Accept: application/sdp;level=1, application/x-private, text/html
Accept Encoding This header identifies the method of encoding used for the ACCEPT
header, if encoding is used. It identifies the method by which the receiving endpoint
should decode any provided content in place of the SDP.
If the SDP is part of the message, the encoding method is contained within the SDP.
However, the ACCEPT and ACCEPT-ENCODING can be provided as part of a response
without using the SDP, identifying what the endpoint is able to support. One example
of this usage is within the 415 Unsupported Media Type response.
ACCEPT ENCODING: gzip
Accept Language This header is used to indicate when a language other than English is
being used in the status codes, SDP, or status responses. It is usually used in conjunction
70 Chapter 3
with the ACCEPT and ACCEPT-ENCODING headers. The default language is always
English unless otherwise noted with this header.
ACCEPT LANGUAGE: da, en-gb;q=0.8

indicate an alternative ringback tone.
