I am having issue where users report some echo on the IP phones every now and then that lasts the whole call. The echo they hear is their voice back on the IP Phone. The outside party does not hear echo.
The T1 PRI controller is clean, no errors and the router network-clock is set to use the PRI. We have tried setting the network-clock to defaults to use backplane and that had no change.
Yes, we have and with anything other then the defaults the users say it is worse. so we are back to the defaults and no reported issues for 5+ days again. We were good for 3-4 days before, then had one day with the issue and now clear for past 5 so maybe they have some on/off issue with the PRi circuit causing some issue.
The IOS is 12.4(6)XE2 and DSPware is 9.2.0 in that
I am thinking of trying to get new phoneloads on there. Can I go to latest 12.4.11T2 from 12.4(6)XE2 without issues or losing anything that is in this XE2?
Since the echo is heard on the IP phone side it is the PRI echo canceller that is not able to cope with the reflected signal from the far end. Phone loads should not have any effect on this.
I would suspect that a specific far end phone system is causing you grief. Of course you can't fix someone elses phone, but it is very useful to find a number you can call that results in echo, allowing you to make changes and test.
