After calling to apprise voicepulse of the issue, duplicate calls seemed to cease.
When: an incoming calls comes in from a voice pulse trunk
Impact: trying to access the sound menu file 2 or 3 times in the same millisecond produces horrible audio quality and random hangups
A call comes in, the CLI shows perhaps two or tree copies.
Sometimes you enter on a “good” call and stay connected, no copies.
Sometimes you enter on a “good” copy and stay connected, copies present.
Sometimes you enter on a copy and stay connected, but the multiple spam channels make scratchy glitchy audio.
Sometimes you enter on a “bad” copy and it hangs up on you.
This seems to be the fault of voicepulse, but is there on asterisk that can swat down these unwanted error clone channels?
