All,

I am looking for some help in trying to fix this problem I am experiencing when using Ofono on a RaspberryPi in "carkit/HFP mode".

Currently I can make calls (originate and terminate) and audio is fine in combination with Bluez5 etc. also.

But I cannot disable CallForwarding via the dial-number command.

Enabling CFU via **21*destination-number# is working fine.

Trying to disable CFU via ##21# gives below error. Doing the same via the keypad on the mobile phone works fine.

I have the impression that somwhere this ##21# is not processed correctly but where? In ofono or in DBUS or?

Any clues?

Thanks,

Engelbert
