Hi Zoie,
Thanks for the prompt reply.
I managed to get through to 150 and they have arranged to remove the 1571 voice mail service sometime tomorrow. Can you confirm that, once this is done, the phone will ring indefinitely and will not be limited to a certain number of rings. We have an answerphone built into the phone so that will pick up any messages after a much longer set number of rings if we switch it on. Ten rings wouldn't necessarily give her enough time and, at 92 years of age, she is in danger of falling as she rushes to get to the phone in time.
Thanks,
Dave
