I use a GN 9330 wireless headset at work. It has been working fine. since I also work from home, I tried to install it on my home phone, but it does not work. It seems like it works but when I click the answer button, I get silence, no dial tone. I took it back to work and it is fine there. Does this product require a certain type of phone system (e.g. phone system used by larger companies like Nortel, etc.)?
