40 < bad quality D410E 4x2,4Ghz

Hi

I have problem like in http://bbs.openvox.cn/viewthread.php?tid=891& ;extra=page%3D3

When I have more than 40 calls in one time I get very low quality, sound is terrible.

Load balacing is 0.5

Eryler I was use only sangoma quad without hardware echocancelation and on the same machine was working fine with 120 councurent calls.

Please remove the echocanceller=mg2,xxxx in system.conf and reboot system to test.
show the server's dmesg information

When I disable echo cancelation then works fine but on sangoma was work fine with echocancelation on.

Can you tell me how many PRI port are in your sangoma card?

the same 4 x E1 ,
A104 Quad Voice and Data Card
thx
Grzegorz

Did the A104 have hardware echocancel?
