Improving Dial Up in the age of VOIP?

[Red_Viper_Martell]

Ok, this is a long shot, but if you guys don't know, who does, eh?

I need to use a dial up modem to submit documents to a certain server. From what I understand, my modem makes its nostalgia inducing screech into the phone line but along the way everything gets converted to some variant on VOIP by the provider (as all long distance works today) and the little packets go on their merry way. On the receiving end there must be some device for reversing the process at which point the server receives its input.

That would be fine, except the VOIP interface is lossy and the the communication with the server only goes through about one time in ten. Nine times in ten, loss of information results in the server rejecting the upload since the file fails simple checksum verification.

My question to you fine people is: do you know of a better way to do this? I know there are ways to email a fax machine, for example, and to receive a fax in my email box. Can I send a digital signal, with all the hallmarks of modern loss prevention, to the servers dial up modem? The server is owned and operated by the government and I have zero influence on what they choose to use for this interface...

Thanks for any info!

If the lines are actually the old analog phones lines then it does get converted to digital but it is not VoIP it is highly likely it is still using the older methods. Now if you have a analog line off say a digital pbx then that could be VoIP it depends on how it is configured.

You can pass fax over VoIP but it must be set to use a non compressed codec. In most cases it uses g711 just like the older digital telco uses.

We put modem lines in on many of our remote routers to give us out of band access when the main network fails. When we start to get lots of errors generally the telco needs to go out and check the line. Your problem could be simply that you have poor line quality.

You are pilling stuff here. Even though you are faxing "pictures" this is the same facility used to transferring data as well, and no bits can be lost, the transmission facility does not know if you are transmitting picture which maybe compressed lossy. Lossy/no lossy is really the control of the communicating clients and not the call of the carrier.

Communicating with entities with outdated facility... you maybe able to better slow dialup if such facility has the ability for you to buy a dedicated telecomm link to it directly from your office. You should be a pretty important client and/or willing to defray the cost of the setup for equipment on both ends.
