Dear all, I would like to change some settings of a registered account, like "register timeout". For that I call pjsua_acc_modify function with the unmodified and new settings. For some settings, the pjsua_acc_set_registration is automatically called but for other settings (like "register timeout") the pjsua_acc_set_registration function has to be manually called. Unfortunately, the new settings are not taken into account during the new registration, because the regc (field of the pjsua_acc structure) is not NULL. And in this case, the register message header is not rebuilt (like Expires header), because the pjsua_regc_init function is not called. How can I change some settings of a registered account (like register timeout) without unregister and register the account ? Regards Samuel
