If you're using a Jabra corded headset with a Cisco 78xx or 88xx series phone and want adjustable microphone volume — not just a channel switch — the Jabra GN1218 is the cable for it.
Quick answer
GN1218 vs the standard GN1200 Smart Cord
People often assume the GN1200's channel selector switch is a volume control — it isn't. The GN1218 is the cable that actually adds adjustable microphone volume, on top of the same basic Cisco connectivity the GN1200 provides. If your callers can't hear you clearly enough on a standard GN1200 setup, the GN1218 is the fix — but only if your phone is on the compatible list below.
Myth
The GN1218 works with any Cisco phone in the 68xx/78xx/88xx range, since they're all similar model numbers.Reality
Not true — the GN1218 is designed specifically for the 78xx and 88xx series, and does not work with the Cisco 6851 or 6945, despite the similar numbering. Confirm your exact Cisco model against the compatible list before ordering.Compatible Cisco phones
The Jabra GN1218 is compatible with:
- Cisco 7811, 7821, 7841, 7861
- Cisco 8811, 8821, 8841, 8845, 8851, 8861, 8865

What is the Jabra GN1218 cable?
The Jabra GN1218 is a bottom cable that connects a Jabra corded headset to a Cisco 78xx or 88xx series phone, adding adjustable microphone amplification beyond the standard GN1200 Smart Cord's channel selector switch.
What's the difference between the GN1200 and GN1218?
The GN1200 has a channel selector switch to match your phone but no volume adjustment. The GN1218 adds adjustable microphone amplification, useful if standard call volume isn't loud enough for your callers to hear you clearly.
Does the GN1218 work with the Cisco 6851 or 6945?
No. Despite similar model numbering, the GN1218 is designed specifically for the Cisco 78xx and 88xx series and is not compatible with the 6851 or 6945.
