I had to do a hard reset, and now my Hermes/Vario II has the standand WM5 scheme.
I can hear "keypad tones" as I press keys, and even hear them 'in call' - but they don't seem to be received / registered at the "other end", meaning I can't navigate voicemail/IVR systems, or use 'calling cards'.
Changing the settings within "Phone", Options, Sounds, "Keypad" to either long tones, short tones, or off has no effect.
I've wondered if it is "using USA style tones", but have checked "Regional Settings" and they say "English (UK)".
I can't see a cure listed in the manual.
I've asked T-mobile CS for help with either:
a) setting the DTMF tones, or
re-installing the T-mobile customisation / theme, but they say it "can't be re-installed - once its gone its gone".
So, has anyone else had this and found a work-around?, or is there a setting I've missed?
Any help gratefully received!.
