Reconfigure the button to dial your own voicemail:

- Get to your iPhone’s number keyboard

- Type *5005*86*xxx# (where xxx is your voicemail number). In Switzerland, the standard number is +4186YYYYYYYYYY (where YYYYYYYYYY is your phone number: ex: 079 123 45 67). Example for a Swiss number: type *5005*86*+41860791234567#

- Press the “Call” button, wait a few seconds… and it’s done! Now, when you tap the Voicemail button, it will dial your own voicemail.

Remark: you can also configure it with your national number (0791234567) instead of the international one (+41791234567), but it won’t work when you are roaming…

Tested on 1.1.1 (unlocked with AnySIM 1.1) and 1.1.2 (OTB with Turbo SIM)
