Callservices(4bnu)
Callservices --
incoming call service types
Synopsis
/etc/ics/Callservices
Description
The /etc/ics/Callservices file contains
information about which services can be used by
an incoming call.
All entries must contain the following five fields in the
order shown.
If a field is to be left blank, then that field must contain a dash (-).
Blank lines, and lines that begin with white space,
a tab, or a hash sign (#) are ignored.
The fields in the Callservices file are defined, in order, as follows:
- ``Type''
-
- acu
-
Indicates that the link to a remote computer
is made through an Automatic Call Unit (automatic dial modem).
- acu_fax
-
Modem in fax mode.
- direct
-
Indicates a direct serial link to another computer or a switch.
- isdn_async
-
ISDN adapter in V120 mode.
- isdn_fax
-
ISDN adapter in fax mode.
- isdn_sync
-
ISDN adapter in synchronous mode.
- isdn_video
-
ISDN adapter in video mode.
- isdn_voice
-
ISDN adapter in voice mode.
- tcp
-
TCP/IP local area network (LAN).
- ``ID''
-
The telephone number that will accept the call for the service.
Any specifies any telephone number.
NOTE:
The facility to obtain the called ID
is not supported in UnixWare for modems.
Specify Any as the ``ID'' of such devices.
- ``Device''
-
The name of the device through which the call came.
Any specifies any port.
- ``Service''
-
The pathname of the service to invoke.

Examples
# /etc/ics/Callservices example
#
isdn_sync Any Any /usr/bin/pppsh
acu Any Any /usr/bin/shserv
isdn_sync 1234 /dev/net0 /usr/bin/pppsh
isdn_async 6543 /dev/net0 /usr/bin/shserv
acu_fax Any Any NULL
isdn_fax Any Any NULL
isdn_voice Any Any NULL
isdn_video Any Any NULL
In the above example, a call type of isdn_sync invokes
the PPP shell service, /usr/bin/pppsh.
If the type is acu then the service to be invoked is
/usr/bin/shserv. If the call type is any of
acu_fax, isdn_fax, isdn_voice or
isdn_video then there is currently no support in
UnixWare 7 to handle such requests, so the service is set to
NULL. If a third party application were to become
available to deal with any of these, then the Callservices
file can be updated on the installed system.
