  • Q:

    Is this machine compatible with VOIP?
    Asked on 3/26/2015 by Collier from FRanklin, TN

    1 answer

    • A:

      You can use it but it will take a bit of tech. know how. Here is the info for how to get this to work with VOIP.

      Using standard fax machines over a VoIP can be problematic. The reason for this that VoIP’s audio digitization processes are optimized for human speech, not the signals used by analog fax machines.

      This fax machine is just a standard machine, it isn’t optimized to be used with a VoIP system however it can still work. Some adjusting of the settings need to be done such as disabling the ECM (error corrective mode). To do this on this specific fax machine they would need to;

      - Press Menu then press either the right or left arrow button until you display Advance Settings.
      - Press Set
      - Press Start/Copy to access the settings under TX settings.
      - Press either the right or left arrow until you see ECM setting (code #68).
      - Select the ECM Selection Mode=OFF by press the + or – until the desired setting is set.

      Next they will need to set the machine to “Overseas Mode”, to do this;

      - Press Menu, then press either the right or left arrow button until you display Advance Settings.
      - Press Set.
      - Press Start/Copy to access the settings under TX settings.
      - Press either the right or left arrow until you see Overseas Mode (code #23).
      - Select the Overseas Mode=NEXT FAX by pressing + or – until this setting is enabled.

      When using a standard fax machine with VoIP you normally want to reduce the BAUD rate to 9600. Unfortunately, Panasonic fax machines do not allow you to do this. Brother machines do, so they may be the better choice.

      The customer will also want to make sure the fax line’s VoIP connection be set to a G.711 codec (non-compressed) if possible. They will also want to set their resolution on the fax machine to standard instead of high or extra fine. The higher the resolution, the more data needs to be transferred over, the more likely a failure can happen.

Cartridge Comparison Guide
  • Cartridge Types
  • Ink & Toner Basics
  • Number of Pages & Shelf Life
Cartridge Type
Genuine or OEM (Original) Cartridges Remanufactured Cartridges Compatible Cartridges
Description OEM stands for original equipment manufacturer, meaning the cartridge was made by the same company that made your printer. Original brand cartridges are very reliable and sometimes the only option if your printer is new to market or uncommon. Remanufactured ink is a genuine brand cartridge that has gone through one cycle of use. After use, the cartridge is recycled, acquired by a remanufacturing facility and put through a rigorous professional refurbishing process. During the refurbishing process the cartridge is disassembled, thoroughly cleaned and tested for quality. It's then carefully refilled, tested again and brought back to life. Buying remanufactured prevents one less cartridge from ending up in a landfill. A compatible cartridge is a brand new ink cartridge built by a manufacturer other than your printer. It's like buying the generic version of the genuine brand. Most are uniquely designed to differentiate from genuine cartridges. Despite any structural difference you may notice, the cartridge will still fit in your machine and print a full yield, just like the original brand.
Price Factors Many printer manufacturers follow the razor-and-blades business model which may result in higher priced genuine cartridges. Remanufactured ink is much cheaper than the original brand ink. It's far more cost effective to refurbish a previously used cartridge than create a new OEM from scratch. Compatible ink is much cheaper than the original brand. Compatible suppliers don't have to worry about the additional costs that hinder OEMs like new printers or firmware, which lets them keep prices low.
Quality Original cartridges work extremely well and are covered under a warranty by the printer manufacturer High quality remanufactured ink will match the quality of the original, but not all remanufactured ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results. High quality compatible ink will match the quality of the original, but not all compatible ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results.
What's the difference between ink and toner cartridges?
Ink Cartridges Toner Cartridges
Printer Type Work with inkjet printers Work with laser printers
Material Liquid ink Dry powder
How it works Inkjet printers use a series of nozzles that spray tiny drops of ink directly on the print suface Laser toner printers use static electricity and heat to bond dry toner powder to a page
Commonly used by Casual home users, small business and photographers Large businesses and schools
Number of Pages You Can Print A cartridge's page yield is the estimated number of pages you can print. Page yield is based on 5% page coverage. This means that the quoted page yield is based upon printed pages where only 5% of the page has been imprinted with ink. For example, a short memo has approximately 5% coverage. If you have a cartridge that has a yield of 500 pages, it can print 500 pages of that short memo. If you are printing letters, photos or graphics, your coverage will vary greatly and your page yield will drop significantly.
Cartridge Warranty and Shelf Life Most ink and toner cartridges include a warranty or "best by" date on their box. Remanufactured and compatible ink cartridges can last 12-18 months unopened, and toner cartridges can last up to 3 years.
Cartridge Care and Storage Only open a cartridge when you need it. Opened cartridges will eventually dry out, especially if the protective tape or clip has been removed. If you have an open ink cartridge around and would like to try and prevent it from drying out, place it nozzle side up in a plastic airtight tub. If your cartridge came with protective tape or a clip reapply both before storing. Place a damp cloth or paper towel in the tub, next to the cartridge and keep it stored in a cool, dark place.
