[sr-dev] Re: [kamailio/kamailio] Missing from: tag creates ERROR: log (Issue #3399)

Just to add the next section from the RFC as well: ``` This is to maintain backwards compatibility with [RFC 2543], which did not mandate From tags. ``` Kamailio is not compatible with SIP 1.0, RFC 2543. The addition of a From tag is mandatory according to RFC 3261, [8.1.1.3](https://www.rfc-editor.org/rfc/rfc3261#section-8.1.1.3): ``` The From field MUST contain a new "tag" parameter, chosen by the UAC. ``` I think the standard is pretty clear that its mandatory in the scope of RFC 3261. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3399#issuecomment-1478189612 You are receiving this because you are subscribed to this thread.
