missing ssl_set_dtls_srtp_protection_profiles function in ssl.h
Building linphone requires polarssl 1.4, which defines the function "ssl_set_dtls_srtp_protection_profiles" necessary for enabling DTL-SRTP support, and unfortunately this function is missing in current polarssl version.
Can you please state when polarssl 1.4 will be publicly available, or how can I overcome this issue ?
The Linphone distribution should contain their version of mbedtls 1.4.
The SRTP addition is one that they developed and has not (yet) been integrated into our mainline.
I suggest you contact them if you have any further questions there.
