In an example embodiment, a solution is provided that provides multiple call control service instances for each media server instance. When one of the call control service instances needs to be updated, the media server is instructed to direct newly received voice calls to another of the call control instances. The call control service instance to be updated remains operating normally until all voice calls handled by that call control service instance have ended naturally, but any new calls received during that time are directed to one of the other call control service instances. Only once all the voice calls handled by the call control service instance to be updated have ended is that call control service instance actually updated, without having had to disconnect a live call.

A system and a method for providing resiliency in a telephony communication system are provided. The method includes: obtaining resources that are available in a first data center; receiving, from a client, a request for accessing a first resource; transmitting, to the client, a first Uniform Resource Locator (URL) that includes information for facilitating a client access to the first resource in the first data center; when the first resource becomes unavailable in the first data center and available in a second data center, transmitting, to the second data center, a subscribe message for facilitating a client access to the first resource in the second data center; and when the client access to the first resource in the second data center is available, transmitting, to the client, a second URL that includes information for facilitating the client access to the first resource in the second data center.

A method for improving a transcription may include identifying, in the transcription, reliable channel tokens of an utterance of a reliable channel and an unreliable channel token of an utterance of an unreliable channel, and generating, using a machine learning model, a vector embedding for the unreliable channel token and vector embeddings for the reliable channel tokens. The method may further include calculating vector distances between the vector embedding and the vector embeddings, and generating, for the unreliable channel token and using the vector distances, a score corresponding to a reliable channel token. The method may further include determining that the score is within a threshold score, and in response to determining that the score is within the threshold score, replacing, in the transcription, the unreliable channel token with the reliable channel token.

A system and a method for providing resiliency in a telephony communication system are provided. The method includes: receiving registration information that relates to a requested service, the registration information including a service name, a resource identifier such as a directory number, at least one pool, and status information; and mapping the received registration information to a database that associates the name of the requested service with the resource identifier and each pool and associates each pool with the status information; and transmitting at least two Uniform Resource Locators (URLs), including a primary URL and a backup URL, for providing the requested service.
