I have a site where the customer bought the system from Amazon and we installed it.

Intercom or outside calls are very choppy on speakerphone but not handset, sounds like a VOIP phone without enough bandwidth.

New control unit shows the same problem, Any Ideas?

Earlier produced X-16 phone shows the same problem.

if it sounds fine on the handset but bad on speakerphone it has to be bad equipment ...... suggest to them they call Amazon

good luck with that!

Are you sure there just isn't background noise and the speaker is turning off because it has voice detection? This happens with my Partner phones if you leave the microphone on with music or a video playing nearby.

I was onsite and made both intercom handset to intercom speakerphone and outside call to intercom speakerphone.

Both were totally choppy just as if you had a VOIP phone but insufficient bandwidth.

I tried with a new phone of earlier manufacture and it was the same.

X-Blue sent out another KSU and it was the identical problem.

There is standard 4 pair wire in short runs, maybe 100 feet at most.

I'm prety good at trouble shooting but this has me baffled.

I've now picked up another whole system X-Blue sent me and will test that this morning at my place before going out there.

X-Blue support on this has been wonderful but they are as stumped as I am on this and I just thought maybe someone had the same problem.

Thanks, Bracha

I'll bet it's not the system and they'll all work fine at your place.

Something in their office or the way they're using them is causing it.

Are you sure you are not using VOIP lines, supplied by someone. I would check that.

That wouldn't apply for the intercom calls...

Ambient room noise? what happens to the speaker audio if you activate mute?

Finally solved today.

ONE phone was the culprit. I replaced the phone at 301 and the choppy voice was gone from ALL the phones.

To test, I replaced the original phone at 301 and ALL phones were choppy. Intercom as well as outside calls - any speakerphone call.

Once 301 was replaced (no we couldn't be confused, all their phones were platinum and the new phone was black) ALL phones had a working speakerphone.

Previously I had taken a platinum phone out there but swapped it at 303, not 301 and there was no difference, it was garbled.

So if you come up with a system where ALL the speakerphones work very choppy, you have one bad phone somewhere and can quickly narrow it down by unplugging one port at a time.

This was a stumper, even for me, but now we know that one defective X-16 phone can scrw up the whole system. Fortunately that is the first defective X-16 I've seen.


Thanks for your input, Bracha

Thanks for the info!
