在VoIP通话中，iphone gsm通话静音铃声

Question

is there any way to to mute or lower ringtone of a gsm call on iphone.

the problem is when someone has a voip call in progress and the gsm call comes thru, then one probably needs to see a physician. is there anyway to temporarily mute or lower the ringtone programmatically?

Answer 1

在Apple重新考虑之前，无法以编程方式更改铃声音量，从而给开发人员一些自由。
