I have customer who decided to downsize from seperate phone and fax lines at home, to a single phone line with faxability. They were able to keep their original phone and fax numbers, but when I was called in, I found that when their fax number was called, the line had a standard ringing cadence, instead of the single long ring you'd normally get with faxability. Therefore their fax machine when set to faxability mode (distinctive ring)  just ignores all calls thinking they're just regular phone calls, as you'd expect. A call to Telecom support confirmed that the Browns Bay exchange is "too old" to support faxability, and hence my customer has been given "dual number' instead. The CSR told me we need a fax machine that supports "dual number" or the ability to answer when it receives calls from the allocated fax number only. I can't believe Browns Bay could still be in the dark ages - hey it's a pretty big suburb on the North Shore feeding some of the bays including us here in Mairangi Bay also. Does anyone know where I can find such a fax machine, and models? I've never heard of them, and I'm not sure if they even exist. the Telecom CSR didn't have a clue either.
