Hi. I am struggling with this. We have a landline which is on divert to a pay monthly mobile. The divert works fine unless we are unable to answer and instead of it being picked up by the voicemail it just gets cut off.
If I use a different O2 number, it works fine, so I know it can be done. And if I set up the SIM to divert to another number, for example a different mobile number, it works fine as well. But if I try and get voicemail to answer it just dumps the call.
I do not know what to try next. Anybody any ideas?
