[bug] end of missed call causes 3 tone notification to play over loud speaker
asked 2014-01-24 04:20:55 +0300
- Pick up a phone
- Call my Jolla phone
- Let it ring till it goes into voice mail
- On Jolla phone, I see missed call notification appear at the top of the screen.
- On Jolla phone, I also hear this 3 tone notification play on the loud speaker. it is the sound you typically hear from any phone - even a landline - when you fail to connect with a call. It is a 3 tone sequence with a low, medium, and high tone.
The 3 tone sequence is repeated twice on Jolla phone over the loud speaker.
Tone sequence like this? http://en.wikipedia.org/wiki/Special_information_tones

here is an audio example http://www.youtube.com/watch?v=5gw6cR_XTYg
also, a correction to my post above. the sequence is repeated 3 times (not 2)
droll ( 2014-01-24 10:35:40 +0300 )editin my case, i can reproduce this problem consistently all the time.
it seems like the software side of Sailfish is not muting the speaker or the OS is not signaling the modem to drop the call properly. just a guess. :)
droll ( 2014-01-24 10:37:46 +0300 )edit@droll: yes, at least SIT suggests that the main problem is with the telephone network. I used to hear this with N9 at one time but the problem was sth like "all circuits busy" and was fixed after filing a report to the telephone company - so I guess it's beneficial for telephone companies if callers hear these. But of course, they shouldn't break your ear.
I've heard a rumor that telemarketers' equipment can be tricked by answering the call and playing SIT tones in band :) Don't know if it's true, though.
