MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This table contains a list of the SIP option tags (SIP
extensions) that are either required, supported, or
unsupported by the SIP entity. These option tags are
used in the Require, Proxy-Require, Supported, and
Unsupported header fields.
Example: If a user agent client supports, and requires the
server to support, reliability of provisional responses
(RFC 3262), this table contains a row with the option tag string
'100rel' in sipCommonOptionTag and the OCTET STRING value of
'1010 0000' or '0xA0' in sipCommonOptionTagHeaderField.
If a server does not support the required feature (indicated in
a Require header to a UAS, or in a Proxy-Require to a Proxy
Server), the server returns a 420 Bad Extension listing the
feature in an Unsupported header.
Normally, the list of such features supported by an entity is
static (i.e., will not change over time)."

"RFC 3261, Sections 19.2, 20.32, 20.29, 20.37, and 20.40"
