Configuring incoming call services

Determining the call type

After the incoming call has been authorized by call filtering, the call type is determined.

There are two call types associated with modems:

There are five call types associated with ISDN adapters:

Refer to the Callservices(4bnu) manual page for more information.

Other types of call (for example, PPP connections) can be auto-detected using the /etc/ics/Autoacts file (see Autoacts(4bnu) and pppsh(1M)). This file contains a list of byte sequences and associated services. The port monitor uses Autoacts to discover which service to invoke by matching its entries against an incoming byte sequence.


NOTE: Chat scripts can interfere with the incoming byte sequences, so auto-detection may not work reliably if such scripts are being used. See pppsh(1M) for further information.
