5050 fax system using analog line to Arris digital modem that is supposed to convert analog signal to digital to work on clients VOIP phone system. After dropping baude rate, turning ECM TX and RX off, etc. fax is working but very, very slow. First test: connected fax to 5050 with fax switch and sent 12 page set to 5050 took a little more than 3 minutes. Second test: 5050 from one office to another 5050 next door in another bldg and same 12 page packet took 10minutes 30 seconds Third test: faxed from off site fax to 5050 with same packet and fax took 10 minutes 23 seconds. Fourth test: both 5050's took 10 minutes 17 sec to send fax to my office 55 miles away. Bottom line: TX and RX on 5050's extremely slow. With client faxing 200 sets a day it ties up the machine and client gets busy inquiries from their contacts all day long. VOIP is Roadrunner and even after talking with them and having them tune their system, not much difference. Anyone have any ideas? Have considered fax to email, but it is a medical office dealing with HIPPA.

If you have to drop the baud rate like you mentioned at the very beginning of the post, how do you expect it to transmit faster? That is the speed limit right there.

In 1989 when Kyocera first joined in the fax game, the top baud rate was 9600 bps and under ideal conditions you could send a standard CCITT "Slerex" test page in 23 seconds. Real world it took more like 30-35 seconds per page. Now what you did was roll your communication standards back to this age in order to compensate for lag-time involved with digitizing audio information into data packets, compressing that digital information using a "lossy" method (all real-time digitizing has to use a method of compression which throws out data in order to make the packets smaller in size), then reconstruct on the other end into an analog audio signal.

What you have is the catch-22 of faxing. You can do it fast and reliable (with a dedicated analog POTS line) for a higher cost, or unreliably and slower with a cheap digital line option. You trade one off for the the other, and really cannot have both.

Well, high-priced and unreliable is also an option, but I believe I made my point.

Just put in some brother, other fax and i am sure it will work better than the kyocera fax

Ok, they have a VOIP and probably internet, why the HELL are they forcing FAXING. Scan to EMail that is what digital is all about!!!

Faxing is old technology and requires an analog line to work properly.

Yes, I have seen cheap Brother faxes work faster than Kyocera on VOIP, but the modem is 14.4 or slower and with no error correction. The funny thing is that when faxes come out looking like **** due to line errors, the customer does not complain about the cheap fax, it seems to be expected, but will they scream about the slow Kyocera, you bet.

My personal recommendation for customers going VOIP that have to have fax is to invest in a network fax server, or use a dedicated analog line for the fax. These are really the only options if your customer must have faxing.

All the testing for speed was done at 14,400 baude rate. Because of the haphazard signal, I dropped the baude to 9600 to insure they would get the fax as per their VOIP vendor. In 6 months they have done 15,000 faxes. It is a high volume fax situation and the principals there are having a difficult time understanding the parameters of their phone system vs. what they used to have. For 1 or 2 sheets it would be adequate, but for faxes containing EKG reports and other medical reports the sheer amount of info on the page is slowing it down as well. The fax server is what is needed, but the client feels like we should be able to make this work regardless. You've been there I am sure.

Whenever there is a fax issue and the customer does not believe what I tell them about needing a dedicated analog phone line for reliable faxing, I give them the number for Kyocera User Support who will tell them the same thing. Any other configuration is smoke and mirrors and is not supported by Kyocera.
