Hi, I have a question more in a general aspect. Since the draft-levy-sip-diversion-08 has expired, should a Proxy strip such headers? According to RFC3261,the UAS MUST ignore headers-fields not defined in the specification or any supported extension... I've realized that some systems need Diversion headers for voicemail (I know Asterisk doesn't, but Cisco Unity does) Any comments? -- Helge Waastad Senior Engineer Systemavdelingen Smartnet
