[SR-Users] SIP over WebSockets error: bad request

[Peter Dunkley]

Hello,

Check that you have "tcp_accept_no_cl=yes" in your configuration.

This is required for Kamailio to parse messages over TCP which do not have
"Content-Length:" headers (including HTTP requests).

If that doesn't work try running Kamailio with debug output at its highest
level (you'll need to output debug to stderr when doing this as syslog
won't capture it all) so that more detailed debug can be provided to track
this down.

Regards,

Peter
