Review: This product works great. THIS IS NOT A PHONE LINE SPLITTER! This works 2 ways it is for taking 2 separate phone numbers running on one prone line and dividing each phone number onto two separate phone lines (1 phone number per exiting phone cord) Or the second way .. if you have a phone that has 1 port for 2 separate phone numbers this will take 2 phone lines with 2 separate numbers on them and it puts both phone numbers on a single phone line. That's the simplest terms I can put it in. It looks like the similar product that takes 1 phone number and allows you to have that 1 phone number on 2 separate phone cords...but again...this is not that! This does exactly what it says it does.

## Questions & Answers

**Q: I need a bulk order of telephone cords quickly. Should I choose Amazon Prime or Ships from RetailAndBulk?**
A: Ships from RetailAndBulk is fastest for bulk orders. We ship all telephone cables in one shipment the next business day from our NY workshop where we make them. Prime may need to transfer stock to one warehouse first or send multiple packages.

**Q: Are these telephone splitters compatible with all landline phones such as AT&T, Panasonic, and cordless phones?**
A: Yes, but note — this is not a phone jack splitter that simply splits a single-line phone service into two jacks for using two phones on the same line.  This adapter splits a 4-conductor RJ11 2-line cable into separate jacks for Line 1 and Line 2.

**Q: What is the difference between this RJ11 Line Separator/Combiner and a standard 2-way phone jack splitter?**
A: This RJ11 Line Separator/Combiner is designed for two-line phone service, where a single 4-conductor RJ11 cable carries Line 1 and Line 2. It separates those lines into individual single-line jacks, each with its own phone number.

**Q: Does this phone line splitter come with a phone cord?**
A: This listing is for the adapter only. We also offer a combo option [adapter + custom size phone cord]. Scroll to the top of the page to select it — there you can choose a phone cord length from 2 inches to 15 ft along with the phone line splitter.

**Q: Do you offer bulk discounts on large orders?**
A: Yes, if you have an Amazon Business account, you will see it when adding large quantity to cart. We’ve served many large-scale projects, including hotels, retail chains, new constructions, schools, hospitals, TV stations, and fire departments.
