you won't be able to disable this message... a firmware update will be needed to disable it. Typically, I had this message on unlocked phone not bought with my provider...
that said, conditional forwarding is call fowarding when you cannot answer the call... essentially it's there to forward the calls to your voicemail if you don't answer.
you can try to disable this and reenable it with these codes :
Call forward busy: *67# to turn it on, #67# to turn it off. To program the number, this is **67*(destination number)# Call forward no reply: *61# to turn it on, #61# to turn it off. To program the number, this is **61*(destination number)# Call forward not reachable (device turned off): *62# to turn it on, #62# to turn it off. To program the number, this is **62*(destination number)#
I don't know if you will be able to program a different number if you have voicemail enabled on your account.
yes my vocie message is on, and I have to keep it on. The signal reception in my house is very weak, the phone support vowifi, but videotron doesn't allow it on this phone. I have to keep the voice message, in case some of the important calls.
