Did you search the maillist archives for hybrid echo cancellation?
Hello
In the following setup:
call coming from a pstn line -> into FXO card -> asterisk -> SIP phone
i get an incredible loud echo in the SIP phone (about 0,5-1s) (everything
i
speak into SIP phone microphone i hear in its speaker). The person calling
from PSTN is not getting any echo.
Which piece of the call could be causing the trouble so i can look into
it?
thanks,
Marek
