£291.00 inc. VAT
AI-generated summary
The HP Poly CCX 505 is one of those “it just works” office desk phones—solid build, decent audio, and PoE means you’re not hunting for extra power adaptors or messing around with cabling more than you need to. At **£244.13 ex-VAT**, it’s priced like a mid-range business phone rather than a bargain basement SIP handset, so you want it for teams who actually place calls daily and want reliability over tinkering. The Open SIP angle is handy if you’re not locked into one vendor, and it’s a good fit where you’ve already got the PBX/UC figured out.
That said, I wouldn’t buy it blindly if your environment is small or your call setup is still in flux. SIP phones are great—but only once you’ve got the numbering, provisioning, and call features sorted on your side. If you’re using it with a provider or platform that’s picky on configs, you may find yourself spending more time on deployment than the savings were worth. In short: **buy it if you’re standardising a fleet for an office/branch using SIP and you value PoE simplicity**; **skip it if you’re unsure of compatibility or expecting it to “plug in and magically add features”**.
