I'm not sure what you mean by "SIP ID". If you are referring to no user portion within a SIP-URI, it is valid. However, it might not produce the result they were expecting. The following thread discusses some RFC 3842 ambiguity concerning looking at To header's URI. https://lists.cs.columbia.edu/pipermail/sip-implementors/2009-April/022446.html If you are referring to no URI scheme, it is not valid. Request-URI = SIP-URI / SIPS-URI / absoluteURI absoluteURI = scheme ":" ( hier-part / opaque-part ) _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
