 var answer = await sip?.createAnswer();
 await sip?.accept(sessionDescription: answer);

Can you verify your configuration on janus sip demo on their official website? If it works there then i will investigate it otherwise it has got something to do with your sip service

I have java script client that works fine with my sip configuration and outbound is working fine with this client , only answering the incoming call is the problem

After debugging , it appears that await sip?.handleRemoteJsep(event.jsep); was not configured properly when receiving incoming event , the error was ambiguous and miss leading me in another direction , i suggest edit your example take that line of of the method that handles the UI showIncomingDialogBox or something like that , anyway thank you @shivanshtalwar0 for your effort and help

Answer 15 · 2024-02-14T15:04:39.000Z

Thanks for your debugging as well, i would appreciate if you could make a little pr for the same if you have time otherwise no problem i will do later

I added a pull request with changes needed to make the sip plugin work correctly , and i will also add another pull request to update the example to be more informative
