How-To send or update registrations.(3) libeXosip2 How-To send or update registrations.(3)NAMEHow-To send or update registrations. - eXosip2 offers a flexible API to help you to register one or several identities. Initiate a registration To start a registration, you need to build a default REGISTER request bby providing several mandatory headers osip_message_t *reg = NULL; int id; int i; eXosip_lock (); id = eXosip_register_build_initial_register (identity, registrar, NULL, 1800, ®); if (id < 0) { eXosip_unlock (); return -1; } osip_message_set_supported (reg, '100rel'); osip_message_set_supported(reg, 'path'); i = eXosip_register_send_register (id, reg); eXosip_unlock (); return i; The returned element of eXosip_register_build_initial_register is the registration identifier that you can use to update your registration. In future events about this registration, you'll see that registration identifier when applicable. Update a registration You just need to reuse the registration identifier: int i; eXosip_lock (); i = eXosip_register_build_register (id, 1800, ®); if (i < 0) { eXosip_unlock (); return -1; } eXosip_register_send_register (id, reg); eXosip_unlock (); Note: The above code also shows that the stack is sometimes able to build and send a default SIP messages with only one API call Closing the registration A softphone should delete its registration on the SIP server when terminating. To do so, you have to send a REGISTER request with the expires header set to value '0'. The same code as for updating a registration is used with 0 instead of 1800 for the expiration delay.
