I've just tried ringing my phone from an adjacent landline. I can hear the ring on the landline but it seems to take ages before the Hero starts ringing. It's as if it is unwilling to come out of its coma.
Obviously, if the thing is set to go to VM after say 8 rings, I might only get 2 rings on the device as a result of this delay.
I'd love to know if there is any other setting that can be tweaked, other than the useful suggestion above.
I guess I'm wondering why it takes so long for the connection to activate.
PS: I've just tried extending the time taken before going to VM as described above and it works a treat - thanks. (Would still like the phone to "wake up" a bit quicker though!)
