### 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](https://datatracker.ietf.org/doc/rfc7118/): `` 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 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3515 You are receiving this because you are subscribed to this thread.
