I install Teleflow 2006 with board Dialogic D/120JCT-LS, I need when anwers call (Icon Place Call) the Teleflow after 4 seconds the silence Hang up call, actually wait aprox 30 seconds the silence.
The dialogic system release is SR 5.1.1 and SP-SR5.1.1

TheSilence timeout(ms) field =1000 and Maximum voice length (ms) filed= 60000 but Teleflow Server send error in log:

Telephone Number '@NumDiscar' evaluates to '353'
Rings before TIMEOUT is '2'
Silence timeout is '1000'
Maximum voice length timeout is '60000'
Place call to 353
and wait for up to 2 rings
Connect on CED
Do not connect on SIT
Determine initial voice length with silence timeout of 1000 ms,
and overall voice length no greater than 60000 ms

FATAL

In the properties of your PlaceCall step, you need to empty out the fields "Variable to receive initial voice length" and "Silence TIMEOUT (ms)". Your application will be able to dial out after that.
