[Spce-user] webRTC in production

[H Yavari]

Hi,very thanks for reply.I had a mistake. browser to soft phone is established but after 30 sec call will be terminated although the media is two way and I think is not related to rtp timeout . but soft phone to browser and browser to browser have this error: ""Failed to get local SDP"".
Can you explain more about your changes? and account configs soft phone changes?
I used webrtc2sip with asterisk but I received DTLS-DTLS handshaking error in the webrtc2sip logs. Thanks so for your hints.

Hi,not sure if I understood correctly which scenario works and which not. So browser to soft phone is now working, but what is the meaning of browser to client? Which client?
I tested myself and I have to confess that I had to do some changes in the account configs for soft phones where I am not happy about.It only worked between browser-webrtc  and soft phone when the corresponding account for the soft phone - nat & media flow control had been changed to "force avp"“ and "force rtp“ ie. no encryption.(I have to investigate that one - could be related to an upgrade I had performed last week - usually srtp should also work with softphones, within the ftp.log there was „SRTP output wanted but no crypto suite was negotiated“).However, after my changes the following tests had been successful:browser webrtc  to  softphone (eg. jitsi,  counterpath x-lite - should be software compatible with eyebeam)browser webrtc to  another browser webrtc (jssip-0.50)browser webrtc to pstn via sip trunking  (standard sip trunk, peer settings for media  force „rtp“, „force rtp“, „always with plain SDP“)
That is based on the latest SPCE version 3.6.1.What does not seem to be achievable at the moment that you can have an account that supports „standard“ and webrtc simultaneously ( at least I haven’t succeeded with such a setup, maybe some sipwise/kamailio/rtpengine  expert knows the trick). And I do not have a solution yet how to share one phone number between two accounts with different profiles.The only solution I have at the moment is that I put a webrtc gateway (similar to webrtc2sip  from doubango) in front of SPCE for webrtc clients.
For your particular problem, maybe you have to check whether your domain settings allow „bypass rtp proxy“ behind the same NAT - assuming you are testing wthin your LAN - this should be set to never.
Good luckThomas

Hi,
I did this configs:use_rtpproxy:   „Always with rtpptoxy as only ICE candidate“ 
rtcp_feedback:  „Force AVP“ 
srtp_transcoding:    „Force RTP“
now calls between browser to soft phone is ok, but browser to client and browser to browser receive this error "Failed to get local SDP"and calls not be established. Have you any idea about this situation? 
Thanks for helps.

Regards,H.Yavari
