Cornfed SIP User Agent 1.1.7 (Default branch)
Image The Cornfed SIP User Agent is a Session Initiation Protocol (SIP)-based Softphone for x86 Linux systems running the GNOME Desktop environment. It allows you to make Internet phone calls using an Advanced Linux Sound Architecture (ALSA) or Open Sound System (OSS) sound card with speakers and microphone as your telephone handset. License: Free for non-commercial use Changes:
The Contact header address was changed to use registration user. A separate Expires header line was added to outbound REGISTER messages to address some Session Border Controllers (SBCs). A bug where compact forms of Contact and Via headers were not recognized in incoming messages was fixed. A bug introduced after 1.1.4 that prevents reset of expiration timer during re-registrations was fixed. A bug that prevented soundcard status from returning useful data was fixed. All SUBSCRIBE/NOTIFY implementation code was removed. A feature where .wav playback when no call is in progress is played out the speakers was added back. Image

sip_get_header

sip_get_header(3SIP)				   Session Initiation Protocol Library Functions			      sip_get_header(3SIP)

NAME

       sip_get_header - get a SIP header from a message

SYNOPSIS

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

       const struct sip_header *sip_get_header(sip_msg_t sip_msg,
	    char *header_name, sip_header_t old_header, int *error);

DESCRIPTION

       The  sip_get_header()  function	returns  the  header  specified  by  header_name  (long  or compact form) from the SIP message sip_msg. If
       header_name is NULL, the first header in the SIP message is returned. The old_header, if  non-null,  specifies  the  starting  position	in
       sip_msg	from  which the search is started. Otherwise, the search begins at the start of the SIP message. For example, to get the first VIA
       header from the SIP message sip_msg:

	 via_hdr = sip_get_header(sip_msg, "VIA", NULL, &error);

       To get the next VIA header from sip_msg:

	 via_hdr = sip_get_header(sip_msg, "VIA", via_hdr, &error);

       The sip_get_header() function ignores any header that is marked as deleted.

RETURN VALUES

       On success, the sip_get_header() function returns the queried header. On failure, it returns NULL.

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

ERRORS

       The following value may be returned:

       EINVAL	 The header_name specified in the SIP message is not present or has been deleted; or, the header_name is not specified	and  there
		 are no "un-deleted" headers in the SIP message.
