Re: [hylafax-users] V.21 signal reception timeout +FCERROR

["dev.malst" <dev.malst@xxxxxxxxxxxx>]

Some kind of VoIP, not a really complete VoIP network, but a provider converting telephone (analog) communications to digital signals inside a cisco router.

The strange thing is that we have problems almost exclusively by fax of a given zone (prefix 050….). From many other fax we receive with a percentage of error very low.

 

Some clarifications to be more possible self-employed in the log analysis:

 

1)    Nov 29 09:37:54.85: [ 3155]: --> [10:NO CARRIER]

-          You say 10 seconds. In the log, the numbers before colon are seconds ?

-          Arrow --> means modem (DCE) to hylafax (DTE) communications ? and <-- means hylafax (DTE) to modem (DCE) communication ?

 

2)    Can a VoIP T.38 line allow reception well at some time and wrong at other time ? congestion or something like that ?

 

3)    Can a VoIP T.38 line allow reception well all times from specific remote fax and produce wrong reception for some other remote fax machine ? this is our situation. Perhaps best remote fax machine can resolve this issue ?

 

4)    Can we set hylafax to invalidate all fax communication if REJECT by Page Quality arises ? so remote fax return an error to operator and operator know to resend fax ?

 

5)    What’s this “MODEM <Empty line>”

6)    What’s this strange character instead of “2:<modem response command like OK or CONNECT or other>” ? I hope will be readable, if not it’s seams a Unicode 2 byte character.
