I am continuing to have problems with echo on a PRI line. It is usualy an issue on long distance phone calls. I have changed the echo cancelation settings in zapata.conf with no luck. It seems to have little effect if anything makes things worse. Currently my zapata.conf file is as follows:
With these settings I have received less complaints but am still getting a few.
I know my PRI card (TE120P) does not have hardware echo canceling, would switching to the TE122 with the echo canceling module fix my issue? Are there any other settings I should be trying? I have done much reading on the issue and know there are some software modules that might work, but could never really find how successful they are.
Thanks for the help,
