'Audio producer not started yet' and 'No matching state found' in webrtc2sip #335

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. *** This problem is random
2.
3.

What is the expected output? What do you see instead?

Audio producer should be established after state machine is 
- x0000_Connected_2_Connected_X_iACK. 

However, log shows:

*INFO: State machine: tsip_transac_ist_Accepted_2_Accepted_iACK
*INFO: State machine: x0000_Connected_2_Connected_X_iACK
*INFO: State machine: No matching state found.
*INFO: Audio producer not started yet
*INFO: Audio producer not started yet
*INFO: Audio producer not started yet
*INFO: Audio producer not started yet
*INFO: Audio producer not started yet
*INFO: Audio producer not started yet
.
.
*INFO: Audio producer not started yet
*INFO: Audio producer not started yet

The processes seems never reaching:
- 'ICE_ConnChecking_2_ConnCheckingCompleted_X_Success' state

Signalling is still working, but media is totally missing (sometimes).

What version of the product are you using? On what operating system?
Doubango 2.0 source
Linux Ubuntu 12.04
Asterisk 11.5
SipLl5 (breaker enabled)
ICE servers:  default google and own produce same result (random failure)
webrtc2sip last version

Please provide any additional information below.

Sample1:  Good call with no issues in audio, after SIP ACK:

file: "src/ice/tnet_ice_ctx.c" 
line: "1485" 
MSG: ConnCheck timedout, have_nominated_answer=false, have_nominated_offer=false

Note: 
- This call didn't reach 'ICE_ConnChecking_2_ConnCheckingCompleted_X_Success' 
state.
- As a result, no audio at all, but signalling (ringing, ACKs, etc) still works.

Additional notes:
=================

In ./tinyNET/src/ice/tnet_ice_ctx.c
In function _tnet_ice_ctx_fsm_GatheringComplet_2_ConnChecking_X_ConnCheck(..) {
.
.

                if((ret = select(fd_max+1, &set, NULL, NULL, &tv))<0){
                        TNET_PRINT_LAST_ERROR("select() failed");
                        goto bail;
                }
                else if(ret == 0){
                        // timeout
                        // TSK_DEBUG_INFO("STUN request timedout.");
                        continue;
                }
                else if(ret > 0){
                .
                .
                }
.
}

When audio/media works well, ret=1 // there is data to read and media 
processing continues.

However, when ret is always 0, log shows 
"*INFO Audio producer not started yet" 
and TSK_DEBUG_INFO("STUN request timedout") is reached.

It seems that select() can not find data at in file descriptors and the code 
remains in loop until timeout is reached, sometimes.

As I stated before this issue is random (1 out 5 calls seems to fail). At first 
I blamed  STUN time server responses (latency) but I have installed a local 
STUN and got same results.

Attached is my config file for webrtc2sip wi.

Any idea?

Hi, 

I am also facing this issue when try to make call from linphone to web-browser 
(using sipml5). Issue is always reproducible in my environment.

I have checked on google and found that many people are facing same. However no 
answer found that work for me. 

If anyone have some suggestion regarding resolution of this issue, please let 
me know also.

Thanks and Regards
Vinod Pandey
