Hi Everyone,
I want kamailio to do a single task, that is relay incoming (webrtc sip over websockets)
connections to asterisk. All sip handling is to be done is asterisk.
I have configured asterisk with tls settings.
My sample conf file is below
At the moment I am getting these errors
ERROR: tm [ut.h:343]: uri2dst2(): no corresponding socket for af 2
ERROR: tm [t_fwd.c:520]: prepare_new_uac(): ERROR: can't fwd to af 2, proto 3 (no
corresponding listening socket)
Please can anyone provide any advise to complete this configuration
listen=tcp:10.2.3.4:5080
enable_tls=yes
tcp_connection_lifetime=3605
tcp_accept_no_cl=yes
