This is not enough, and will not work for sure.  Updating to 1.1 is more involved, and will require code changes to freeswitch code as well.  What you are suggesting here will almost for sure cause things to crash.  Furthermore, 1.0.2 is more than enough to address this issue.  I’ve put some comments on the Jira related to this of the details and testing i need done, we can continue the conversation there.  I just want to be completely clear, updating to 1.1 as described here should not be done, and will only cause more issues.  Lets continue this conversation on the Jira for those interested.

And you also copied dlls from openssl instalation to freeswitch root directory?

Hello Gregor,

I have upgraded the openssl version to 1.1.0e from the following link. But the issue remains the same.

http://slproweb.com/download/Win64OpenSSL-1_1_0e.exe

​Is the above way correct to upgrade the open ssl.

​Thanks and Regards,
​Sachin

Clearly that isn't the case, I suspect a define is missing to actually enable ECDSA at this point.

Brian, isn't this solved in 1.6.16?

OpenSSL on the windows build needs to be updated.

This error is familiar to me, I think so, if I remembered correctly. 
 
I am using windows. I had this error when client was Chrome. I just updated openssl dlls. I think that openssl library is updated on windows build now with version 1.6.17. And this version is also compiled on FS FTP to just download and install it.

FS 1.5 sounds like a bad plan.
Try latest FS 1.6 or master.

Hello All,

​I am trying to setup the Webrtc call between 2 SIPML5 client. I am using FreeSWITCH Version 1.6.14 on Windows. I am using internal LAN.

The clients are getting registered over wss. I have created self signed certificates.  In var.xml I have set the codecs setting as follows

  <X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMU,PCMA">
  <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA">

​I am able to establish the call and there is 2 way voice when I call from Sipmpl5 to Linphone and it works. But when I call from Linphone to Firefox (Simpl5) then the call is not getting established and I am getting following error

2017-05-04 11:29:04.543434 [ERR] switch_rtp.c:2907 audio Handshake failure 1

My setup is as follows

SIPML5 (FireFox browser 53.0)<-----> FS (v1.5)(Windows) <----> Linphone

I am attaching the logs for the reference.
fs-logleve9.txt : Debug trace with loglevel =9
​fs-sip-trace.txt : Sip trace
Please let me know what could the issue and pointers to resolve the same.

​Thanks and Regards
