Polycom IP Phone & Plantronics/GN Netcom Corded Headset Compatibility Guide
If you have Polycom Soundpoint IP phones like the IP300, IP301, IP430, IP500, IP501, IP550, IP600, IP601 (Rev E or later) with a dedicated headset jack, it has been determined by Plantronics that it will ONLY work properly with the Plantronics H-Series “SupraPlus” (H251, H251N, H261, H261N) or “TriStar” (H81, H81N) model headsets along with a Plantronics Polaris Cable (part# 27190-01). The other H-Series models will not work properly and it causes a terrible "buzzing" sound.
For GN Netcom/Jabra headstes, use any GN Netcom headset + GN 1200 Smart Cable. Also see our GN Netcom - Polycom Compatbility Guide
If you're looking for wireless for your Polycom IP phones, we recommend Plantronics CS55,or the Plantronics CS70N, however, these wireless headsets must be plugged in through your phone's receiver port, not your headset port. If you're using the Plantronics HL10 lifter remote answering option with your IP phone, you will need the Plantronics Lifter Accessory for Polycom IP Phones.
If you have the model SoundPoint IP 320, 330, 430, 550, 560,
650, 670, you can use the Plantronics APP-5 hookswithc cable with any of the Plantronics wireless headsets without the use of the HL10 lifter, see below:
