This morning I set up voicemail and it worked fine, but I thought time for voicemail to switch in too long. So I tried **61*123*10# for iPhone, then found time was too short so I changed again to maybe 14 seconds, and maybe did again. But now I find my voicemail does not switch in when someone phones, instead the incoming call simply ends after approx 10 rings, almost like I pressed the end call button. How can this be🙈? How to resolve 🧐?
Any help appreciated 🙏.
