.SH DESCRIPTION
.sp
.LP
The \fBsip_add_request_line()\fR function adds a request line to the \fBSIP\fR
message \fIsip_request\fR. The request line is created using the \fBSIP\fR
method specified in \fImethod\fR and the \fBURI\fR in \fIrequest_uri\fR. The
\fBSIP\fR method can be one of the following:

The resulting request line has the \fBSIP\fR-Version of "2.0".

The \fBsip_add_response_line()\fR function adds a response line to the
\fBSIP\fR message \fIsip_response\fR. The response line is created using the
response code \fIresponse_code\fR and the phrase in \fIresponse_phrase\fR. If
the \fIresponse_code\fR is one that is listed in RFC 3261,
\fBsip_get_resp_desc()\fR can be used to get the response phase for the
\fIresponse_code\fR. The resulting response line has the \fBSIP\fR-Version of
"2.0".
.SH RETURN VALUES
.sp
.LP
The \fBsip_add_response_line()\fR and \fBsip_add_request_line()\fR functions

The value of \fBerrno\fR is not changed by these calls in the event of an
error.
