I've read numerous best practices posts, guides, etc. but am still struggling with resolving wireless audio issues at one of my smaller sites.
Some background:
- The site has (5) AP's - all 1142N's and a fast 10
- I've tried the newest firmware for the 7925g's (1.4.3SR1.2) as well as our current approved "standard" firmware - 1.4.2 but the users claim there is no noticeable improvement.
- The site runs off the same controller as other remote sites I manage - and none of them are complaining of any issues.
- I'm forcing the phones to run 5ghz and have disabled data rates 6 & 9mbps.
- I'm not able to reproduce the issue after several test calls to both internal and external phones, but the users insist the problem occurs with "about half" the phone calls" and even if they are standing still.
I have run the site survey tool on the 7925g and the only warnings it provides is that my beacon value is not 100 and that I don't have Spectrum management enabled/supported by the AP's. I'm seeing adequate AP coverage (signal levels greater than -67 from at least one AP at a given time). I'm not certain why the report is telling me my beacon value is 102 - I've double-checked in NCS and the controller and it is set @ 100 as recommended...
From what I've read - one way audio is usually due to power level mismatches between the devices and the AP's - however unless I'm missing something I believe I have DTPC enabled...
I do know the code I'm running on my controller(s) is outdated and am in the process of scheduling that - however as I said before this is the only site that is complaining of issues with the 7925g's and I have over 300 of them deployed at various locations. Any insight as to what I'm missing would be much appreciated.
I may just open a TAC case but wanted to post here first! Thank you.
