RE: best Jitter and Echo values
Hello Support-Team,

sorry for my bad english ;-)

When I get a phone call and I talk, I hear my self silent in the background approx 0,5 sec. delayed. This is what I mean with "Echo effect".

I searched in google and found that this effect most happend when the buffer value of Jitter or Echo is not set proper.

Jitter seems to be a buffer which should suppress this effect.

The phone call quality is like in the early first days when VoIP comes up when everybody has a 56k modem. I can remember there was this echo effect too.

We use a 50Mbit Down- and 4 Mbit Upstream line which is only used for 6 VoIP Phones. In worst case 4 people make phone calls at the same time. So it could´nt be a bandwith problem in my eyes.

I can´t find a parameter in the webinterface of the VP530 which I could change to test if can get rid of the echo effect.

Also when I get a phone call, the first syllable of the call did´nt reach me. I think this is the same problem like the echo effect.
The transfer or buffer time is not correct and so some bits of the phone call are get lost.

I assume that this mainly happend with phone calls from VoIP to traditional ISDN Phones.

Hope this helsp a bit.

Best regards.
