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.
