Voicemail settings number of rings

[Jo842]

I performed an update on my iPhone last night and now it only rings 3 times before going to voicemail .

How do I change this as have tried dialling number sequence but doesn't work.

Thanks

Unless there is another settings on your iphone itself this is the only way to change it:

Have a look here under "voicemai; greetings, settings and help":
