On any of the 79x5 instruments, it appears if you have your headset hooked up to the headset port on the back of the instrument AND the handset plugged in to its port on the back as well- that whenever you have an active call using the headset that it also enables the handset for some reason and you get an "echo" because you are hearing the other output. There is no known setting that I am aware of that will "fix" this issue.
Our suggested workaround for the time being is- you can hook up the headset where you plug the handset into the headset base unit instead of the port on the back. The only difference is they will have to plug the cord from the headset base to the headset port on the back of the instrument (not the handset port). This will eliminate the echo issue. However, it will also disable the use of the handset entirely.
I guess their intention for a wireless headset is better used when someone is not sitting right by their phone and has some distance so that the "echo" is unnoticed...I guess. Any other ideas?
I've already tried that and should've included that information in my original post...I have a 7975 using 8.5.3S.
I'll search for that BugID, but your reply would've been more helpful if you referenced it. I would recommend you consider doing that before you respond to a post. I was unaware there were restrictions to posting, could you point me to this as well?
That appears to be the exact issue I'm facing, thanks for the reference link.
I have Load File SCCP75.8-5-3S running on my 7975 and am still experiencing the dual audio. I see where the Boot Load ID is tnp75.8-3-1-21a.bin ...is this what I need to update? If so, then I am unaware of how to do this. I've already downloaded the cmterm-7975-sccp.8-5-3.cop.sgn, uploaded it to my TFTP, and specified the load under Device Defaults- which is how I'm at the Load File listed above. If that doesn't change the Boot Load ID information, then I'm not sure how.
It appears the issue has been resolved. We recently upgraded to UCM 7.1(3b) [22.214.171.124000-1] in hopes of clearing up a couple other issues we were having. This release has 8.5.2SR1 as the default firmware for the 7975s and we experienced the same problem with the dual audio. I upgraded to 8.5.3 at this time and only then was this where the problem appeared to go away.
