Stage 11: Inbound Traffic

This suggests that all the circuits are now working and ready for call traffic, but you need to test that this is the case, as described in this section.

To test, make an inbound call to a valid number on the Blueworx Voice Response Client, then select from the following outcomes:

Outcome	Action
After dialling, silence is heard	Go to stage 11a
After dialling, a busy tone is heard, or a similar verbal report	Go to stage 11c
You successfully connect to Blueworx Voice Response, and receive the selected service	Go to Stage 12: Testing outbound calls

Stage 11a: Verify that the call is coming into a Blueworx Voice Response client

To simplify this task, select one Blueworx Voice Response client, which should be configured to receive inbound call for the dialled service. Take the remaining Blueworx Voice Response systems out of service. Now perform the following steps:

Log into the selected system as dtuser.
Enter ss7view –message.

Make an inbound call to the selected service If the inbound call is successfully answered, the following output is displayed:

13:29:38.264:0000:    IAM/ISUP_SETUP[1234]  ---------->>
13:29:38.265:0000:                                  SL_CALL_SETUP_IND ---------->>
13:29:38.265:0000:        <<---------- ACM/ISUP_OGC_SELECTED
13:29:38.265:0000:        <<---------- ACM/ISUP_ALERT
13:29:38.268:0000:                       <<---------- SL_CALL_ANSWER_REQ
13:29:38.268:0000:                       SL_CALL_ANSWER_CNF [SL_REPLY_SUCCESS] ------->>
13:29:38.269:0000:        <<---------- ANM/ISUP_SETUP
.......
13:29:41.846:0000:                       <<---------- SL_CALL_TERMINATE_REQ
13:29:41.846:0000:        <<---------- REL/ISUP_RELEASE[Cause:CSV_NORMALCALLCLR]
13:29:41.861:0000:    RLC/ISUP_RELEASE ---------->>
13:29:41.862:0000:                       SL_CALL_TERMINATE_CNF [SL_REPLY_SUCCESS] ---->>

Now select from the following:

Status	Action
There was no output	Go to stage 11b
The IAM/ISUP_SETUP was shown but no SL_CALL_SETUP_IND	Go to stage 11c
The SL_CALL_SETUP_IND was shown but no SL_CALL_ANSWER_REQ	Go to stage 11d
The sequence as shown in the screen above (down to the line ANM/ISUP_SETUP) was displayed	Go to stage 11e

Stage 11b: An inbound call is not being received by the SS7 cluster

Verify with the network operator that the configuration is correct and has been enabled.

Stage 11c: SS7_D7 has rejected the call request, possibility with invalid parameters.

This condition should be supported by alarms appearing in the Blueworx Voice Response System Monitor. If further help is required collect event and trace data (the test will need to be repeated). For more information see Collecting event and trace information. Pass this information to IBM support for assistance.

Stage 11d: Possible problem in the call-answering mechanism of Blueworx Voice Response

Refer to the relevant documentation for the application language used, to verify that it has been correctly assigned.

Stage 11e: The inbound call is connected and the application is running.

Try the following steps:

Ensure that the application is delivering voice information.
Ensure the voice bearer cables for connections to the associated DTTA cards are present, and in the correct order (voice could be transmitted down the wrong cable).
