## 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.
