I am using the VPMADT032 echo cancellation module
attached to a Digium
TE121B PCI express card. The incoming phone service is a PRI. Can I
still use fxotune if my incoming lines are all digital? I will try echocancel=256. I have also tried OSLEC and still get echo with that also. Thank you.

VoIP works as fine as conventional telephony once it's correctly set up.Try echocancel=256 instead of echocancel=yes and also run fxotune (check the man page). If that all fails, install OSLEC. It's an excellent free software echo canceller, that works much better than Asterisk's default MG2.

I can hear my voice in the ear piece of the phone with a slight delay. Is this just a fact of life with VoIP, or is there a better way to reduce line echo? Again, for reference, I am using the VPMADT032 echo cancellation module attached to a Digium TE121 PCI express card. The incoming phone service is a PRI.

The system below is out of Livonia, with an AT&T PRI as well. Note the rx/txgain entries, it may be useful as well: switchtype=national context=pri signalling=pri_cpe echocancel=yes echotraining=yes echocancelwhenbridged=yes rxgain=-1.0 txgain=-4.0 _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users_______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users |
