I am working on the same project. This issue has a bad impact, some calls are lost. I see that there is a issue on Github: https://github.com/signalwire/freeswitch/issues/1041 [https://opengraph.githubassets.com/4e12492b46ac88ed6577f3abc386901b70d2c46c2c65714cc448439d62ef425e/signalwire/freeswitch/issues/1041]<https://github.com/signalwire/freeswitch/issues/1041> sip.js websocket terminated by Freeswitch · Issue #1041 - GitHub<https://github.com/signalwire/freeswitch/issues/1041> Hi everyone, we are currently running a custom-build phone application using sip.js which registers to the websocket of our Freeswitch. Our Freeswitch uses version 1.10.3 64 bit on a Debian buster.... github.com  We made logs and pcap traces, the websocket close happen on effective trafic, often after the 200 OK from (WebRTC) callee which is a big packet. It should be linked with TCP segmentation, sometimes the issue occur when the OK packet is coming in 2 segments from network. I send 2 pcap traces with SIP on a-leg and TCP:7443 on WebRTC leg, on both trace the Websocket is closed by Freeswitch. What is your advice: * Do we have to use Nginx or Kamalio to handle wss before Freeswitch ? * Are there any settings we should find to reduce the occurence ?? Best regards.

The error message on javascript console on Chrome is "error 1006 - websocket unexpectly closed" This issue is very random but very often, and it breaks the incoming call. Do you experiment such issue ? Do you know how to solve it ? thanks Franck
