javax.sip.header
Interface AcceptLanguageHeader

All Superinterfaces:

java.lang.Cloneable, Header, Parameters, java.io.Serializable

public interface AcceptLanguageHeader
extends Parameters, Header

The Accept-Language header field is used in requests to indicate the preferred languages for reason phrases, session descriptions, or status responses carried as message bodies in the response. If no Accept-Language header field is present, the server SHOULD assume all languages are acceptable to the client. The q-value is used in a similar manner to AcceptHeader to indicate degrees of preference.

For Example:
Accept-Language: da, en-gb;q=0.8, en;q=0.7
