Most likely your Bluetooth/Voicecontrol module is breken or has a software fault. You should reset the module first. This can be done softwarematically with a diagnostic system, by disconnecting the Bluetooth/Voicecontrol module connector or by removing the radio fuse for about 15 minutes (mind your radio code!).
If resetting the module does not solve the problem the Bluetooth/Voicecontrol module appears to be defective in most cases.
Another possibillity is that your Phone is not compatible with the Bluetooth/Voicecontrol system of your car. A 2007 Focus MK2 has the old Bluetooth/Voicecontrol system which can not be updated. This means that allmost all newer Phones are officially not supported. Newer Phones may not function correctly with the outdated Bluetooth/Voicecontrol system of the Focus MK2.
