Diagnosing PSTN Protocol Issues
13. Click the MakeCall button to start the call. Notice that the CallInfo fields are updated after a
call is made, enabling you to monitor the state of the call. For example, the Called ID (DNIS)
field shows the telephone number dialed by a caller. The Caller ID (ANI) field shows the
telephone number of the incoming call. Also the CallState field shows the state of the call
(such as Connected or not) and the ChanState field shows the state of the channel (such as
Active or not).
14. For the inbound channel (lower pane), click the Accept button to accept the incoming call.
Notice that the CallState for the inbound channel will show “Accepted.” If the expected state is
not being displayed, it may indicate a protocol configuration problem.
15. For the inbound channel (lower pane), click the Answer button to answer the incoming call.
Notice that the CallState for the inbound channel now shows “Connected.” If the expected
state is not being displayed, it may indicate a protocol configuration problem.
16. After you have verified that a call is successfully made, click the Release button for the
outbound channel to end the call. The CallState for the inbound channel will show
“Disconnected”. The CallState for the outbound channel will not change yet.
17. Click the Release button for the inbound channel to end the call. The CallState for the
outbound and inbound channels will show “Null / Normal”. The ChanState for the outbound
and inbound channels will show “Idle”. If the expected state is not being displayed, it may
indicate a protocol configuration problem.
Note: In a channel level view, a log pane is displayed below the Te xt Log button. This log
pane only displays events for that particular channel. To change the view between text
format and graphical format, click the Text L og button.
