Team,

We are deployed Wazo-platform on AWS Ec2 instance with Debian 10 buster.  
Instance type m5.large.  
Issue : When we try to make a call from Wazo WebRTC sdk, call was connected but audio not working.

Can you help me to resolve this issues.

Thanks in advance.

To help you we need pcap or logs from the call. Check your SDP.

Audio is working with other network,patricularly few networks not receive rtp packets while using  
wazo. the same network work with other webrtc solutions.  
what would be a problem?  
we are not able to identify it.

You need to check the SDP to find the issue with media in your SIP trame.
