Microphone volume on CP-524SG

[Eivind Jonassen]

Hi,

I´ve gotten some complaints from a customer about the microphone on the CP524 handset, their customers have trouble hearing them from time to time. Is there any way to increase the "microphone volume" on this phone?

Thanks,

Eivind

David,

Could you please post the CLI config so that I can test with my customer?

Eivind,

The CLI David is referring to is voice port specific (input gain, output attenuation). The gain the Product Manager mentioned is a configuration parameter on the IP phone itself. You can connect via your browser to the IP phone and experiment with these values. I am in the process of creating a document to explain these steps in detail, but you might want to give it a shot by yourself.

Thanks,

Marcos

Marcos,

Any update on the document?

I am still working on it. I am trying to document a procedure that would allow you to update all phones at the same time, and not one by one. My document will look something like this:

Hi Eivind,

Sorry for the late reply.

The CLI configuration i did was as per Marcos post, it was Voice Port based, this honestly does not resolve much.

I think it is best we both wait and see what Marco has Planned and then take it from there, i know that you would be anxious to get something happening straight away, but you just need to hang in there.

What might be of interest to you is, try and log into the phone via a web browser and have a fiddle with it i know with the SPA range you can raise the gain levels of the phone, i will test it on the 524 series as i am sure they will be the same as the SPA range.

Make sure you click on Admin login (NO password required) that will reveal extra settings, then make sure you click on advanced if the link shows up for that, this will bring up the advanced settings tab and will allow you to make adjustments then.

Cheers,

David.

Hi Marcos,

I tried the steps in the document, actually it seems like the handset got a lower volume with this config. I tried to use -3 insted of 3 but the result was almost the same. We'll try to deplay som 7900 phones, and let you know about the results...

That is certainly very unexpected!!!!!

Let me know the results with a 7900 in place. Again, we are not seeing this issue with our CP-500's here. Maybe an RMA is the way to go here, but let's confirm that other phones work fine.

Thanks,

Marcos

Marcos,

I´ve now been able to test out a 7975 phone at this customer site. The sound quality is better. The customer also complained about the speaker on the 524 phone, this was also much better with the 7975 phone.

One thing I noticed on the last visit was that the aucustic in this office is not that good, I guess if I were to scream, I could here a small echo..., LOL. I don´t know if this could cause the voice quality performance  on the 524 phones.

We´ve also deployed another solution with 23 of the 524 phones, and there´s no complaint on the sound quality from this customer.

The customer also told me that they had given up on solving this issue, and instead focused on raising their voice when they are making phone calls.

I´ve spent alot of time troubleshooting this and are now at point where I´m at stand still.

Don´t know if you guys are able to do anymore on this issue?

Thanks,

Eivind

Hi Eivind,

at this point what you need to do is open a  TAC case and through them, raise a bug report. We have not seen this problem broadly, so it might be hard to identify and solve.

Hi

Anyone got update on this status ?

I also experience the same problem in one of my Installation site in Malaysia.

Advice customer to talk closely to the handset, end up customer laugh at me :-)

.

Marcos, to open a tac case is not a one day jobs, lots of questions need to answer before the real problem been taken care of.

I d been experience lots of problem to open a tac case, all because

1. New installation, and customer dont buy smartnet

2. Customer have smarnet, but as a patner we cant open on behalf of them

go to PDI is not possible, once you identify the box is in production then will reject the case.

Is there a way for us patners have a access to an immidiate help if we required one ?

All we need to do is identify our self as a registerd or certified partners then we can get an immidiate SOS help

[Marcos Hernandez]

Hi Yamin,

Without a support contract, your only option is these forums. For new sales, PDI is the way to go.

Thanks,

Marcos

Marcos,

I think I found the root to the problem. We just received the new SPA phones, and I see the handset is just like the ones on the 7900 series phones, except for the MWI indicator. The biggest change from the CP500 series phone is the microphone input on the handset, you can see that the design is better on these handsets compared to the CP500 series, I haven´t quite tested this yet but this should not be rocket sience to see that this is probably causing the issue. I´m going to try and get a "trade-in" on the CP500 to SPA phones.

BTW, great job on design and pricing on the new SPA phones, I think this is a huge lift for the SBCS portfolio. When are the phoneloads going to be in a stable release on the UC520? I see that UC540 has a stable 7.1 release where the phoneloads are included.

Thanks,

Eivind

Hi Eivind,

I am glad to hear that you see value in the new Phone family of products. Regarding the phone loads, there is a 7.1.1-ea software pack for UC520 available on the software download area.

Thanks,

Marcos
