Hi All.
Our client is running a 3cx server on an windows server 2003 machine. It is PSTN only no VoIP.
All has been running fine for many months however recently they have been complaining that sometimes when they answer a call or make a call they can hear fax tones.
I too heard the noise when I dialled in - when the auto attendant answers a fax noise kicked-in.
Its not all the time, and sometimes if they hang up and dial again they can hear the same noise.
Had anyone experienced this at all?
Thay tell me there is no fax machine on the line, no credit card system and I have stopped the 3cx fax service just in case.
Any help would be appreciated.
Thank you
Regards
Andy
