This occurs in the following cases:
SIP devices with buggy or misconfigured VAD stops sending RTP without notifications. After silence sound disappears in the flash-plugin.
Calling to Asterisk IVR: after playing IVR messages Asterisk stops sending RTP and waits DTMF, after receiving DTMF Asterisk continues sending RTP, but the flash plugin does not play anymore.
Workaround: use WebRTC instead.
Do you have console logs for us to review, or a way for us to reproduce? It sounds isolated to a couple usecases you have set up - is the Asterisk server available to be called on our side?
Asterisk server is availiable at sip:541@antisip.com
Problem can be reproduced with kitchen sink or any other applications uses phono API.
Tested with Adobe flashplayer 11.2.202.310/linux and 11.9.900.152/win32 versions.
Update flashplayer to latest version had no effect.
Audiostream is lost only from SIP to flash-plugin direction: starts normally received, then lost.
Asterisk RTP debug shows that RTP transmitted normally.
I used tcpdump (network sniffer) for checking the transmission RTMP-stream in flashplayer.
No packets received after loss sound.
I think, this is bug in phono gateway.
I tried to use different gateway (old flash), the sound is not lost, but the sound quality is poor.
Can you please reproduce and relay the console logs? Our engineers will need that to diagnose this issue.
I am trying to replicate this myself, can you please relay the steps to replicate this issue? Once I have that, we will extract the logs ourselves. We will be standing by for your reply, thank you!
I prepare the script uses new flash only (it's important! webRTC and java does not have this problem)
I calling sip:541@antisip.com
Asterisk playing IVR message
Asterisk stopped playing message and transmit RTP. From this moment the sound disappeared.
I calling extension 200 in IVR
Call is received on the SIP-phone, but still no sound. RTMP is not transmitted to flashplayer.
