I am trying to setup Aficio MP C3300 IP-FAX function, however, it never got working.
my sip server is local, and other sip device is working well. it is on port 5060, however, I just noticed that Aficio MP C3300 is trying using 517xx port to register, there is no way to modify it.
I just got really annoying about this device, is there anybody have achieve using the ip-fax function?
