Terminating Calls
Delay Before Seize Acknowledge
Delay before the TSP sends seize acknowledge back once it detects a seizure from
equipment under test.
Delay Before Answer
The delay before the TSP sends an seize acknowledge once it detects a seizure from the
equipment under test.
Wait for Dialing Start
This only applies when the Template is used in a Dialed Control Set type. It’s the time the TSP
will wait for the first digit to be sent before timing out
Inter-digit Dial Timeout
This only applies when the Template is used in a Dialed Control Set type. It’s the time allowed
between the dialing of digits before the TSP will timeout on the call.
Delay Before Ringback
In a Dialed Control set, the delay from the dialing of the last digit of a valid Phone Number to
when the TSP starts to send Ringback. In other control sets, the delay from the end of dial tone to
when the TSP starts to send Ringback.
Ringback Length
Length of time the ringing cycle will be played by the TSP to the equipment under test.
All Calls
Delay Before Message
The delay before an audio file is played if one has been assigned to the channel. Does not apply
to End-to-End calls.
Call Duration/Disable Timeout
Controls the length of the call before the TSP starts a new call. Clicking on the box adjacent to
Disable Timeout will allow the call duration to be determined by when the TSP receives an
on-hook indication. Does not apply to End-to-End calls.
Far-End Disconnect Time
Time the TSP delays after receiving an on-hook from the equipment under test before it goes to
an on-hook state.
Disconnect To Start Of New Call
Time TSP delays after going on-hook before resetting for a new call.
