Particular switches transmit call information out of band using a serial
line called the exchange data link. When Blueworx Voice Response is directly connected
to such a switch and is not receiving the call information, check the following:
- Is the physical connection complete?
- The connection between the Power System and the switch is an RS232 line,
either with or without modems. Ensure that the line is still connected correctly
at both ends. Blueworx Voice Response for AIX: Installation describes how to connect the exchange
data link line.
- Has the AIX configuration been changed?
- Information on the exchange data link carries an identifier to identify
the channel to which the data pertains. Check that the system parameters that
define the exchange data link are correct. Use the information provided in Blueworx Voice Response for AIX: Installation to redefine the exchange data link device to AIX.
- Has the Blueworx Voice Response telephony configuration been changed?
- The Blueworx Voice Response telephony configuration includes a number of parameters that
define the exchange data link connection and the format of the information Blueworx Voice Response expects
from the switch. Use the information provided in Blueworx Voice Response for AIX: Configuring the System to
correct the Blueworx Voice Response exchange data link configuration.
- Are the exchange data link channels identified correctly?
- Each channel on the exchange data link carries information about one
signaling channel on the trunk line. Information identifying the exchange
data link channel is part of the Blueworx Voice Response telephony configuration. If the channels
are not identified correctly, Blueworx Voice Response cannot receive the exchange data link
information. Use the information provided in Blueworx Voice Response for AIX: Configuring the System to
correct the exchange data link line identifier that correlates with each Blueworx Voice Response channel.
- Are you using a signaling process that you developed yourself?
- Have you configured Blueworx Voice Response to use your signaling process? (See Blueworx Voice Response for AIX: Configuring the System for more information.)
Check that your signaling process
is still running.
Check that your signaling process is receiving the
call from the network.
Check that your signaling process is sending
the SL_CALL_SETUP_IND primitive to Blueworx Voice Response, and that the sl_send_indication()
subroutine is returning successfully. Check that the sl_call_data_st
structure in the SL_CALL_SETUP_IND primitive has been filled in correctly.
Use signaling interface tracing to the see the primitive sent by your
signaling process to Blueworx Voice Response. For information on tracing signaling interfaces,
see Blueworx Voice Response for AIX: Programming for the Signaling Interface.
