I am working on an fax grabber, for a fax in our building only Samsung provides the software "Samsung Easy Printer Manager" the program sends an SNMPGET to the Printer as I saw in Wireshark

I use Eclipse Milo (0.2.3) in my prject for OPC UA communication. The OPC UA participants are a client (written using Eclipse Milo) and a server, which is running on a remote machine, and is not implemented using Milo).
I can connect the client to the server normally and if the remote server is shut down, I am able to reconnect the client automatically, as soon as the server is accessible again.
However, after updating the server software, the client can't reconnect any more and it floods the server with the following messages:
Create Session Request
The server is able to create a session
Activate Session Request
The server sends an Activate Session Response, in which the ServerNonce is missing and the service result is "bad"
This causes the client to send a new Create Session Request. This all happens multiple times within a second, which makes it impossible for the server to execute any other tasks then trying to create this session.
Are there any settings in Milo to specify the reconnection delay? Or is there any setting for sepcifying what should happen when receiving an empty ServerNonce?
The server's responses are as follows:

Thank you in advance for your help.
This corner case you described where there's no delay between a failed re-activation and the subsequent re-creation is addressed on the dev/0.3 branch in this commit.
I might be able to back port it to 0.2.x next week if I have some spare time.
I don't think there are any workarounds you can use.
I am trying to run H264 encoded live stream in Web Browser using Janus WebRTC Gateway. While testing with Chrome, the stream works fine but with firefox it shows ICE failed, add a TURN server and see about:webrtc for more details.
Following is my about:webrtc logs for firefox.

I even tried adding following TURN Server
{urls: "turn:numb.viagenie.ca",
username: "l1787875#mvrht.com",
credential: "test"}
But the console error changes to ICE failed, your TURN server appears to be broken, see about:webrtc for more details, Keeping the about:webrtc logs same as before.
I figured out that somehow Firefox can't generate a valid answer for SDP offer generated by Janus. Created answer by Firefox has attribute rtpmap: 120 VP8/90000, whereas SDP offer made by Janus has attribute rtpmap: 127 H264/90000, which prevent Firefox to establish a SDP session with Janus. Chrome can generate the valid answer with rtpmap: 127 H264/90000 so it can display the stream perfectly.
I am using Mozilla firefox-57.0.4.
Is there a way, I can get/ generate a valid SDP answer for incoming SDP offer from Janus?
This solution worked for me (last yellow message):
https://groups.google.com/forum/#!topic/meetecho-janus/jKg5u9421kM
I'm using Janus and I was getting the same error in Firefox.
The problem was about the SDP profile-level-id.
I just had to replace it:
// Create offer/answer now
if(jsep === null || jsep === undefined) {
createOffer(handleId, media, callbacks);
} else {
if(adapter.browserDetails.browser === "edge") {
// This is Edge, add an a=end-of-candidates at the end
jsep.sdp += "a=end-of-candidates\r\n";
}
var oldsdp = jsep["sdp"];
var pattern=/420029/gi;
var newsdp = oldsdp.replace(pattern,"42e01f");
Janus.log(newsdp);
jsep["sdp"]=newsdp;
config.pc.setRemoteDescription(
new RTCSessionDescription(jsep),
function() {
Janus.log("Remote description accepted!");
createAnswer(handleId, media, callbacks);
}, callbacks.error);
}
}

Is PJSIP supports PJSIP_HEADER for WebSocket? Is there any other way to add custom header to INVOTE for webrtc client?
I use asterisk 13, and siphtml5 web client. Also I check wss traffic with wireshark, decrypt it and still can't find X-DRP header.
In asterisk set header using:
same => n,SIPAddHeader(HEADERNAME: ${SOMEVAR})
You need use a more updated library like jsSip in client. In this case you cant get the server header like this:
phone.on('newRTCSession', function(e){
if (e.originator == 'remote') {
console.log(e.request.headers);
}
});
