SPA 303 not provisioning

[PatrickTodd]

So I followed the http://www.3cx.com/sip-phones/cisco-spa/ how-to and also updated the SPA to the latest firmware (7.6.1)

I entered the provisioning link but the phone does not seem to want to provision. Is the SPA 303 still supported or are the instructions different?

I also have option 66 setup which works for the fanvil and yealink phones I have.

They are still in the list of supported devices: http://www.3cx.com/support/

I just pulled one out to test it and it was on v7.5.5 at the time. From that time a tried:
- Provisioning it from a Factory Reset it state on v7.5.5.
- Upgrading the Firmware from the Management Console to v7.6.1.
- Provisioning it from a Factory Reset it state on v7.6.1.

All of the above worked fine, except for the last one in which case I had to reboot it through the phones menu, but I probably did something else wrong.
Also it is worth noting that I had the latest V14 Cisco template when I tried the above.

One common mistake I have seen though generally is, remember not to use the https provisioning link, cisco phones only support http prov links so adjust the port also accordingly.
