We provide this utility.
You can verify numbers behind IVRs by including ‘w’ characters in the Extension parameter. Each ‘w’ character tells PastorsLine to wait 0.5 seconds instead of playing a digit. This lets you adjust the timing of when the digits begin playing to suit the phone system you are dialing.
For example, the extension “wwww2wwwwww5wwwwww9′′ waits two seconds before sending the digit 2, followed by a three-second wait before sending the 5, and finally another three-second wait before sending a 9.
