Hi
We have this situation with poor audio quality (noise, echo) and after investigating several of our endpoints we did not find any issue in the network or on the SIP end.

I've sent some logs to logs@flashphoner.com address.

1. This is the call with problems, found in flashphoner_manager.log.2017-09-26-13 at 13:55:

13:55:33,577 INFO agerRemoteRmiService - RMI TCP Connection(675)-172.31.25.198 SEND REST OBJECT ==>

"mediaProvider" : "WebRTC",

"holdForTransfer" : false
}

2. Also there is a .pcap with this exact call. (its the stream between Flashphoner server and Asterisk PBX). The RTP stream seems to have Jitter..but I don't know if this Jitter is due to the connection between Client browser and WCS.
3. Version we are using is : FlashphonerWebCallServer-5.0.1994

Any help is highly appreciated.

Hello

1994 is quite old version of server and is not currently supported.
You have to update to the latest one https://flashphoner.com/download
Once it is updated, please send pcap dump and logs to logs@flashphoner.com
We will check.

How to create pcap
tcpdump udp -s 4096 -w log.pcap
