Jabra QD to Modular RJ Coiled Cord for Cisco IP Phones (8800-01-37)
Coiled bottom cord that connects any Jabra Quick Disconnect (QD) headset to a Cisco IP desk phone via the modular RJ headset port — 2 metres stretched, neatly retracts when not in use.
Jabra QD to RJCoiled, 2m stretchedCisco-specific wiringPlug & play
The Jabra 8800-01-37 is a coiled headset bottom cord designed specifically to connect a Jabra Quick Disconnect (QD) wired headset to Cisco IP desk phones that use a modular RJ-9 headset port. The coiled shape means it stretches up to two metres when you walk around your desk and retracts neatly when you sit back down, keeping the headset wire under control. Cisco-specific wiring ensures correct audio routing — generic QD-to-RJ9 cords will often not work properly on Cisco handsets.
Compatibility Note: Wired for Cisco IP phones — confirmed compatible with Cisco IP 69xx, 78xx, 794x, 796x, 797x, 89xx and 99xx series. This is not a universal QD-to-RJ9 cord — for Avaya, Yealink, Polycom, Siemens or other vendors use the corresponding Jabra Cord with the correct vendor wiring.
Key Features
Cisco-Specific Wiring
Pinout matches Cisco IP phones' modular headset port for full audio routing — bidirectional voice without the level or microphone problems of generic cords.
Coiled for Tidy Desks
Coiled construction stretches to 2 m when you need to move and contracts back when you don't — keeps a permanent desk-phone install free of cable clutter.
Works with Any Jabra QD Headset
Standard Jabra Quick Disconnect on the headset end — drop in with Biz / Engage / Pro / GN series QD headsets without re-cabling.

Frequently Asked Questions
Will this cord work on any RJ-9 desk phone?
No. The 8800-01-37 is wired specifically for Cisco IP phones. Other vendors (Avaya, Yealink, Polycom, Siemens) use different pinouts — choose the vendor-specific Jabra QD-to-RJ cord for those phones.
Which Cisco IP phones are supported?
It works with the Cisco IP 69xx, 78xx, 794x, 796x, 797x, 89xx and 99xx series. Confirm your specific model has a modular RJ headset port.
Will my Cisco IP phone need any setup for headset audio?
In most cases enabling headset audio is a single button or menu setting on the phone. Refer to the Cisco model's user guide for the headset-enable steps.
Is the cord coiled or straight?
Coiled. The cord stretches up to 2 metres in use and retracts when relaxed, keeping the cable neat on a static desk-phone setup.
Singular Expert Insight
Choose 8800-01-37 only if you have a Cisco IP phone — the Cisco-specific wiring is the whole point of this SKU. If you have an Avaya, Yealink, Polycom or generic IP phone, pick the corresponding Jabra cord with the right pinout (8800-00-99, 8800-00-25, etc.). If you want full call control buttons (answer, hang up, volume) from the headset, the simple cord cannot do that — you need an EHS adapter or a wireless Jabra Engage solution.
Buyer's Guide
Buy it if
You have a Cisco IP desk phone and a Jabra QD-equipped headset and want a tidy coiled connection between the two.
Skip it if
You have a non-Cisco phone, you need remote call-answer functionality (use an EHS cable instead), or your phone only has a 3.5mm jack rather than RJ-9.
Also consider
Jabra LINK 14201-43 EHS adapter for full call-control from the headset, or a wireless Jabra Engage 65/75 for cordless freedom at the desk.
