The problem is I can send any type of content I want as long as the first
byte is not 0x00 ... If this byte is 0x00 it will send a 0 byte SIP message
out. So for example here is a short message that works perfectly, If I
change the payload[0] = 0x02 line to payload[0] = 0x00 an empty Content
Length is generated ...
--
nua_handle_t *h;
static int lastSequenceNum = -1;
char payload[5];
payload[0] = 0x02;
payload[1] = 0x07;
payload[2] = 0x01;
payload[3] = gMOSMS_seqnum << 2;
payload[4] = '\0';
printf("smsagent: Sending L2-ACK with seq: %d \n", gMOSMS_seqnum );
if( lastSequenceNum == gMOSMS_seqnum)
{
printf("smsagent: duplicate seq: %d \n", gMOSMS_seqnum );
}
// send_3ggp2_sms(nua, payload );
h = nua_handle(nua, NULL, SIPTAG_TO_STR(gREMOTE_CLIENT_TAG), TAG_END() );
nua_message(h, SIPTAG_CONTENT_TYPE_STR("application/vnd.3gpp2.sms"),
SIPTAG_PAYLOAD_STR( payload ), TAG_END() );
nua_handle_destroy(h);

I guess I need to use a different macro that doesn't treat the payload as a
string or initialize an empty SIP message and cast the pl_data pointer to my
new message ? Should I just malloc() a bunch of bytes and assign this to
pl_data and set pl_en even so I'm still using the SIPTAG_PAYLOAD_STR()
macro so is there way of creating a nua_message where it will treat the
pl_data not as a string ?
thanks for replying!
