jnxSipCommonOptionTagTable
This table contains a list of the SIP option tags (SIP extensions) that 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 (IETF RFC 3262), this table contains a row with the option tag string '100rel' in jnxSipCommonOptionTag and the OCTET STRING value of '1010 0000' or '0xA0' in jnxSipCommonOptionTagHeaderField. 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).
