Hi everybody!
Fisrt I want to thank you developers for your excelent work on this SIP
framework, But as you sure can guess, I have a problem.
I am using sofia sip to get notified when a busy callee is ready again, using a
SUBSCRIBE for a dialog event.
The first SUBSCRIBE works perfectly, I get a NOTIFY "confirmed" for subscribing
and the NOTIFY "terminate" from the callee, when the current call has ended.
However when I want to unsubscribe i get error 404 from the callee.
It seems that the user of the SUBSCRIBE Request is missing. It should be
"sip:test@192.168.90.100" but only "sip:192.168.90.100" is sent on the
SUBSCRIBE with expire 0.
code looks like this:
case nua_i_notify:
printf("Notify received, status: %d, %s\n", status, phrase);
state_start = 0;
state_end = 0;
state_start = strstr(sip->sip_payload->pl_data, "<state>");
state_end = strstr(sip->sip_payload->pl_data, "</state>");
if((state_start) && (state_end))
{
state_start += 7; // start after <state>
strncpy_s(state, sizeof(state), state_start, state_end -
state_start);
printf("state changed to %s\n",state);
if (!strcmp(state, "terminated"))
{
nua_unsubscribe(nh, SIPTAG_EVENT_STR("dialog"),
TAG_END());
Is it necessary to make a new nua_handle for the unsubscribe.
When is it necessary to genereate a new handle for operations?
Kind regards
