Answering V.120 Calls 9.3
V.120 answering can be enabled from the command interface by setting register S0 for the appropri-
ate ASY port to a non-zero value. For example:
ats0=1
You should ensure that you have set S0 for the correct ASY port by either entering it directly on
that port or by using the AT\PORT command to select the correct port first.
The actual value used for the parameter sets the number of rings the unit will wait before answer-
ing.
Finally, you must ensure that there are no conflicts with other protocols configured to answer on
other ASY ports. This can be done by disabling answering for the other ports/protocols or by using
the MSN and/or Sub-address parameters to selectively answer calls to different telephone numbers
using dif ferent protocols.
For example, if you have subscribed to the ISDN MSN facility, you may have been allocated say four
telephone numbers ending in 4, 5, 6 and 7. You could then set the MSN parameter for the appropri-
ate
V.120 instance to 4 to configure V.120 to answer only incoming calls to the MSN number ending in
4.
You should check that if PPP answering is enabled you have NOT selected the same MSN and Sub-
address values for PPP. If they are the same, V.120 will answer the call ONLY if S0 is set to 1. Other-
wise, PPP will take priority and answer the call.
