I am using AMI to originate
Action: Originate
Channel: SIP/5511996175361@UPVOX
Context: FD_106_010_INICIO
Earlymedia: 1
ActionID: CALL_42240
Exten: s
Priority: 1
Async: 1
Timeout: 55000
Context FD_106_010_INICIO starts an FASTAGI program which starts an app
that just waits for* f->subclass.integer == AST_CONTROL_ANSWER*
if (f->frametype == AST_FRAME_CONTROL) {
if (f->subclass.integer == AST_CONTROL_ANSWER) {
ast_frfree(f);
break;
}
}
If I issue a *hangup request* on that channel, follow is *true*!
if (!(f = ast_read(chan))) {
break;
}
But looking at SNGREP the call is in SETUP.
I changed sip_hangup to inspect values
ast_verb(3, "************** HANGUP 14.1 %d < % d - %d != %d \n",
p->invitestate,INV_COMPLETED,ast_channel_state(p->owner),AST_STATE_UP);
and *ast_channel_state(p->owner) was equal to AST_STATE_UP*
This avoids *needcancel = TRUE* and therefore SIP doesn't send a CANCEL to
SIP PROVIDER
For tests only, I removed the check over channel state and CANCEL have been
sent to SIP PROVIDER.
Atenciosamente,
