I have problem with offer SDP that firefox nightly generates. It writes out the
following error on asterisk:
WARNING[25424][C-00000004]: chan_sip.c:10936 process_sdp_a_dtls: Unsupported
fingerprint hash type 'sha-2' received on dialog '2457893540'
SDP:

After inspecting the code in Chan_sip.c, metode "process_sdp_a_dtls", looks
like there is only sha-1 supported, but firefox uses sha-256:
if (!strcasecmp(hash, "sha-1"))
{
dtls->set_fingerprint(instance, AST_RTP_DTLS_HASH_SHA1, value);
} else {
ast_log(LOG_WARNING, "Unsupported fingerprint hash type '%s'
received on dialog '%s'\n",hash, p->callid);
}
Is there a support for sha-256 in asterisk and is there a plan to be supported
and when?
