Hello,

see if this parameter gets what you are looking for:

Hey all,

I'm using Kamailio as an outbound edge proxy for websocket connections. When my registrar calls out to Kamailio to forward to a websocket connection that has since been killed, rather than just entering the failure branch, it throws a few errors:

 5(24) WARNING: <core> [msg_translator.c:2760]: via_builder(): TCP/TLS connection (id: 0) for WebSocket could not be found

 5(24) ERROR: <core> [msg_translator.c:1978]: build_req_buf_from_sip_req(): could not create Via header

 5(24) ERROR: tm [t_fwd.c:476]: prepare_new_uac(): could not build request

 5(24) ERROR: tm [t_fwd.c:1737]: t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches

 5(24) ERROR: sl [sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: No error (2/SL)

Ultimately this means the proxy gets a 500 rather than a 430 flow failed, and the registration sits around in the proxy when it should be removed.

Am I missing something obvious to get this behavior?

Best,

Colin
