Outgoing FAX Compatilibility with VOIPO

[nomenclator]

OK, today I tried turning off Error Correction on my modem, and the fax appeared to have gone through.

In Windows XP, I did Control Panel > phone and modem > modem tab > [modem highlighted] > Properties button > Advanced tab > Change Default Preferences button > data protocol dropdown box select “disabled.” Normally the protocol selected in this dropdown box would be "standard EC," I think that must stand for "standard Error Correction." If Error Correction is set to "disabled," in the next dropdown box, "compression," the value is automatically changed from "enabled" to "disabled;" you can confirm this by closing the window and re-opening it.

As I mentioned in my previous message, I noticed before that there is a beep heard during the call - but with EC disabled, the beep stops playing after the modems "align," synchronize. There is another word but I still can't remember it.

Note that whether EC can be left on or needs to be turned off may depend on the the kind of fax device or modem on the other end, or how it is configured.

Hello Everyone,

When dealing with voip services it is hit or miss when it comes to transmission type devices, alarm panels,fax machines, etc. There is a big difference between digital and analog communication. To be safe dont use voip for these types of devices because it may be working now but when you really need it there may be a issue, damage, or loss. Companies know of the issues and some have found ways on their end to correct some of the issues to make it appear to work good one of those is vontage, but when their fix fails you will be back in the same boat as everyone else. Because of those companies correcting or managing the transmission people believe that voip can be used for these devices. If you read the manuals for the equipment including alarm panels the manufactures have updated their manuals to have clauses when using voip services.
Alarm panels have a upgrade now to communicate internet, or cellular and there are fax to email services of which VOIPo offers.
