Initial Firmware Version
Defines the time in milliseconds that the phone waits between sending new commands to the USB headset.
The phone needs to wait for an answer for some headset commands (e.g. offhook, onhook) depending on the headset. Sending a new command to the headset before the phone gets the answer to the last command could confuse the phone. In some cases it leads to a toggle between onhook and offhook. In this case it could help to increase the delay.
