## Questions & Answers

**Q: Will this work with a cordless telephone and a headset attached to the telephone?**
A: Hi, I've had a hard time finding a useful headset that will work with the phone and the device at the same time. Every product that I have used has not worked.

**Q: will this work with a nortel phone? it says "please check if your phone system is compatible-with this adapter" but it doesn't list compatible systems**
A: Not sure. We use it on Cisco phone system. Don't know why it wouldn't since it just plugs into regular headset cord.

**Q: I have a Olympus VN-702PC Voice Recorder and a land line phone. Is this the only other piece of equipment I will need to record calls?**
A: Hello, Yes, I suggest you ensure you have a  voice recorder with noice canceling capability.  I used a recorder without that feature and the quality of recording was very difficult.  I highly recommend this little device. Good Luck!

**Q: Does not record**
A: I'm not sure if this is a question or a statement. This item does not, in fact, record.  It must be plugged into the mic port of a recording device.  Hope this helped.
