[SR-Users] SIP over WebSockets

[M. Salman]

Hi Nicolas,

Looking at your logs and script lines, it seems you do not have websocket
module installed.

First check your module directory, based on script you are using:
https://github.com/caruizdiaz/kamailio-ws/blob/master/modules.cfg#L42 that
you have websocket module in it or not, if not install it.

You can check you config by issuing command - kamailio -c to validate if
the script file is alright or not.


Regards,
Salman
