Re: [hylafax-users] What is your percentage of hard failures

[Andrew Taylor <ataylor@xxxxxxxxxx>]

We have 18 modems here in the US handling about 4000 fax jobs a day with 
 a 35% average failure rate.
We also run HylaFAX in 12 overseas locations with single modem setups 
and see from 30-50% failure rate.
I know of 1 fax machine that will not work with our MultiTechs, a 
Lexmark T520 printer/modem but I am sure there are others.
The most common problems are bad fax numbers or extremely busy numbers.
Regards,
Andrew Taylor
