The dropped calls do happen most of the time during conference calls. Is the silence detection just for the MIC (i.e., my voice) or does it also listen to the incoming audio, because I get drops when other people are talking but I may not be talking. I'm often on MUTE during conference calls for long periods of time, certainly more than a minute.
My understanding is the silence detection is for the other side of the conversation (what you are hearing), not your voice.
I wonder if maybe the volume coming in from the other side of your conference calls is too low to consistently exceed the threshold that is considered "not silence". If that doesn't make your head hurt, as it does mine, then maybe it's just me.
To adjust the silence detection:
Physical interface -> LINE port -> PSTN Disconnect Detection ->
1. DetectFarEndLongSilence (checked = on, unchecked = off, default = on)
if the above is "on" then:
1.a SilenceDetectSensitivity (low, medium or high, default = medium)
1.b SilenceTimeThreshold (a value in seconds, default = 60)
So, what does all this mean? Here's my guess. Either turn DetectFarEndLongSilence off, or leave it on and adjust one or both of the other two. The manual indicates SilenceDetectSensitivity "Low" means harder to detect silence and "High" means easier to detect silence. I'm not positive if you'd want "High" or "Low" because the voices in my head are arguing with each other as to what this really means. I've fall'in into an infiniteloop and can't get up (notice I did not include the word
it). It's like chosing between the blue pill and the red pill (the obvious blue pill jokes aside). I'd pick blue, er, I mean I'd pick SilenceDetectSensitivity "Low" harder to detect silence (chuckle, "
harder"). Geez, it's after 11 am and I've not had any coffee. So your actual mileage may vary. I love when people say that (YAMMV) when they aren't really sure what they're talking about. It's like "Well, it worked for me. I don't know what
your problem is."
