This Polycom PSU is made specifically for use with the Polycom SoundPoint IP 320 and SoundPoint IP 330 VoIP phones.
SoundPoint IP320 & IP330 Compatible
The Polycom SoundPoint IP 320 and 330 phones are not supplied with a PSU and require a power supply to work, it is therefore highly recommended to purchase one of these Polycom PSU’s alongside the purchase of either the Polycom SoundPoint IP 320 or IP 330 VoIP phone.
This Polycom PSU is available in a single pack and a pack of 5.
