Customer Questions & Answers

does this have any volume controls?
Answer: No. It only has an off and off switch. Hope this helps.

What voltage does this require to ring?
Answer: it requires a phone ringer to make the pulses or to be plugged into a phone outlet. i’m not sure what just a voltage would do.

Does this require a power source or does it work off the line voltage on the phone line?
Answer: The unit gets its power through the phone line.

Will this work with a polcom ip phone model vvx311?
Answer: Only if you have a converter to analog ringing.

can it be used for two lines?
Answer: it may ring no matter which line is being called, i don’t know, but it definitely only has one physical connection.
