Best-effort Call Answering

If some numbers have been set using &ZI command (as can be
seen by the AT&ZI? command) and they are not matched with the
address of the incoming call, the TA128 will, by default, ignore the
call as it may be intended for other devices that share the same S/T
interface (S0 bus) with the TA128.
If you want the TA128 to answer inbound calls as often as
possible, you can set the best-effort call answering bit as follows:
S119.3=0 - Answer calls only when numbers match (by
default).
S119.3=1 - Best effort call answering.

Ambiguity Resolution Switch for Voice Calls

For a voice or voice-band-data call, if the &ZI number assignment
can tell which of the analog adapters is being addressed, then the
call will be delivered to the proper destination. Sometimes,
ambiguity of address matching may exist. This may happen if the
&ZI numbers of the various protocols are either unassigned or not
matched. In this case, users may wish to set the priority of
answering a call by the analog adapter, Phone 1, or the analog
adapter, Phone 2. The AT&Ln command sets the address
ambiguity resolution flag:
AT&L0 - Analog adapter 1 has the higher priority to answer a
voice or voice-band-data call; if analog adapter 1 is busy, the
call will be routed to the analog adapter, Phone 2.
AT&L1 - Analog adapter 2 has the higher priority to answer a
voice or voice-band-data call; if analog adapter 2 is busy, the
call will be routed to the analog adapter, Phone 1.

Multi-Auto-Answering of Data Calls

For an ISDN data call, if the TA128 can exclusively determine the
protocol to be used by means of the information conveyed by the
