I just need some clarification here.
Are there such things as incompatible phones/faxes? Or, is it just incompatible wiring.
Now that I have switched my main line to VFX I am currently down from the 4 phones I had to 2 phones as two of my phones don't get a dial tone. One of the phones is a bog standard Telecom rental phone, and the other phone is a cordless phone. My fax also doesn't work, but I can keep that on my existing landline.
The two phones that do work are both US sourced phones. I can place the other two phones on the same cable as the ones that work, and no dial tone. The cables are all 4 wires.
Also, I have a slew of old phones that came with a PBX that I bought but never installed 15 years ago. Can I try plugging one of those phones in to my SPA or will I damage something. I recall reading some prohibition about this before ....
