hello there..
this could seem easy but i just cant see it..
im trying to retrieve and rtsp url that is in a sip invite message
header, on content_type section of the header.. like this:
SIP/2.0 200 OK
Via: SIP/2.0/UDP
192.168.0.110:51458;rport=51458;branch=z9hG4bKDrt305Hmycr8H
Record-Route: <sip:m...@scscf.open-ims.test:6060;lr>
Record-Route: <sip:m...@pcscf.open-ims.test:4060;lr>
From: <sip:b...@open-ims.test>;tag=BX8rFa5N6v9BS
To: <sip:chann...@iptv.open-ims.test>;tag=1265391275

im trying to get the content type on the callback of the event
nua_r_invite with this:
void app_r_invite(int status, char const *phrase,
nua_t *nua, cliente *cli,
nua_handle_t *nh, sip_t const *sip,
tagi_t tags[])
{
printf(": INVITE : %03d %s\n", status, phrase);
if (!sip) {
printf(": NOTIFY sip=%p,nh=%p\n", sip, nh);
return;
}
if ( status == 200 )
{
if(sip)
{
char *header;
header = sip_header_as_string( cli->home, (void*)
sip->sip_content_type);
printf("\nCONTENT TYPE -> %s\n", header);
}
but i just keep getting :
INVITE : 200 OK
CONTENT TYPE -> (null)
can anyone help please? Where should i get the content_type and how?
Miguel
