Hi Anthony,
According to RFC3261 and RFC 2543, Double quote "" is not mandatory. But I have seen it in some debug traces from other SoftPhones.
Ref: Section 20.39 of RFC 3261
I am no RFC lawyer, but inter alia, that out refers to RFC 2616, and the relevant part is the description of 'tokens' in a 'field', and when certain separaters are present, must be protected in a QUOTE form http://www.ietf.org/rfc/rfc2616.txt at section 2.2 Many HTTP/1.1 header field values consist of words separated by LWS or special characters. These special characters MUST be in a quoted string to be used within a parameter value (as defined in section 3.6). token = 1*<any CHAR except CTLs or separators> separators = "(" | ")" | "<" | ">" | "@" | "," | ";" | ":" | "\" | <"> | "/" | "[" | "]" | "?" | "=" | "{" | "}" | SP | HT --------------------------- Your target string as indicated by the error message in the first post was: To: sip:1000@66.220.15.234 <sip:1000@66.220.15.234> and the relevant unprotected section: sip:1000@66.220.15.234 contains: ":" and "@" without such quotation. I see Brian mentioned one, but it looks as though two are required to be protected A proper line might look like: To: "sip:1000@66.220.15.234" <sip:1000@66.220.15.234> -- Russ herrold
