NAME

       sip_create_OKack - create an ACK request for a final response

SYNOPSIS

       cc [ flag ... ] file ... -lsip [ library ... ]
       #include <sip.h>

       int sip_create_OKack(sip_msg_t response,
	    sip_msg_t ack_msg, char *transport,
	    char *sent_by, int sent_by_port,
	    char *via_params);

DESCRIPTION

       The  sip_create_OKack() function constructs an ACK request in ack_msg for the final 2XX SIP response. The request line is created using the
       URI in the CONTACT header from the response. The SIP-Version in the request line is "2.0". The VIA header for the ACK  request  is  created
       using  transport,  sent_by,  sent_by_port  (if  non-zero),  and	via_params (if non-null). The following headers are copied to ack_msg from
       response:
	 FROM
	 TO
	 CALL-ID
	 MAX_FORWARDS

       The CSEQ header is created using the method as ACK and the sequence number from the CSEQ header in response.

RETURN VALUES

       The sip_create_OKack() function returns 0 on success and the appropriate error value in case of failure.

       The value of errno is not changed by these calls in the event of an error.

ERRORS

       On failure, the sip_create_OKack() function could return one of the following errors:

       EINVAL	  If mandatory input is not provided or if the input is invalid.

		  The sip_create_OKack() function can return this error if it does not find a CONTACT header or if it is unable to obtain the  URI
		  from the CONTACT header for the request line.

       ENOTSUP	  If the input SIP message cannot be modified.

       ENOMEM	  If memory allocation fails when creating the request/response line or when creating headers in the ACK request.

NAME

       sip_sendmsg - send an outbound SIP message to the SIP stack for processing

SYNOPSIS

       cc [ flag ... ] file ... -lsip [ library ... ]
       #include <sip.h>

       int sip_sendmsg(sip_conn_object_t obj, sip_msg_t sip_msg,
	    sip_dialog_t dialog, uint32_t flags);

DESCRIPTION

       The  sip_sendmsg()  function is used to send an outbound SIP message sip_msg to the SIP stack on its way to the peer. The connection object
       for the SIP message is passed as obj. The caller also provides the dialog associated with the message, if one exists. The value of flags is
       the result of ORing the following, as required:

       SIP_SEND_STATEFUL     Send  the	request  or response statefully. This results in the stack creating and maintaining a transaction for this
			     request/response. If this flag is not set transactions are not created for the request/response.

       SIP_DIALOG_ON_FORK    When this flag is set, the stack may create multiple dialogs for a dialog completing response. This may result due to
			     forking of the dialog creating request. If this flag is not set, the first response to a dialog creating request cre-
			     ates a dialog, but subsequent ones do not. It is only meaningful if the stack is configured to maintain dialogs.

RETURN VALUES

       The sip_sendmsg() function returns 0 on success and the appropriate error on failure.

       The value of errno is not changed by these calls in the event of an error.

ERRORS

       The sip_sendmsg() function can return one of the following errors on failure:

       EINVAL	 If a message is being statefully sent and the branchid in the VIA header does not conform to RFC  3261  or  when  accessing  CSEQ
		 header while creating a transaction.

       ENOENT	 If a message is being statefully sent, error getting the CSEQ header while creating a transaction.

       EPROTO	 If a message is being statefully sent, error getting the CSEQ value while creating a transaction.

       ENOMEM	 If  the  message  is  being  statefully  sent, error allocating memory for creating or adding a transaction or during transaction
		 related processing.
