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.
