Greetings,
I'm trying to diagnose a very annoying problem and hoping someone here might have some insight.
Setup: Mitel 5000 5.0 SP2 with Mitel 8528 digital phones.
Problem: When using the speakerphone on these phones, after 10 minutes the echo cancellation stops working and the other party starts hearing an echo of themselves talking. The only way to stop the echo is to mute the microphone while the other party is talking.
My provider has looked and tried to adjust noise cancellation settings but it has not helped. I just discovered in the 6.0 R28 documentation that this is a known issue.
DPAR ID MN00484653 - 10 min to 1 hour sip trunk speakerphone call - after 10 minutes the outside party starts to hear echo.
Like I mentioned, we're not on 6.0 yet but it appears to at least have started in 5.0. I'm hoping to not have to go to analog lines + Polycoms for the rooms that are currently using the 8528 phones with the speakerphone. The echo cancellation works for 10 minutes, so it's just a matter of figuring out the software to keep it going after 10 minutes, right? Maybe Mitel has an upcoming fix, or there's some other way to get around this? Possibly fixing by reducing handset microphone gain (have not done this before)?

We found it on version 5 something

Glad to hear it's not just me. Did you have any luck solving the issue?

We open a ticket with Mitel, haven't heard the outcome. More a 3300 guy and someone else was handling it. Only happened when using sip in our case.

In case anyone else finds this thread, 6.0 build 29 has a fix for this problem.
