.SH "METHODS"
.IX Header "METHODS"
.IP "method" 4
.IX Item "method"
Get method of request.
.IP "uri" 4
.IX Item "uri"
Get \s-1URI\s0 part of request.
.IP "set_uri ( \s-1STRING\s0 )" 4
.IX Item "set_uri ( STRING )"
Set \s-1URI\s0 of request to \s-1STRING\s0
.IP "set_cseq ( \s-1NUMBER\s0 )" 4
.IX Item "set_cseq ( NUMBER )"
Set sequence number if \f(CW\*(C`CSeq\*(C'\fR header to \s-1NUMBER\s0.
.IP "create_ack ( \s-1RESPONSE\s0 )" 4
.IX Item "create_ack ( RESPONSE )"
Returns Net::SIP::Request object for \s-1ACK\s0 request for the case
when Net::SIP::Response \s-1RESPONSE\s0 was received in reply for packet \f(CW$self\fR.
.IP "create_cancel" 4
.IX Item "create_cancel"
Returns Net::SIP::Request object to cancel request in \f(CW$self\fR.
.IP "create_response ( \s-1CODE\s0, [\s-1MSG\s0,] [ \e%HEADER, \s-1BODY\s0 ] )" 4
.IX Item "create_response ( CODE, [MSG,] [ %HEADER, BODY ] )"
Returns Net::SIP::Response packet for the received request \f(CW$self\fR with
numerical code \s-1CODE\s0 and text message \s-1MSG\s0. Header for the response will
be based on the request, but can be added or overridden using \e%HEADER.
If \s-1MSG\s0 is not given (e.g. argument is missing, second argument is \e%HEADER
already) a builtin message for the code will be used.
.Sp
For details to \e%HEADER and \s-1BODY\s0 see \fBnew_from_parts\fR in Net::SIP::Packet.
.IP "authorize ( \s-1RESPONSE\s0, \s-1AUTH\s0 )" 4
.IX Item "authorize ( RESPONSE, AUTH )"
Tries to authorize request \f(CW$self\fR based on the information in \s-1RESPONSE\s0
(a 401 or 407 \*(L"Authorization required\*(R" response) and \s-1AUTH\s0. \s-1AUTH\s0 is either
\&\f(CW\*(C`[ user,pass ]\*(C'\fR if a global authorization info exists for all realms or
\&\f(CW\*(C`{ realm1 => [ user1,pass1 ], realm2 => [ user2,pass2 ],... }\*(C'\fR if
different credentials are provided for different realms or a callback
\&\f(CW\*(C`callback(realm)\->[user,pass]\*(C'\fR.
The realms, for which authorization is needed, are read from \s-1RESPONSE\s0.
.Sp
The request \f(CW$self\fR is modified in-place. If a modification occurred, e.g.
if (parts of) the authorization requests could be resolved it will return
\&\s-1TRUE\s0, else \s-1FALSE\s0.
.Sp
Supports only \s-1RFC2617\s0 with md5 and empty qop or qop 'auth', not md5\-sess
or qop's like 'auth\-int'.
