Error When try to create an answer
Closed this issue · 16 comments
When i receive an incoming call and try to call accept
i got error e = "Unable to RTCPeerConnection::createAnswer: Error (null)"
This happens whey i try to do as you in example , like the following :
var answer = await sip?.createAnswer();
await sip?.accept(sessionDescription: answer);
Any what what could be the problem of how i can solve it ?
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
Any update ?
Please try using 2.2.14 and tell me if that works for you in the meantime i will fix it
can you try latest commit if it works for you and let me know?
Actually your commit doesn't fix it , the problem still occurs
Ok tell me platform on which you are experiencing this issue
Ok tell me platform on which you are experiencing this issue

I still need time to investigate it, thank you for your patience
Any update here ?
hi @mazen930 so i tried on two ios simulators with test sip credentials and everything seems to be working just fine i will need more info on your issue to reproduce the problem
Below is the full error appears when i try to create an answer , i use actual phone to test ,not an emulator , i appreciate if you can look it it

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
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
