-----------------------------------------------------------------------
'Could not set SRTP policies' error looks come from the media-level SDP subsystem (audio).
I have compiled asterisk version 1.8, 11.5, 11.6, 11.7 and 12+pjproject (beta), using
./configure --with-crypto --with-ssl=ssl --with-srtp
In all of them I have got the same error.
Here is a comparison between a two asterisk (1st the wrong one and 2nd a good one)
1) debug info for 'Could not set SRTP policies' in v 11.5, 11.6 and 11.7 :

--------------------------------------------------------------------------------
Main differences:
a) In (1) Asterisk doesn't seem to parse "a=candidates" lines reported by the WebRTC client (sipML5 in my case). (UNSUPPORTED OR FAILED)
b) In (1) this files related to SRTP policies are not called/processed:
- res_srtp.c: Adding new policy for SSRC
- sip/sdp_crypto.c: SRTP policy activated
- sip/sdp_crypto.c: Accepting crypto tag 0
c) In (2) ICE candidate is accepted (OK), unlike (1)
Not sure, but it seems 'UNSUPPORTED OR FAILED' ICE candidates implies -> 'Could not set SRTP policies'
In adition, asterisk12 is able to process 'a=candidates' without problem, but still show the same error "Could not set SRTP policies"
Should I provide more parameters than "./configure --with-crypto --with-ssl=ssl --with-srtp" ?
BTW: module res_srtp was always loaded at the start without errors.
Any suggestion?
Miguel Oyarzo,

was (Author: miguelaustro at gmail.com):
'Could not set SRTP policies' error looks come from the media-level SDP subsystem (audio).
I have compiled asterisk version 1.8, 11.5, 11.6, 11.7 and 12+pjproject (beta), using
./configure --with-crypto --with-ssl=ssl --with-srtp
In all of them I have got the same error.
Here is a comparison between a two asterisk (1st the wrong one and 2nd a good one)
1) debug info for 'Could not set SRTP policies' in v 11.5, 11.6 and 11.7 :

--------------------------------------------------------------------------------
Main differences:
a) In (1) Asterisk doesn't seem to parse "a=candidates" lines reported by the WebRTC client (sipML5 in my case). (UNSUPPORTED OR FAILED)
b) In (1) this files related to SRTP policies are not called/processed:
- res_srtp.c: Adding new policy for SSRC
- sip/sdp_crypto.c: SRTP policy activated
- sip/sdp_crypto.c: Accepting crypto tag 0
c) In (2) ICE candidate is accepted (OK), unlike (1)
Not sure, but it seems 'UNSUPPORTED OR FAILED' ICE candidates implies -> 'Could not set SRTP policies'
In adition, asterisk12 is able to process 'a=candidates' without problem, but still show the same error "Could not set SRTP policies"
Should I provide more parameters than "./configure --with-crypto --with-ssl=ssl --with-srtp" ?
BTW: module res_srtp was always loaded at the start without errors.
Any suggestion?
