Tone signal when the phone picks up the call


New Member
When I mute all mp3 sounds the tone signal remains hearable during the call attempt. The problem it is inconsistent: load and clear with some operators, tones cannot be heard at all with others. Sometimes there's a latency.
Can I disanle these tones somehow? Whould it require significant chages in the code?

These tones usually accompany the 183 SESSION PROGRESS status produced and sent by intermediate VoIP gateways.
The client receives such tone signals and plays the as usual audio stream. Unfortunately, for now you can't turn this off.
