Alcatel Mobile 500 Echo Alcatel Mobile 500 Echo TeleBug27 (TechnicalUser) (OP) 15 Dec 16 09:06 Used on an OXO system, the Alcatel mobile 500 DECT is giving echo, both ways. The echo cancellation is ticked in the VOIP Properties of the OXO Is there a setting somewhere either on the DECT Phone, DECT station or the OXO System RE: Alcatel Mobile 500 Echo sto933 (TechnicalUser) 16 Dec 16 07:34 Which SW version? Do you have access to ALU's technical communications? Read TC1938 - there are a couple of labels enabling and managing echo suppressor parameters. RE: Alcatel Mobile 500 Echo intrigrant (Systems Engineer) 14 Jan 17 07:54 Check your network first as echo is always a network problem. Beside that VoIP is usually point to point and does not need any media resourses on the telecom switch so a setting change there won't improve the quality. Only Voip <> TDM calls can profit from the OXO settings.
