[OpenSIPS-Users] Should opensips support pong on websocket?

[Răzvan Crainea]

Hi, Robert!

Websocket has itself support for ping/pong messages, therefore there's 
no point supporting them at the "application" level. So the answer is 
no, opensips does not support CRLF ping-pong messages for websocket 
connections.
