Re: [Asterisk-Users] Echo Cancelation on TE110P

[Michael Sampson]

It is my understanding that when you hear echo the problem is on the other end. So if a caller complains they hear echo that is something you should be dealing with, but if you hear echo that is the phone companies fault. Now with a normal phone, the phone company will only echo cancel long distance calls. For local calls the latency is not high enough to matter. But with VOIP the added latency creates echo even for local calls. I think the reason you hear it on some numbers and not others is that the phone companies are doing echo cancel on  some of those calls and not on others.

According to the users, the echo seems to be phone number dependant. They claim that certain phone numbers have echo while others dont. Are there any tuning parametes like there is for a TDM400 card?   Kerry Garrison Director of Technical Services Tech Data Pros - Orange County's Mobile IT Service Provider (949) 502-7819 x200 - [EMAIL PROTECTED] http://www.techdatapros.com   _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
