Specifies the character set to be used to display the session name and
information data. By default, the ISO-10646
character set in UTF-8 encoding is used. If a more compact representation
is required, other character sets may be used
such as ISO-8859-1 for Northern European languages.
Specifies whether to try to write "typed-time" fields instead of raw integer

they may be
specified using logical units. From RFC 2327:
To make announcements more compact, times may also be given in units of
days, hours or minutes. The syntax for these is a number immediately
followed by a single case-sensitive character. Fractional units are not
allowed - a smaller unit should be used instead. The following unit
specification characters are allowed:
d - days (86400 seconds)
h - minutes (3600 seconds)
m - minutes (60 seconds)
s - seconds (allowed for completeness but not recommended)

Specifies whether to generate "a=rtpmap:" attributes for static RTP/AVP format strings.
This is recommended but makes messages bigger. The default is not to write such
flag if true "a=rtpmap:" attributes are generated for all "RTP/AVP" formats
