Hello Gareth,
I did as you suggested and Virgin voicemail is working, but my landline phone still only rang ONCE and I would not know that I had missed a call or got a message!!!!!
Nevertheless I experimented with my own 'brand new answerphone' call settings. I changed the number of rings from the auto setting (5) to my selected choice of six. Wunderbar it's now working perfectly, I can now recieve calls as well, provided I pick it up before six rings. Incidently the minimum setting is TWO, so the fault was never with my old or new answerphone.
So Gareth, we got there in the end, thankyou.
Now It's just a question of compensation?
Regards Harvey
