Disabling Vodafone autoprovisioning on Snom 821
I bought a nearly new Snom IP phone on eBay, but it was getting autoprovisioned as a Vodafone device. I wanted to use it as a SIP phone on another provider’s network, so needed to get rid of this.
I’ll try to write down the steps I followed, but I tried quite a few things so there may be inaccuracies.
Basically this phone tries three ways to autoprovision itself:
1. Redirection – it goes to a host run by Snom, is redirected to a Vodafone host and autoprovisions from there.
2. PnP – I think this is where it multicasts for a configuration server.
3. DHCP – where it receives details of the configuraiton server from DHCP options it receives with its IP address.
Redirection is the first one it tries by default, so you need to stop this happening. Snom say on their forums that they can’t do this for Vodafone devices, which must be a legal thing between them and Vodafone, because they are able to do it for Snom phones that are auto-provisioned on other providers. In the latter case a simple request on the forums with the phone’s MAC address appears to be sufficient.
