Method and apparatus for mitigating network failures

A non-transitory machine-readable storage medium, comprising executable instructions, which when executed by a processing system including a processor, facilitate performance of operations, comprising:

• downgrading a first codec to a second codec for circuit switched communications responsive to a breakout gateway control function system receiving a notification of a failure notice of a telephone number mapping query for a communication request that includes the first codec;
• determining that packet-switched voice over long-term evolution communications is possible according to an originating party identifier of an originating communication device and a terminating party identifier of a terminating party communication device;
• upgrading the second codec back to the first codec responsive to the determination that the packet-switched voice over long-term evolution communications is possible;
• and
• initiating a communication session as a packet-switched communication voice over long-term evolution session between the originating communication device and the terminating party communication device responsive to the determination that the packet-switched voice over long-term evolution communications is possible.

A first network node, comprising:

• a processing system including a processor;
• and
• a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, comprising:
• downgrading a first codec to a second codec for circuit switched communications responsive to a breakout gateway control function system receiving a notification of a failure notice of a telephone number mapping query for a communication request, wherein the communication request includes the first codec, a terminating party identifier of a terminating party communication device, and an originating party identifier of an originating communication device;
• determining that packet-switched voice over long-term evolution communications is possible according to the originating party identifier of the originating communication device and the terminating party identifier of the terminating party communication device;
• upgrading the second codec back to the first codec responsive to the determination that the packet-switched voice over long-term evolution communications is possible;
• and
• initiating, by a second network node, a communication session as a packet-switched communication voice over long-term evolution session between the originating communication device and the terminating party communication device responsive to the determination that the packet-switched voice over long-term evolution communications is possible.
