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.
