z1 forward all calls does not work

[Wrightal123]

Z1 C6903 on Kitkat 4.4.4, build 14.4.A.0.108, UK on Vodafone

I have had this problem in 4.2 and 4.3 and still not working in 4.4.4.  If I go to Settings/Call settings/Call forwarding and select Always forward I get the option to manually add a phone number or access my contacts to auto insert a number.  I then select Enable and the phone takes a little time updating settings, finally confirming that the Always forward option is set with the chosen phone number.

However, if I then ring my phone it does not divert the call, I just get a continuous tone.  The only number it does seem to work with is the vodafone voicemail number of 121.

Has anybody experienced this or can Sony confirm if this could be a vodafone issue on their handset?

Thanks

Have you set this feature up with Vodafone - I'm with Vodafone and had to set this feature up with them but there is a charge for doing so - So they will give you a number, It won't be the number of your forwarding number but your network will know that any calls to said number they give you is to be forwarded onto your alternative number

Thanks Thommo. Much appreciated.  I'll give Vodafone a call. Sounds like a bit of money grabbing from them as never had this issue with previous networks.
