A system that incorporates the subject disclosure may perform, for example, operations including receiving a request from a communication device to initiate a communication session, obtaining a first name authority pointer (NAPTR) record that replaces a second NAPTR record responsive to an undesirable fault level in a voice over long term evolution (VoLTE) network, obtaining the second NAPTR record responsive to determining that there is no fault or a tolerable level of faults in the VoLTE network, and initiating the communication session according to one of the first NAPTR record or the second NAPTR record obtained by the system. The first NAPTR record can include instructions for initiating the communication session utilizing a circuit-switched communication network, and the second NAPTR record can include instructions for initiating the communication session utilizing the VoLTE network. Other embodiments are disclosed.
