My device is running: 3.2.2 (Build: 5921EX), is this the latest version?
Over the past few days it works for the first call after a reboot. After hanging up and the picking up the receiver there is only a white noise sound, no beeping, no dial tone. It requires a reboot to get past this... very annoying and weird.
- That is the latest firmware.
- This not a firmware issue.
- Try using a different telephone plugged into your device instead of the one you are using now.
I have this as well. .right before it started giving me the Service Provider has not responded message. No fix for it that i know, other than rebooting the device (which isn't a fix).
