If anyone can offer any advice it would be very appreciated.
We have voicemail on our phones, then a few days ago the voicemail function stopped working.
Trying to programme the voicemail just gives the messege invalid as if the voicemail function is not installed.
We had an engineer out to look at the phones and he suggested that the voicemail module must need replacing.
I have replaced the voicemail module and done a full restart - Turned power off on the unit and at the mains, disconnected the battery for a few seconds then turned everything back on. The voicemail function still does not appear on the system.
Can anyone advise if it is likely I have bought a dodgy voicemail unit or if it is a programming problem with the phones?
