Problem with FAX and Firebox (Shamrock Fax Software)

acon59

The following info:

When you want to send a fax, you always get the message.
"Remote station is not a fax". (Gegenstelle ist kein Fax)
Both remote stations negotiate, one side says it is a fax, sends something back but nothing comes back to the customer.

If you call the customer directly, you only get a connection to the paper fax connected with the Fritzbox, but not to the Lancapi.

Hi @acon59
I would suspect based on the type of message you're getting that this might be a problem with the service you're using vice the firewall. If the firewall were blocking the connection, it'd likely completely fail. Since you're getting a message saying something about the remote end, communication is working. The firewall doesn't specifically know how to change that message -- unless something like a 404 is being interpreted as such.

If you haven't done so already, I'd suggest reaching out to the support team that maintains that product.

Anything obvious in Traffic Monitor when someone tries to send a FAX?
