I have an Obi100 that works fine, so I bought a 202 and a WiFi adaptor to provide a phone line for a fax machine (it's actually a Canon Multifunction, but whatever).
I have a VTech cordless phone plugged into the proper port on the MFC.
I have a fax to send.
I try sending it using the Canon - it dials, but there is no ENQ/NAK and the call fails, so it tries again - and fails again. It prints an error page which says "Busy/No Dial Tone".
I mentioned the VTech - I can dial that same fax number using that VTech handset and I get the fax tone.
What am I doing wrong? (The Firmware is current on the 202).
