Looking at the hex dump that you provided: It contains 43 bytes of FF, followed by the following text, followed by CR LF: X-BroadWorks-DNC: network-address="sip:+34937817016@mt;user=phone";user-id="937817...@mfe.telefonica.net" That text looks like a header that might be used in SIP requests. But it is a non-standard header, you can tell because it starts with "X-". It is probably defined by BroadWorks. Without knowing how BroadWorks has defined the header, and the operational environment in which it was used, there's no way to know whether it is valid.

Re: [Sip-implementors] RFC ABNF grammar check for Truncated unrecognized header
Rakesh, I still don't understand your question. What you show below appears to be garbage that happens to include a few fragments that resemble sip URIs. Did you receive this on a port where you expect to receive sip messages? If so, this clearly doesn't conform to the ABNF syntax of a sip message.

[Sip-implementors] RFC ABNF grammar check for Truncated unrecognized header
Hi Expert, Can I just know on INVITE request if I get the below characters then is it OK as per ABNF grammar? Please note I am not asking about the header rather I need to know the correctness of the character that has appeared on INVITE request.
