SSRC not Darcy. Did not DoD
Give latest git head unchanged a shot again of you have a chance. That Darcy issue was fixed IIRC. Also I DoD a few rounds of changes.
Btw next time use Jira Jira.freeswitch.org its easier to track stuff. I almost lost this thread 3 pages deep on my email.On Jul 17, 2012 7:03 AM, "Richard Screene" <richard.screene@netdev.co.uk> wrote:Just to give you all the information:A few days ago I hacked the RTP so that the RTP bug NEVER_CHANGE_SSRC_ON_MARKER was enabled.

That would explain it then :-)I have managed to get SRTP working for the outbound voice path, but itrequired a couple of hacks:
1) It was attempting to decrypt the STUN/ICE Bind Requests and failing.I've bodged it for now by passing the SFF_PLC flag toswitch_rtp.c:read_rtp_packet() but I suspect this will stop inbound voicepaths from working!2) In mod_dingaling.c:try_secure() the incorrect crypto_type is passed to
switch_rtp_add_crypto_key(). I suspect there is some confusion between thecrypto_type and crypto_send_type/crypto_recv_type members oftech_pvt->transports. I've hacked it for now as shown below.I hope this is useful to you. I'm going to try with the outbound voice pathtomorrow.Regards,RichardFor reference here are the diffs:
