# Assistant configuration The assistant allows to create a new sip account on a pre-defined SIP service using an xml-rpc connection, as well as configuring an existing SIP account. The files Resources/assistant_linphone_create.rc and Resources/assistant_linphone_existing.rc contain the information necessary to create and configure the SIP accounts, most notabily: * proxy_default_values/reg_identity to define the SIP identity * sip/rls_uri to define the SIP URI of the presence server * assistant/domain to specify the SIP domain * assistant/xmlrpc_url to specify the https url of the account creation service # In-app purchase configuration The Resources/linphonerc.factory, section [in_app_purchase] is the entry point for configuring the in-app purchases available in the application, as well as parameters for account expiry notifications. Refer to the inlined comments in this configuration for description of all configurables.
