Welcome to Vodafone Community
I recently bought a Cisco IP Phone SPA525G2 which is locked with the Vodafone OneNet firmware. How do I remove this firmware to use the phone with my own SIP server as I only plan to use the phone at home and therefore cant use OneNet.
Honestly I'm not sure as I've never used one of those phones.
Vodafone wouldn't assume be able to remove a firmware.
You may get some further advise on the Cisco forum.
This is one thread I came across via a Google Search @m4xm0rris
Current Phone > Samsung Note 9 _512Gb > Model: SM-N960 Hybrid-Duos.
Samsung One Ui / Pie.
Samsung Gear s3 Frontier Watch.
The best way to get this solved would be to contact the One Net Team from the contact us link below, they will be able to advise if this is possible.
Also take a look at the unlocking request form below, selecting Vodafone software from the dropdown menu.
