Does anyone know how to convert a Cisco 521G or 524G Phone to use SIP protocol instead of the proprietary SCSP?
First off, if you're using it with a UC500 why would you change it to SIP and lose the functionality you get with SCCP Second, as edgeoff said, the SPA942 is the same handset but SIP firmware if you want it with another call control server.
not all cisco phones have a SIP firmware version.
These phones are similar to the Linksys phones, so buy a SPA94x instead for SIP.
