I have bought the A400P card with 2 FXO modules for installation with Asterisk. Unfortunately it works with very low volume and bad sound quality. I tried to increase rx and tx gain but with almost no luck. And I tried fxotune and different echo-cancellations. And I tried this card with Elastix 2.3 and with clean Asterisk-10 installation on CentOS 6.2. There was no difference. The card produces much lower volume than ordinary analog terminal on the same line.
What else can I do to increase volume and to improve sound quality?
Could you give me SSH infor ,So I can check and try to fix your problems. My E-mail is This email address is being protected from spambots. You need JavaScript enabled to view it.
