1228 Generating the Request
来源:互联网 发布:ubuntu安装分区教程 编辑:程序博客网 时间:2024/05/22 16:51
A valid SIP request formulated by a UAC MUST, at a minimum, contain
the following header fields: To, From, CSeq, Call-ID, Max-Forwards,
and Via; all of these header fields are mandatory in all SIP
requests. These six header fields are the fundamental building
blocks of a SIP message, as they jointly provide for most of the
critical message routing services including the addressing of
messages, the routing of responses, limiting message propagation,
ordering of messages, and the unique identification of transactions.
These header fields are in addition to the mandatory request line,
which contains the method, Request-URI, and SIP version.
The initial Request-URI of the message SHOULD be set to the value of
the URI in the To field.
In some special circumstances, the presence of a pre-existing route
set can affect the Request-URI of the message. A pre-existing route
set is an ordered set of URIs that identify a chain of servers, to
which a UAC will send outgoing requests that are outside of a dialog.
Commonly, they are configured on the UA by a user or service provider
manually, or through some other non-SIP mechanism. When a provider
wishes to configure a UA with an outbound proxy, it is RECOMMENDED
that this be done by providing it with a pre-existing route set with
a single URI, that of the outbound proxy.
