Dan i'm little confusing for you proposition to using module.
Before sending signalling packet on_tx_request gives me pjsip_tx_data *tdata structure. Inside there i find only one member, which i think i can using pjsip_msg *msg;
but there is i can change body only, but not headers.
Simply enumeration:
const pjsip_hdr *h;
unsigned cnt = 0;
h = tdata->msg->hdr.next;
while (h != &tdata->msg->hdr) {
++cnt;
h = h->next;
PJ_LOG(1,(THIS_FILE, "proxy_on_tx_request hsrc.name->%s hsrc.sname->%s", h->name.ptr,h->sname.ptr));
}
Show me only header attrubutes, but not values inside.
I didn't find possibility to change final sip message there, all buffers (pjsip_buffer) empty there.
Thank you for u future helps,
Alex.
