In my hunt to track down my echo issues, I tried disabling all echo cancellation, suppression, adaption, on my SPA-2000 (Advanced section of the config, under Line 1/2). Then calling from one local extension to another. (SPA-2000 Line1, to Line2 on the same device)
I was pretty shocked with the results, the echo was HORRIBLE! I even tried 3 different analog phones. Now, once I turned the echo cancellation back on, I tried a few tests to see if I could hear any echo. The test was saying: "test", "check", and hitting my desk with a single finger fairly hard. When I would say "test" and "check" I would try all sorts of different voice tones, volumes, etc... I found I could still hear echo when doing this. When I hit the table with my finger (while still holding the phone to my ear and not talking of course), you could _really_ notice the echo. I could hear the "hit" perfectly clear coming back through the phone. As well if you change the Input/Output gains under the Regional section, cranking them both up to 5 or so, you could easily hear the echo, and the SPA-2000's poor attempts to cancel it. I'm curious to know if anyone else using SPA-2000's have the same issues. I wonder if when calls are made from SPA-2000's to PSTN numbers through Asterisk, asterisk is just amplifying the SPA-2000's own echo somehow. Any test results are welcome, I would be very interested if other people are unable to replicate my results. -- Mike Benoit <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
