Wireless hell

I have a customer, a very small physical therapy office that has been having trouble with their phones since they opened a year ago, they say. The initial issue was static, bad, and it was reported to Telco many times and they kept getting scheduled out 3 weeks so they finally switched to the cable company phone lines.
They have a cordless 2 line phone system that is daily dropping calls and the main thing is that they cannot be heard by callers, intermittently but often, on all sets. There is just the one corded base and 5 cordless handsets. 6.0 DECT.
They also, at the front where the AT&T phone base with the big antenna is, have a cordless printer, a Ubiquiti WAP, which is just a bridge from the one in the back that is plugged in to the router, a cordless headset. In the back, on the floor under a desk, they have another cordless phone with the 2 big antenna, a wireless printer, another Ubiquiti WAP, a wireless modem from Spectrum, a wireless Linksys router, and I think that is it. Then around the office there are 3 more cordless handsets just the remote kind.
They have changed telco providers and have changed the phone system 3 times. I loaned them a 2 line Panasonic corded/cordless 2 line system for a week, same issues.
SO...my question is, do all of these frequencies cause problems? I don't see how they wouldn't but honestly don't really understand all of it. I am a wiring person and I know that copper is more reliable than air and I don't know why anyone would run an entire office with everything wireless.
I am recommending trashing the Sync AT&T phones they just paid $500 for and getting everything wired. But they say they do not have the budget for it. I say they will spend the same amount on service calls from me, the IT guy, and telco trying to troubleshoot. Again, the issues are mostly that callers have to call 2 or 3 times before they can hear the P.T. employees picking up the calls.
 
How many wireless AP/Routers do they have? =)
You say it's a small office, shouldn't it be enough with one AP and a DECT base to cover it all?

Are the trunks wired?

5 sets on 1 DECT base is probably at the top end of what it can handle. Try dropping that down to 3 and see if the issue remains. If that helps then adding a second base and getting the other sets registered to that would be a lot less cost than trashing everything and starting new.
 
Have you called the SMB Synj/Snynapse AT&T help line?
Looked at any logs or alarm codes?
How high is the base? any obstruction to it?
Since it does not use the network or have SIP lines it is either a simple fix or defective therefore calling the help line in this case is a must.

I would try turning off the wireless printers temporarily, then test. That seems to be the only device that has not been replaced, or suspected.
 
Janni78, they have one AP plugged directly in to the Spectrum modem in the back and the other one is just a wireless bridge (no cabling) for the front reception area and the front part of the office for iPads and laptops. I guess 1 was not doing the job, so the IT guy added a 2nd one.
Spectrum ran cat5e from their modem to the reception desk and put the jacks up there for the base.

Wanebo, a 2nd base might be a good idea, not sure if they will spend the $$. I can check. I will remove a couple remotes and see if that helps.

Curlycord, what cracks me up is when you look at their troubleshooting section in the user guides, all of the potential issues the phones are having are there. THEY KNOW their product is a piece of crap!
No obstructions, you can only have the base so high! It has to be on the desk! I would think it was a defective but it is the 3rd system with the same issues. I blame it on Spectrum, but we checked all that out yesterday and they could find no issues at all on the telco side.
 
What exact type of line is this? isn't Spectrum a cable company down there?
That would say it's SIP but converted to analog.

And same question for the last carriers line types.

I would be looking at wireless issues. All these devices are running on 2.4 Ghz.

Yes, Spectrum is the cable company, not a real phone company, as I like to say, haha.

Previously it was Hawaiian Telcom, the real phone company.


allworxguy, can you give me a little more info on the 2.4Ghz. spectrum, I really am pretty uneducated about all of these frequencies. Why do you say it could be a problem, and would it be worth changing the frequency on those Ubiquitis? The IT guy said that can be done.
 
It was just a corded base with a cordless handset and 3 add'l cordless remotes. I guess I can call it a corded base since that is what needed to be plugged into a jack, but it was also a 2 line cordless handset.
 
allworxguy mentions conflict with 2.4 but DECT is 1.9 which does not interfere with WiFi.

Wanebo might be on the right path, maybe the handsets are interfering with each other and to try only one phone for a day.



Just curious, if the place is so small why are they using cordless? can they massage and hold a phone at the same time?

curlycord---why does ANYONE use wireless?? Copper is more reliable than air, as I always say.
i am going to go run some wires tomorrow to eliminate one of the Ubiquitis and a printer, but I didn't think to check for Loop Current issues. I will test it first. I have had some really, really random and hard to troubleshoot problems in the past with consumer equipment that turned out to be because of high loop current. I used Sandman's tester and regulators and it fixed the problems on a couple of jobs. These jobs were both within a block of the C.O. I also had the same issue at my own office, frying fax splitters(the Stick, Comshare, etc.). I went through 3 of them before I figured out it was super high loop current because the C.O. was at the end of my street. I used one of Sandman's regulators and never had another problem for the 8 years I lived there.
These issues were always with Telco lines, not cable company lines. I suppose they can have the same issues?? High or Low loop current?
This particular job is a block away from the Telco C.O., but these are cable lines (Spectrum).
I gotta get this thing fixed. They are really making customers mad because the line rings, the callers can't hear them pick up and they have to call back 3 or 4 times before it works correctly. Every day, many times.
 
I am embarrassed to say!! The customer got a replacement base from the manufacturer and it fixed everything!! What a pain in the $%^#.
Simplest thing. So many random things going on there.
 
I've been doing this for a while, and in addition to my current life, in a previous life I was putting up buildings and remodeling wings for my company. How much do you know about the construction of the building they are in? Many medical facilities, depending on area fire codes, building codes and other relevant issues are set up with steel studs rather than wooden studs like a house, and in some cases can also have a lot of steel in the roof supports and sometimes even a steel roof. What I have found over the years, with "consumer" cordless phones, cellular phones, and other wireless devices is the building acts like a giant faraday cage and all those signals are having trouble passing through the walls, and there is also a lot of signals bouncing around and becoming distorted and causing interference (I can't remember the buzzword right now). That can cause a lot of call quality issues like dropped calls and range issues, but static is kind of weird in a digital system - it's usually either getting siganl or not. I could see a lot of issues with voice distortion, missing words, jitter, etc (like Max Headroom... I just dated myself!)... If the building construction is causing problems you may end up switchng to a wired system like a small Panasonic key system you might be able to set up for less than $1500.

Thank you for the suggestions Don. This is an old cinder block building, but it does have a corrugated steel roof, now that you mention it. Yes, wired is always better. As I always say "Copper is more Reliable than Air!
 
The other thing to consider is if the building has multiple floors with concrete floors, because it is very likely (unless they used spancrete, and I doubt it if you used the word "old" that the floors are loaded with re-bar. The concrete is bad enough, but the re-bar doesn't help, plus if it's old enough (sections of our hospital are from 1947 and 1965) the walls may be made out of "chicken wire and plaster" - you will know if you ever tried to cut in boxes. There are some cordless phones you can get that have ungodly range made by engenius - I believe the model may be duraphone, that support booseted antennas and like in thew 900 Mhz range. 900 will penetrate a lot of crap better than the newer phones.

donb01...in case you missed this line the issue is resolved:
"The customer got a replacement base from the manufacturer and it fixed everything!!"

I think most of today's wireless products can deal with buildings much better than in the past.
