[Ash91]

Hi,

I have an analog fax machine and i want to connect it to 3CX phone system. I used obi110 to route the phone calls to 3CX and its working perfectly. Now if i want to connect the fax machine as well to 3cx will i need a FXO port or FXS port in Obi? If i use FXO will i recieve fax or should i use FXS? Thanks in advance

Try reading this and see if you understand the difference:

Also, what may speed things up is if you have an incoming line (VoIP or landline) already set up on your OBi110, you can always plug your analog fax machine into the connector that has the word phone with the arrow pointing and see if it works.
