(soon to e: TCP/TLS?)socket socket to use for listening to UDP sip messages.port the listening port for masquerading.void eXosip_set_user_agent( const char * user_agent )Set the SIP UserAgent: header string.Parameters:user_agent the UserAgent header to insert in messages.void eXosip_enable_ipv6( int ipv6_enable )Use IPv6 instead of IPv4.Parameters:ipv6_enable This paramter should be set to 1 to enable IPv6 mode.voideXosip_masquerade_contact(constchar * public_address,int port)This method is used to replace contact address with the public address of your NAT. The ipaddress should be retreived manually (fixed IP address) or with STUN. This address will onlybe used when the remote correspondant appears to be on an DIFFERENT LAN.Parameters:public_address the ip address.port the port for masquerading.If set to NULL, then the local ip address will be guessed automatically (returns to defaultmode). eXosip2 network API Functionsint eXosip_transport_set (osip_message_t *msg, const char *transport)int eXosip_guess_localip (int family, char *address, int size) Function DocumentationinteXosip_transport_set(osip_message_t * msg,const char*transport)Modify the transport protocol used to send SIP message.Parameters:msg The SIP message to modifytransport transport protocol to use (UDP, TCP or TLS)inteXosip_guess_localip( intfamily,char*address,int size)Find the current localip (interface with default route).Parameters:family AF_INET or AF_INET6address a string containing the local IP address.size The size of the string eXosip2 event API Data Structuresstruct eXosip_eventstruct eXosip_event Enumerationsenum eXosip_event_type {EXOSIP_REGISTRATION_NEW,EXOSIP_REGISTRATION_SUCCESS,EXOSIP_REGISTRATION_FAILURE,EXOSIP_REGISTRATION_REFRESHED,EXOSIP_REGISTRATION_TERMINATED,EXOSIP_CALL_INVITE,EXOSIP_CALL_REINVITE,EXOSIP_CALL_NOANSWER,EXOSIP_CALL_PROCEEDING,EXOSIP_CALL_RINGING,EXOSIP_CALL_ANSWERED,EXOSIP_CALL_REDIRECTED,EXOSIP_CALL_REQUESTFAILURE,EXOSIP_CALL_SERVERFAILURE,EXOSIP_CALL_GLOBALFAILURE,EXOSIP_CALL_ACK,EXOSIP_CALL_CANCELLED,EXOSIP_CALL_TIMEOUT,EXOSIP_CALL_MESSAGE_NEW,EXOSIP_CALL_MESSAGE_PROCEEDING,EXOSIP_CALL_MESSAGE_ANSWERED,EXOSIP_CALL_MESSAGE_REDIRECTED,EXOSIP_CALL_MESSAGE_REQUESTFAILURE,EXOSIP_CALL_MESSAGE_SERVERFAILURE,EXOSIP_CALL_MESSAGE_GLOBALFAILURE,EXOSIP_CALL_CLOSED,EXOSIP_CALL_RELEASED,EXOSIP_MESSAGE_NEW,EXOSIP_MESSAGE_PROCEEDING,EXOSIP_MESSAGE_ANSWERED,EXOSIP_MESSAGE_REDIRECTED,EXOSIP_MESSAGE_REQUESTFAILURE,EXOSIP_MESSAGE_SERVERFAILURE,EXOSIP_MESSAGE_GLOBALFAILURE,EXOSIP_SUBSCRIPTION_UPDATE,EXOSIP_SUBSCRIPTION_CLOSED,EXOSIP_SUBSCRIPTION_NOANSWER,EXOSIP_SUBSCRIPTION_PROCEEDING,EXOSIP_SUBSCRIPTION_ANSWERED,EXOSIP_SUBSCRIPTION_REDIRECTED,EXOSIP_SUBSCRIPTION_REQUESTFAILURE,EXOSIP_SUBSCRIPTION_SERVERFAILURE,EXOSIP_SUBSCRIPTION_GLOBALFAILURE,EXOSIP_SUBSCRIPTION_NOTIFY,EXOSIP_SUBSCRIPTION_RELEASED,EXOSIP_IN_SUBSCRIPTION_NEW,EXOSIP_IN_SUBSCRIPTION_RELEASED,EXOSIP_NOTIFICATION_NOANSWER,EXOSIP_NOTIFICATION_PROCEEDING,EXOSIP_NOTIFICATION_ANSWERED,EXOSIP_NOTIFICATION_REDIRECTED,EXOSIP_NOTIFICATION_REQUESTFAILURE,EXOSIP_NOTIFICATION_SERVERFAILURE,EXOSIP_NOTIFICATION_GLOBALFAILURE,EXOSIP_EVENT_COUNT} Functionsvoid eXosip_event_free (eXosip_event_t *je)eXosip_event_t * eXosip_event_wait (int tv_s, int tv_ms)eXosip_event_t * eXosip_event_get (void) Enumeration Type Documentationenum eXosip_event_typeStructure for event type descriptionEnumerator:EXOSIP_REGISTRATION_NEW announce new registration.EXOSIP_REGISTRATION_SUCCESS user is successfully registred.EXOSIP_REGISTRATION_FAILURE user is not registred.EXOSIP_REGISTRATION_REFRESHED registration has been refreshed.EXOSIP_REGISTRATION_TERMINATED UA is not registred any more.EXOSIP_CALL_INVITE announce a new callEXOSIP_CALL_REINVITE announce a new INVITE withincallEXOSIP_CALL_NOANSWER announce no answer within thetimeoutEXOSIP_CALL_PROCEEDING announce processing by aremote appEXOSIP_CALL_RINGING announce ringbackEXOSIP_CALL_ANSWERED announce start of callEXOSIP_CALL_REDIRECTED announce a redirectionEXOSIP_CALL_REQUESTFAILURE announce a request failureEXOSIP_CALL_SERVERFAILURE announce a server failureEXOSIP_CALL_GLOBALFAILURE announce a global failureEXOSIP_CALL_ACK ACK received for 200ok toINVITEEXOSIP_CALL_CANCELLED announce that call has beencancelledEXOSIP_CALL_TIMEOUT announce that call has failedEXOSIP_CALL_MESSAGE_NEW announce new ining request.EXOSIP_CALL_MESSAGE_PROCEEDING announce a 1xx for request.EXOSIP_CALL_MESSAGE_ANSWERED announce a 200okEXOSIP_CALL_MESSAGE_REDIRECTED announce a failure.EXOSIP_CALL_MESSAGE_REQUESTFAILURE announce a failure.EXOSIP_CALL_MESSAGE_SERVERFAILURE announce a failure.EXOSIP_CALL_MESSAGE_GLOBALFAILURE announce a failure.EXOSIP_CALL_CLOSED a BYE was received for this callEXOSIP_CALL_RELEASED call context is cleared.EXOSIP_MESSAGE_NEW announce new ining request.EXOSIP_MESSAGE_PROCEEDING announce a 1xx for request.EXOSIP_MESSAGE_ANSWERED announce a 200okEXOSIP_MESSAGE_REDIRECTED announce a failure.EXOSIP_MESSAGE_REQUESTFAILURE announce a failure.EXOSIP_MESSAGE_SERVERFAILURE announce a failure.EXOSIP_MESSAGE_GLOBALFAILURE announce a failure.EXOSIP_SUBSCRIPTION_UPDATE announce iningSUBSCRIBE.EXOSIP_SUBSCRIPTION_CLOSED announce end of subs
