You need to use Digest Authentication in freeradius. you need to add the
digest module at the authorization scheme in the radiusd.conf. Sip
clients traffic digest data to send and receive authentication
information. When using digest, no User-Password nor CHAP-Password
attribute is sent. The password "travels" inside the digest information
to the RADIUS Server. The RADIUS server receives the info sent by SER,
recovers the information from digest data, and validates the user.
