I know these bridges are old and EOL, these bridges are in operation for last 4-5 years and never had any issues. But for almost a month, I am starting to experience ECHO issues over phone calls. It is very intermittent. I have restarted the bridges, upgraded the software version, but still no luck.
What would you advise, one reseller is suggesting to go for P300, but I am not sure if P300 will resolve any issues if there is interference. Is there way I can capture the logs.
