now I wan't to try receiving faxes.
I adjusted my SPA3102 with the HowTo from 3CX to work as an ATA device on the fax extension with 3CX. I can dail numbers and the other fax machine is answering and I can receive calls from other fax machines. But no fax will be transmitted.
Where should I start to search? I can hear the other fax machine and it seems the machines are talking with each other but then my machine is aborting with failure "No right answer". No fax will be transmittet by receiving or sending.
The How To's from 3CX can be found here:
Has anyone the same or similar problems?
Thx in forward
