I am wanting to change the ring time before forwarding. I have found this Wiki page about forwarding. I am successful making only one change: I can change it to forward within 5 seconds. Of course, the phone actually rings from the network for about 2-3 seconds before your phone actually starts ringing, so that's no good. Anyway, once I change it to 5 seconds, I cannot change it to anything else. I tried changing it to longer times, such as 10 seconds before trying 5, and it didn't work. Anyone have any success changing forwarding timing?
