
or from ISDN devices.
When Auto Answer is disabled (S0=0, by default), a RING
message is delivered to the RS-232 port upon reception of an
incoming data call to the 3C882 ISDN modem. Enter the
command AT A to answer the incoming data call. A
CONNECT message is then delivered to the RS-232 port upon
successful connection.
