Deployment and Provisioning Overview
Cisco ATA 191 and 192 Analog Telephone Adapters (ATA) are intended for high-volume deployments by VoIP service providers to residential and small business customers. In business or enterprise environments, these ATAs can serve as terminal nodes. These devices are widely distributed across the Internet, connected through routers and firewalls at the customer premises.
The ATA can be used as a remote extension of the service provider back-end equipment. Remote management and configuration ensures the proper operation of the IP Telephony device at the customer premises.
This customized, ongoing configuration is supported by the following features:
-
Reliable remote control of the endpoint
-
Encryption of the communication controlling the endpoint
-
Streamlined endpoint account binding
Phones can be provisioned to download configuration profiles or updated firmware from a remote server. Downloads can happen when the phones are connected to a network, when they are powered up, and at set intervals. Provisioning is typically part of high-volume, Voice-over-IP (VoIP) deployments common to service providers. Configuration profiles or updated firmware are transferred to the device using TFTP, HTTP, or HTTPS.
-
If the phone is not yet configured, the provisioning server information is applied to the phone via one of the following options: -
Downloaded from the Cisco EDOS RC server via HTTPS.
-
Queried from the local DHCP server.
-
Entered via the Cisco phone web based configuration utility.
-
-
The phone downloads and applies the configuration XML via HTTPS, HTTP, or TFTP using provisioning server information.
-
The phone downloads and applies the updated firmware, if needed, via HTTPS, HTTP, or TFTP.
-
The VOIP service establishes using the specified configuration and firmware.
In this document, the terms phone and device mean the ATA.
