Hi, I have a few questions regarding Echo Cancellation in vISDN.
a) When I run "visdn_configurator", i noticed the visdn_ec is loaded. Does it mean that Echo Cancellation is activated for vISDN ? b) With visdn_ec loaded, I tested the following scenario : Phone A <------> Asterisk IP PBX <---ISDN ---> Phone B. I called Phone A using Phone B. The call at Phone A is answered by turning on the speaker at Phone A. This is to create echo back to Phone B. I realized that I can hear my voice after a slight delay, i.e. echo when i spoke into Phone B. Does anyone have any idea why I am still getting echo when I have enabled Echo Cancellation in vISDN ? Thank you. Regards, Kwang Mien _______________________________________________ Visdn-hackers mailing list [email protected] https://mailman.uli.it/mailman/listinfo/visdn-hackers
