Echoing on IP phones

[mojoputter]

We’ve had the users using the Avaya IP phones in our office complaining of quality issues on their calls. It started when we put the Qwest PRI’s in, and it started with echo. The echo cancellation was off on one of the trunks, so I turned that on, and then the issue progressed to calls that sounded tinny, or sounded like the person was in a tunnel, or robotic voice. It’s always the person on the other end of the phone that complains, and the IP phone user never hears anything. Could this issue be a setting in the network region..?

Ask Qwest of they have echo cancelation turned on for their circuits. Local trunks don't always have the EC turned on, and LD suppliers are always supposed to because the distance of the loop plays into the amount of echo that may develop on the line.

There have been situations where local suppliers (CLECs)send calls to distant CO switches thus adding distance to the geographic distance that the call has to travel. Since they are technically providing local service and not LD serrvice, they don't have echo chancellation turned on at the local POP, and the IP phones send echo to the far end.
