hi, I have some doubts regarding feature tags registered through rfc 3840.
Feature tag values can be grouped into five categories. 1) Booleans 2) Numerical 3) Tokens 4) Comma separated tokens 5) string. Being a proxy server: 1) Booleans can take either "true" or "false". So, if a proxy server receives a request with feature value other than these two, what proxy server should do? Should reject with "400 bad request" or simply process what ever comes in ( as mentioned in rfc 3841 that proxy does not have to know anything about the meaning of the feature tags that it is comparing in order to perform the "matching algorithm)? As it is boolean and future rfc can not add any more values to boolean tags, can we reject with "400 Bad request"?. 2 There are some feature tags which takes tokens( ex: CLASS feature tag takes "business" and "personal") as values. Is it possible that future rfcs add feature values to this type of feature tags? If not, can we reject with "400 Bad request", if feature value is other than these tokens? Thanks in advance. pavan _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
