How to enable audio streem?

maheshlalu · 2019-12-27T08:52:42Z

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

cloudwebrtc · 2019-12-27T10:03:34Z

Please confirm your server supports RTCP-MUX.

maheshlalu · 2019-12-27T10:07:49Z

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

maheshlalu · 2019-12-27T11:50:43Z

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

maheshlalu · 2019-12-30T07:55:45Z

Please help me out, I am getting same issue.

cloudwebrtc · 2019-12-30T11:03:09Z

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

maheshlalu · 2019-12-30T11:06:35Z

can you provide me sample code.

maheshlalu · 2019-12-30T12:15:45Z

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

@cloudwebrtc please help me out

maheshlalu · 2019-12-30T13:09:41Z

@cloudwebrtc please update on it.

cloudwebrtc · 2019-12-30T13:13:50Z

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 · 2019-12-30T13:34:13Z

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

maheshlalu · 2019-12-30T14:32:25Z

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

maheshlalu · 2019-12-30T15:12:59Z

@cloudwebrtc pls update me

cloudwebrtc · 2019-12-30T22:30:14Z

@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 · 2019-12-31T06:35:05Z

@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 · 2019-12-31T07:38:22Z

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

maheshlalu · 2019-12-31T07:52:51Z

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

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

cloudwebrtc · 2019-12-31T09:47:54Z

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:

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

maheshlalu · 2019-12-31T10:19:40Z

@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 · 2019-12-31T10:31:30Z

@cloudwebrtc I am getting this error
