Apparently the phone rings for 21 seconds or 7-8 rings before voicemail cuts in. It's more like 5-6 rings for us, but whatever it is, it's far too soon! We can never reach the phone in time. Please make this an adjustable setting, not fixed as it is now. We would like about 12 rings before the voicemail cuts in to give us a chance to actually reach the phone to answer it. I really hope you listen to this suggestion and realise not everyone can reach their phone in 5-6 rings if they're upstairs or out in the garden.
