I am having trouble with a strange behavior of outgoing calls using an OpenVox FXO card. I have Asterisk with DAHDI.
The strange thing with outgoing calls through my analog line is that after I dial the number, instead of passing the call, the system returns the typical phone tone (as if I picked an old analog phone). Then I dial the numbers exactly as it happens when I use a normal analog phone (I hear the typical “beep” when pressing the numbers). The call goes through and works but with a horrible echo.
I’m not sure what kind of information I should provide to help you troubleshoot this issue with me. Any help is appreciated.
