SIP over WebSocket appears to disconnect every 15 minutes

Hello, we are currently evaluating Baresip for use in a product, and we have run into an issue where the SIP Websocket connection disconnects every 15 minutes.

After experimenting with a variety of configurations and performing a tcpdump, we suspect there may be an issue in libre - specifically the TCP Idle Timeout timer in sip/transp.c:1074 never seems to be reset. Maybe I am missing something, but it seems to me that this is supposed to be reset by the conn_keepalive_handler, but that is never started when the SIP transport is set to WS or WSS in sip/keepalive.c (Also even if you enable it for WS/WSS, it's dependent on outbound being configured, and requires server re-configuration...)

I believe this can be patched by resetting the timer in the websock_recv_handler similar to how it is reset in the tcp_recv_handler, or alternatively just disabling the original timer, since the Websocket has its own keepalive.

Please correct me if I am missing something. Thank you.

Can you try #1075?

Should we fix this for v3.10?

Thank you for the prompt response.

I am testing with the branch now.
