Hi Iñaki, The custom headers are of interest to particular implementation. It depends on how you interpret multiple custom header line with same header name. if you process like list, it would be similar to list else overwritten with last header value. AFAIK, 3261 does not mandate on custom headers.
It would never be an issue for any intermediary entities, since they just relay as it is or drop it completely based on the role they play (proxy, b2bua, ...)
