I know the SPA 500 phones (except for 501) will support extension mobility if they are configured as SIP. In doing that, do I lose any other feature functionality by NOT using SCCP? Such as SNR, fax to email, etc...
EM was added on a recent release to the SPA500 phones, so I imagine you check some old documentation or documentation that has not been updated. If you have the link please let me know so that we can update the documentation.
