[Raj Roy Ghandhi]

I am using Kamailio 4.0 SIP Proxy GW  + WebRTC2SIP 2 web socket GW to
maintain the presence status of SIPMP5 clients.

When I subscriber for presence statue of contact I get the following error
and no record get inserted into the "active_wathcers" table.

 5(7435) WARNING: <core> [msg_translator.c:2499]: TCP/TLS connection (id:
0) for WebSocket could not be found
 5(7435) ERROR: tm [t_msgbuilder.c:1367]: assemble_via: via building failed
