ok so I pushed the flag to be set so now it should work out of the
box, thanks for testing.

Hello Anthony,
That seems to work better than my attempt!
Thanks for your help!

try patch in latest head minus your plc hack.
I have not made any changes to mod_dingaling yet but the core should
not try to decode stun now.

Hello Anthony,
Thanks for your quick response!
does it work then? I had it disabled on purpose cos I have not
confirmed it works yet.
That would explain it then :-)
I have managed to get SRTP working for the outbound voice path, but it
required 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 to
switch_rtp.c:read_rtp_packet() but I suspect this will stop inbound voice
paths 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 the
crypto_type and crypto_send_type/crypto_recv_type members of
tech_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 path
tomorrow.
Regards,
Richard

Using mod_dingaling I am unable to get it to append the crypto details to
