Due to echo problems <br>(that was before Oslec and others), we quickly switched to cards with <br>hardware-based EC.<br>So we use exclusively Digium B410p cards that provide 64ms tail EC.<br><br>For several reasons we'd like to switch to external BRI gateways like <br>the Patton smartnodes (the price is getting really close to a B410p).<br><br>I'm however curious about their HW EC. I see in the datasheets that it <br>only has 25ms tail per channel (pri are 128ms, but not BRI).<br>Are some of you using these gateway and do your experience (many) <br>echo problems on calls ?<br><br>Our other alternative is to use sangoma cards that have 128ms HW EC <br>and seem more stable overall, but it is yet a bit more expensive.<br><br>Thanks for your feedback.<br><br>Regards,<br>Gaetan<br><br><br>_______________________________________________<br>-- Bandwidth and Colocation Provided by <a href="http://www.api-digital.com">http://www.api-digital.com</a> --<br><br>AstriCon 2009 - October 13 - 15 Phoenix, Arizona<br>Register Now: <a href="http://www.astricon.net">http://www.astricon.net</a><br><br>asterisk-users mailing list<br>To UNSUBSCRIBE or update options visit:<br> <a href="http://lists.digium.com/mailman/listinfo/asterisk-users">http://lists.digium.com/mailman/listinfo/asterisk-users</a><br></div></blockquote></div><br></body></html>
