Walkie Talkie effect when using speakerphone 6961

[Youssef Aoufi]

Hi all,

I am experiencing some voice quality problems when using the cisco 6961 speakerphone .

The quality is fine when we use handset, but when i switch to speakerphone i can't hear the other side till i stop talking , like a walkie -talkie.

I am using CUCM 8.5 , i did a phone upgrade from 9.0.3 to the latest 9.2.2.6 without success.

Any help will be much appreciated.

Kind regards

Hi Youssef,

This bug sounds quite similar and although it only mentions the 6921 I'm pretty sure is

what you are seeing/hearing;

When Speaker is enabled, low audio observed when both the parties speak

Symptom:Customer is experiencing intermittent audio issues with 6921 phone when Speaker on the phone is enabled. During the conversation, few words sound very low audio level. Everything works fine if they use the phone handset or use a different phone model. Conditions:Issue exists with all the calls made using the speaker button of the 6921 phone and appears for both internal and external calls. Workaround:NA

Hi Rob,

Thanks a lot for your answer.

We have the confirmation from Cisco TAC saying that the CSCtu09371  Bug is causing this malfunction.

Here is the TAC answer:

. I have confirmed bug CSCtu09371 should be fixed in firmware 9.3(1) which will be released at the end of May 2012.

Unfortunately, there is no workaround for this issue. In the meantime, maybe the users should avoid using the speakerphone feature.
