<div class="im">> i use the dialog module.<br>> i create the dialog using dlg_manage() right after the invite is recieved.<br>> in a case where the final destination rejects the call (486 busy), i get the following error:<br>

<br></div>No, the module shouldn't behave like that. IIRC, a terminating dialog is tied to its underlying transaction and should stay alive until the transaction times out.<br><br>Does each ACK message include a proper dialog ID (i.e., To-tag, From-tag, and Call-ID corresponding to the 486 message)? Is the ACK routed statefully at all?<br>
