Description

Hello. Probably I'm doing something wrong but I can't get rid of received parameter in the Via header in responses from kamailio by websocket transport.

According RFC 7118:
When a SIP WebSocket Server receives a request, it MAY decide not to add a "received" parameter to the top Via header. Therefore, SIP WebSocket Clients MUST accept responses without such a parameter in the top Via header regardless of whether the **Via** "sent-by" field contains a domain name.

Expected behavior

For responses to websocket transport have a way to not add received parameter in Via header

Actual observed behavior

Responses to OPTION or REGISTER methods trough websocket got received containing IP we want to not show to the end users.

Possible Solutions

maybe add a param in tm module or something

Additional Information

Kamailio Version - output of kamailio -v

version: kamailio 5.2.1 (x86_64/linux)

and

kamailio 5.6.1 (x86_64/linux) b36a13
