I have a client that had a NEC DSX 80 installed in December of 2007. Seems that when they are on the speakerphone on a CO line (all 13 phones) the speakerphone is choppy, choppy to the point they can't use it. If an internal call is made via the intercom and voice announce all is fine.

I though I remembered reading that this was a software bug, is this true?

Thanks

What software version ?

You need to be on site and test yourself.
If it is choppy, trying hitting the Mute key.
The phones could be clipping.

You may try adjustment of loop length.
Look at Lines/Config settings (program 3102)
Adjust loop length (I would try AUTOMATIC first )
Depends on your Version.
You may also look at Transmit/Receive gain same program.

I only had (1) issue with this problem and found
background noise in office was the source of problem, causing the VOX circuit to chop audio.

I have adjusted the transmit/receive gain to fix the same sort of problem!I think STS E has the fix!

Unless there is sticky notes over the mic!How many out there has ran into that?I did last week,I felt sorry for the customer But had to chuckle a bit!

No sticky notes
I had the customer go on speakerphone while I was in the phone with him and there appeared to be no background noise, will be on site tomorrow.

I was joking!But one of our techs went on site with a customer that had an IPKII with the same problem and no joke every phone had the desi lable covering the mic!!!He found it quick thank goodness otherwise that would have been a fun troubleshooting session!Im glad we didnt do the install!!

Transmit and receive game was the gig.

Thanks

Have the same problem what T/R setting did you use?

His settings may vary.
You have to go on site and adjust to the co line
you are working with.

That may not be your answer.

ok thx i will go onsite tomorrow and try adjusting per line. Are there any guidelines or a starting point to figure out what the setting should be?
