Unable to RTCPeerConnection::setRemoteDescription: Error Failed to set remote answer sdp: The m= section:audio is invalid. RTCP-MUX is not enabled when it is required.

[cloudwebrtc]

This is not the fault of dart-sip-ua itself, but the problem of SDP negotiation. You should analyze the problem from the offer/answer process.

You must have a SIP server that supports the WebRTC media transfer protocol, which means that the offer SDP that you send from your SIP Server to dart-sip-ua must follow the WebRTC standard. Because the webrtc native library in dart-sip-ua is compiled by Google.

[maheshlalu]

Please help me how to solve this. Based on this functionality we will decide to choose the platform either flutter or not.

[cloudwebrtc]

Please confirm your server supports RTCP-MUX.

[maheshlalu]

in web side it's working. is there any difference between web and mobile?

[maheshlalu]

Please confirm your server supports RTCP-MUX.
Yes Supported. But how to negotiated from code?

[maheshlalu]

Please help me out, I am getting same issue.

[cloudwebrtc]

This is a webrtc SDP negotiation problem, you need to analyze the offer/answer SDP.

[maheshlalu]

can you provide me sample code.

[maheshlalu]

I have used your example with my server details, call connected after 6 sec I got issue like]

Bad Media Description, Reason: Not Acceptable Here
flutter: ^[[38;5;196m[2019-12-30 17:40:23.490] Level.error rtc_session.dart:2345 ::: emit "peerconnection:setremotedescriptionfailed" [error:Unable to RTCPeerConnection::setRemoteDescription: Error Session error code: ERROR_CONTENT. Session error description: The m= section:audio is invalid. RTCP-MUX is not enabled when it is require

@cloudwebrtc please help me out

[maheshlalu]

@cloudwebrtc please update on it.

[maheshlalu]

We done from web app, it's working good. Our server supported WebRTC.
@cloudwebrtc

[maheshlalu]

@cloudwebrtc can you please provide me your test server, I can test from end. kindly provide me.
Thanks.

[maheshlalu]

@cloudwebrtc pls update me

[cloudwebrtc]

@maheshlalu You can analyze the differences in SDP between normal calls and failed calls, and you should be able to locate the problem quickly.

[maheshlalu]

@cloudwebrtc I have set the 'rtcpMuxPolicy':'negotiate' in SIPUAHelper class and then
call connected successfully but media not working both sides. Could you please check once.

[cloudwebrtc]

@maheshlalu You can use Wireshark to capture and analyze udp to confirm that the media stream is connected

[maheshlalu]

@cloudwebrtc pls look into below log. media not transferred.

flutter: call CONFIRMED

[maheshlalu]

@cloudwebrtc my server team told me that this is NAT issue. Please give me any idea how to solve this.

[cloudwebrtc]

Dart-SIP-UA to Asterisk:

a=candidate:589742960 1 udp 2122260223 192.168.4.28 59301 typ host generation 0 network-id 1 network-cost 10
a=candidate:3724891700 1 udp 2122194687 169.254.186.35 58387 typ host generation 0 network-id 2 network-cost 10
a=candidate:589742960 2 udp 2122260222 192.168.4.28 52046 typ host generation 0 network-id 1 network-cost 10
a=candidate:3724891700 2 udp 2122194686 169.254.186.35 55666 typ host generation 0 network-id 2 network-cost 10

Asterisk To Dart-SIP-UA:

a=candidate:Ha0000a0 1 UDP 2130706431 10.0.0.160 10168 typ host
a=candidate:Ha0000a0 2 UDP 2130706430 10.0.0.160 10169 typ host

Your caller and called party is not on the same network segment, and Asterisk is behind NAT. The candidate provided by Asterisk only has the intranet host, so ice cannot connect.
Two solutions:

1. Configure turn server for dart-sip-ua
2. Configure stun server for asterisk to generate reflection candidates. If it is symmetric NAT, this solution will be invalid.

@cloudwebrtc Thanks for solution. As per your instruction I have configured the turn server then it's working good. But Call disconnected after 90 sec. Please check once.

[maheshlalu]

@cloudwebrtc I am getting this error

emit "peerconnection:setremotedescriptionfailed" [error:Unable to RTCPeerConnection::setRemoteDescription: Error Failed to set remote offer sdp: The order of m-lines in subsequent offer doesn't match order from previous offer/answer.]<…>
