Abstract
A session border controller (SBC) that is separate from a telephony server associated with a destination telephony address receives an initiation request for a telephone call from an originating telephony device to the destination telephony address. The SBC attempts to connect the originating telephony device to the telephony server. Upon failing to connect the originating telephony device to the telephony server, the SBC connects the originating telephony device to a backup address associated with a distribution group. The SBC causes connection of the telephony device to a device of the distribution group via the backup address.
Claims20
A method comprising:
- receiving, by a session border controller that is separate from a telephony server associated with a destination telephony address, an initiation request for a telephone call from an originating telephony device to the destination telephony address;
- attempting to connect the originating telephony device to the telephony server;
- upon failing to connect the originating telephony device to the telephony server, connecting the originating telephony device to a backup address associated with a distribution group;
- and
- causing connection of the telephony device to a device of the distribution group via the backup address.
A non-transitory computer readable medium storing instructions operable to cause one or more processors to perform operations comprising:
- receiving, by a session border controller that is separate from a telephony server associated with a destination telephony address, an initiation request for a telephone call from an originating telephony device to the destination telephony address;
- attempting to connect the originating telephony device to the telephony server;
- upon failing to connect the originating telephony device to the telephony server, connecting the originating telephony device to a backup address associated with a distribution group;
- and
- causing connection of the telephony device to a device of the distribution group via the backup address.
A system, comprising:
- a memory subsystem storing instructions;
- and
- processing circuitry configured to execute the instructions to:
- receive, by a session border controller that is separate from a telephony server associated with a destination telephony address, an initiation request for a telephone call from an originating telephony device to the destination telephony address;
- attempt to connect the originating telephony device to a telephony server associated with the destination telephony address;
- upon failing to connect the originating telephony device to the telephony server, connect the originating telephony device to a backup address associated with a survivable distribution group;
- and
- cause connection of the telephony device to a device of the survivable distribution group via the backup address.
