By default, intra-office users and QSIG trunk users have service rights of the callback on busy and callback on no reply services. To use the callback on busy or on no reply service across SIP trunks, SIP trunk users must enable the subscription support function of SIP trunks. By default, POTS users with normal, advanced, and super user rights can use the RCB service.
