Hi

Anyone heard of Uniphone (Taiwan) telephone systems
We are the distributors in Australia and I would like to find others that work on these systems in other parts of the world.

All the best

Never heard of Uniphone do you have a web address for more info.

Hi Merritt

Thanks for your reply

www.uniphone.com.tw

According to them they are the top selling system in Taiwan out selling Tecom,Hybrex and Aristel.

Their systems are in most of the hospitals schools and police stations in Taiwan

I believe there is a distributor in the US, but haven't been able to find them.

I would like to share information with them.

The systems are really good, but the documentation is somewhat lacking, so I am rewriting most of it and translating from the Chinglish.

I have a PABX background since 1970 so that is helping a bit.

All the best

looks like Key system US

Hi

Thanks for this

Key system US sell Atlas phone systems

Atlas are just staring to appear in Australia, very cheap
Uniphone and I have nothing to do with them

I am writing from Malawi.I have come across the Uniphone Telephone Systems and there are a good number of then in Malawi especially the UDK type.

At the moment we supply the Uniphone UDF-series digital telephone systems in our country.They are durable systems and the digital handsets are really strong.

You have made a good choice!

Hi

check out our website www.phonepro.com.au

Uniphone systems are really good, very very reliable

They are a bit different thna others and the documentation is not so good but we are working on it.

maybe we can exchange some information?

All the best

Hi,

It's true the documentation is not good enough.It would be really tough for someone who has never worked on other systems before. However, the goodness is that Uniphone are very prompt in their technical assistance.

No problem, we can share information on these systems.

Good day.

Hi Greg

Our company is based in South Africa and we deal with the Uniphone product.

Hi Greg

www.metrixsupport.co.za

We have been distributing the ISDK Uniphone series 26 and 56 for about 3 years. Currently we are in the process of approving the UD2100 for use in South Africa.

Regards
Okster

HiOsker

You can email me directly at [email protected]

2100 is a nice machine, we have one running fawlessly with PRA and voicemail, and about to put one in a large hotel with property management system.

UD60 is also very nice, rack mountable 60 ports

Al the best

hello!
yup!!greg is right!u can relly on it!i am installer of Uniphone also here in Brunei and i have direct contact with enginners of uniphone taiwan.anything that i can help with regards to uniphone just email me.thanks!

Hi Greg,

We had a desiccation previously about Uniphone (they were very upset that we spoke with you)
Unfortunately for us in the U.S.A. they destroyed our business, our installers business and reputation.
They did not cooperate with us regarding the V.M; we offered them and very knowledgeable engineer to work for them on the V.M,
but the RD department manipulated the management because of “losing face” – they did not want to admit that they cannot solve the problem.
Meanwhile, our customers lost patient, returned systems, our main installer in Arizona had sell his business and move to another state because
of it.
Big aggravation for us, they probably selling good all over without the VM so why to bother with the U.S.A market.
We really feel lousy because we helped them to develop and test not only the VM also advanced key features on their phones, alerted them on any new features in the market.
but they thanked us with smile and mountain of repeating excuses.
Few years and countless hours of work went down the drain
We send them damage units took them over year and a half to return them back to us they credit us the VM but we setting with systems and parts
that we cannot sell without a internal VM and after over year and a half the market is flooded with systems more advanced and user friendly
so now we think on creative ideas how to dispose of this systems we regret that they not made from very soft paper ha ha ha.

If this Uniphone was a US company we would sue them on damages and losses in a hart bit.

Just decided to let you know in case you get any inquiries for or about Uniphone and VM.

Wishing you all the best happy New Year

Hi Dubi

We only had one failure with the inbuilt voicemail, but we fixed it by defalting.
Uniphone admitted they have problems with the voicemail, but they are not the first manufacturer to do so.

A new voicemail card is under trial in Taiwan now.

In the meantime we use the Yosin external voicemail, it integrated perfectly, and we have not had any problems.

We have about 300 Uniphone systems running in Australia now, some for 3 years, with no major faults.

All the best

Hi,

This is to inform everybody that the UD-60 can now be expanded to 82 ports.You will need to replace the CPU and the power supply to upgrade the old system.The new CPU has one port for two digital key phones and then you will be able to use all the ten slots without any restrictions.There is also a new 8-port trunk card.

I have a problem with a UD-F 1016 power supply.What happened is the 3A fuse (close to the battery jack)on the board was found blown,capacitor C23 was also found blown.On testing the power board I found that one MOSFET transistor IRF540N,one transistor C1815 and one IC UC3843B were found to have been affected . With this set-up the red LED on the board was just blinking. The voltages on the ouput jack were as follows:
VEE=27V
-5V =0V
+5V =0V

After I changed the suspect components,the following were the voltages

VEE=33V
-5V =-4.9V-OK!
+5V =+10.8V instead of +5V
These voltages were tested with the power supply not connected to the mother-board for fear of damaging the mother board.


Now what should I do to get the correct voltages and what is the correct voltage for VEE.

I am relying on you friends to get the solution.Sending the power supply to the manufacturer is not the option at the moment.

Dear All,

I would like to inform you that I have repaired the power supply. Several components were found damaged and I had to change them. These components included MOSFETs(IRF540,2SK2717, shunt regulators(TL431),bipolar transistors(2SC1815), optocouplers(PC817),18V Zener Diodes,capacitors, and the high performance current mode PWM controller ICs (UC3843B).
I was lucky to source all the components locally from the shops and scrap electronic boards.I am saying I was lucky considering the part of the world where I am.

Thanks to Uniphone for sending me the circuit diagrams.From now onwards I will be able to repair all Uniphone power boards should a fault develop.

After repair the voltages are as follows:
VEE =27.6V
-5V =-4.90V
+5V =+4.95V

hi
Greg
i am writing from Ethiopia we deal with uniphone for the last 8 year.they are realy durable.

haile.
