We have had both limited success and painful experiences with the SBX DECT phones. We have a customer with three DECT phones, and one of the phones keeps experiencing chronic satatic. We have frogged the handsets and the base, with no success. Has anbyone had any luck troubleshooting DECT phone issues?

Hi, we are also experiencing this chronic static noise on all the DECT phones installed. Vertical tech support have asked me to test the phones in another system on a different location. Are the base advisable to be side-by-side in a closet.

There's a limitation on where I can install the base units as implementation is on a warehouse office not to mention the limited availability of the in-house wiring as the contractor cuts almost all the in-house cabling.

Need help.
Thanks.

By the way, our client got 4 DECT phones in all and 3 24-button phones.

Thanks.

I installed three on an STSe system next to each other. I experienced multiple problems. Separated the bases by 25 ft. That seem to do the trick. In for 1.5 years. Haven't had a problem. Hope that helps.

My DECT phone experience is only with single phones so I think Ted is on to something. An Engenius install I did once with multiple bases caused a serious noise issue and reduced range until I separated them.

Thanks Ted and Dave...although I am not sure yet on how I can separate the base's as we have very limited in-house cabling that work.

By the way, I am still to test the 2 DECT phones I pulled-out yesterday. The status of the 2 phones left at our client: the DECT phone where the base is in the closet together with the KSU is still making that noise and the DECT user can't hear me when I tried calling. The other DECT phone where the base is installed afar from the KSU is working fine.

Again, not sure if having the DECT base next to the KSU is a good idea.

I will let you know the result of testing the 2 other DECT phones here in our office.

Thanks again.

The 2 DECT phones works perfectly fine here in our office...although everything works fine with our initial client install until after about one month were they noticed the noise and becomes louder until they can't barely understand the other party.

I will see on how I can separate the base units.
Thanks.

I have separated all the 3 base stations away from each other...and the problem persists after approximately 1 week after resetting the base and the cordless phone by removing its battery.

I haven't returned the 4th dect phone for isolation purposes.

I just tried unplugging the whole KSU including all the base stations and took-out all the batteries of all the 3 dect phones last night and will see from here.

Need help.
Thanks.

I am awaiting your solution with baited breath...

Have had similar problems. Comes down to they're cheap (certainly not in price), and your success with them is hit or miss IMO. The older ones we have work pretty good, new ones we get are probably 50/50. I don't like the V10k or the DX series cordless' either and I get tired of customers saying well I have this phone I bought from wal-mart and it works from here to there with no issue. It's embarrassing and they're correct. If only the wal-mart ones could have line appearance .

Same thing here. We have had a lot of problems with the DECT phones. Batteries quit holding a charge... static... etc, etc.

I think in the documentation for the DECT phones it says multiple bases must be at least 6 ft apart. If its not in the Vertical docs I know its in the Avaya docs because its the same DECT phone on both systems. I have noticed on the Avaya side...just because we put them in more often..that we do have to replace the batteries alot....

Turned-out that the 4th DECT phone in our office did the same static/humming noise. Called Vertical and they've asked for the approximate purchase date of the DECT phones...tech support immediately sent us 4 new base station ckt-boards... which I installed around mid-last week. And as soon as I replaced all the ckt-boards of all the base stations, the static/humming noise all gone. We are still doing further observation though...hopefully it fixes the noise permanently. I have asked tech-support if there's any known issues with the ckt-boards or anything related to the noise...got no clear response. All 3 base stations are all more than 20 feet away and the 4th DECT phone is still in our office so I can also observe accordingly.

Thanks for updating. I hope that does the trick. I don't like it but sometimes I have to sell one of the Dect phones and I would like it to work.

sonny I had the same thing. They advanced replace and problems went away. Tech said they put in updated chip set. Must have been a bad bunch because some of mine from 1 year and a half ago are fine. They even followed up with a phone call to make sure everything was ok.

When they work they are great with range and sound

that's good news Jim! I'm also suspecting they have a batch that has this problem but vertical tech support didn't gave me a clear and straight answer...they just said they will immediately ship-out a new set of ckt-boards. it's been a couple of weeks now and hopefully everything's fine so we can collect their remaining balance. yes, we've had about 3 DECT phones installed like a year or so and didn't encounter any problem and all works well.

thanks.

Bad news on my side Jim! Exactly one month after I replaced the circuit boards...the 2 DECT phones out of 4 have started to do the same humming noise. I haven't called Vertical yet as their Tech support is now closed. How about your case...was the humming noise totally gone after replacing the ckt board? Thanks. sonny

Yes. It has been fine. (knock on wood)

i just received the 4 new circuit boards from Vertical. hope this is the last time i'm replacing it. sonny

i initially didn't replace the other 2 ckt boards that were working fine but i had to replace it anyway as advised by Vertical tech support and it's also because i have to send back the set of 4. so far so good...//alvin
