</span>Hello Phillip,<br>
<br>
an in-dialog OPTIONS is not normal, it should be not required for the normal <br>
call-flow. I think the OPTIONS is indeed the event 8 here.<br>
<br>
You find the event definitions in dlg_hash.h in the dialog module:<br>
<br>
/* events for dialog processing */<br>
#define DLG_EVENT_TDEL 1 /*!< transaction was destroyed */<br>
#define DLG_EVENT_RPL1xx 2 /*!< 1xx request */<br>
#define DLG_EVENT_RPL2xx 3 /*!< 2xx request */<br>
#define DLG_EVENT_RPL3xx 4 /*!< 3xx request */<br>
#define DLG_EVENT_REQPRACK 5 /*!< PRACK request */<br>
#define DLG_EVENT_REQACK 6 /*!< ACK request */ <br>
#define DLG_EVENT_REQBYE 7 /*!< BYE request */ <br>
#define DLG_EVENT_REQ 8 /*!< other requests */<br>
<br>
You should ask the provider why they send you this OPTIONS here. But if your <br>
calls are not affected (which I assume) you could also ignore it.<br>
<br>
Best regards,<br>
<br>
Henning<br>
