[Asterisk-Users] Re: Problem with Grandstream bt100

[Derek Conniffe]

I had a budgetone 100 that I'm fairly sure I powered down during a flash 
upgrade and it wouldn't boot - it just kept flashing the keypad 5 times, 
then pause, then 5 times, then pause, etc.  I tried powering off, 
waiting, powering on, waiting,  praying, everything.  I though it was 
dead and then about 12 hours later it suddenly came back to life.  It 
was connected to the internet (behind a NAT firewall) all the time.  
Weird.....
