Re: [osip-dev] event for non-200 final response to INVITE.

Hi Joseph,

Hi Aymeric,

What event gets generated when an INVITE is finalized with a 6xx or 4xx final response?  That is, if i issue an INVITE request to an endpoint, and the endpoint issues a non-200 final response (i.e. 3xx, 4xx, 5xx, 6xx), what exOsip event is generated (CALL_GLOBALFAILURE or CALL_RELEASED)?

The events are detailled in file eXosip2\eXosip.h:

    EXOSIP_CALL_NOANSWER,          /**< announce no answer within the timeout */
-> this is when you don't receive any final answer

    EXOSIP_CALL_PROCEEDING,        /**< announce processing by a remote app   */
-> this is when receiving 100

    EXOSIP_CALL_RINGING,           /**< announce ringback                     */
-> this is when receiving 1xx

    EXOSIP_CALL_ANSWERED,          /**< announce start of call                */
-> this is when receiving 2xx

    EXOSIP_CALL_REDIRECTED,        /**< announce a redirection                */
-> this is when receiving 3xx

    EXOSIP_CALL_REQUESTFAILURE,    /**< announce a request failure            */
-> this is when receiving 4xx

    EXOSIP_CALL_SERVERFAILURE,     /**< announce a server failure             */
-> this is when receiving 5xx

    EXOSIP_CALL_GLOBALFAILURE,     /**< announce a global failure             */
-> this is when receiving 6xx

I'm doing my best to use the same wording as from the rfc3261!

EXOSIP_CALL_RELEASED will also be sent when the call context will be released: ie, if
you receive a 6xx, you will first receive EXOSIP_CALL_GLOBALFAILURE and then
a second event EXOSIP_CALL_RELEASED when all context can be enterely released.
(with various delay depending on sip timeout and implementation constraint)
