Secure Voice Overview | AT&T Office@Hand
AT&T Office@Hand for has implemented a number of server side upgrades to improve the service for our small business and enterprise customers. Some of these changes affect how endpoints (e.g. desktop IP phones, conferencing phones, Analog Terminal Adapters (ATAs), soft phones, and mobile applications) will communicate with the AT&T Office@Hand cloud servers as we roll out these capabilities to our customers. These upgrades were necessary to provide a number of immediate and future benefits including improved signaling reliability, more robust network security, and improved efficiencies in how endpoint devices register and communicate with the AT&T Office@Hand cloud servers.
