Cisco DPA Series Voice Mail Gateways
Cisco DPA 7610 and Cisco DPA 7630
The Cisco DPA Series of voice mail gateways is a family of Voice over IP (VoIP) gateways that enables legacy voicemail equipment to connect to a Cisco IP telephony solution network. The Cisco DPA Series allows Octel voice mail systems, which currently use Digital Station Emulation to connect to an Avaya Definity PBX, or a Nortel Meridian 1 PBX, to instead connect to a Cisco CallManager system without any changes to the voice mail system. The Cisco DPA Series allows the voice mail system to be used solely by the Cisco CallManager or to be shared between the Cisco CallManager and the private branch exchange (PBX).
The Cisco DPA Series communicates with the Cisco CallManager by emulating IP phones using an autosensing 10/100 Ethernet port. The Cisco DPA Series communicates with the PBX and voice mail system using 24, digital station lines. The Cisco DPA Series is easily configured using a simple menu system accessed with Telnet. The Cisco CallManager is easy to configure—it can even be done automatically using the auto registration feature. The CiscoDPA Series provides:
•Investment protection—The Cisco DPA Series allows the Octel voice mail system to be maintained without any hardware or software component changes.
•Seamless migration—Users can move from the PBX to Cisco CallManager without any changes to their voice mail box. They can maintain the same phone number and any messages they have saved will remain on the voice mail system.
•Gradual migration—The Cisco DPA Series allows both Cisco CallManager and the PBX to share the same Octel system, allowing you to gradually move users from the PBX to the Cisco CallManager.
•Feature preservation—All voice messaging features familiar to PBX users will also be available with the Cisco CallManager, such as the "spell by name" feature.

Enabled by Cisco AVVID (Architecture for Voice, Video and Integrated Data), the Cisco DPA Series provides the following:
•Easy installation—The Cisco DPA Series uses the same RJ-21 connectors as previous PBX systems, making it a simple task to replace PBX with a Cisco DPA Series at the punch-down block.
•Easy configuration—The Cisco DPA Series is easily configured using Telnet or a 9600-baud console port. It can use Dynamic Host Configuration Protocol (DHCP) to automatically obtain an IP address and can register the address with Cisco CallManager. Manual configuration is also possible.
•Manageability—The Cisco DPA Series is manageable using Telnet or Simple Network Management Protocol (SNMP). Through Telnet users can monitor the status of all the ports.
•Media flexibility—The Cisco DPA Series supports G.711 and G.729a voice codecs and fax for Octel-based fax mailboxes.
•Reliability—The Cisco DPA Series is a highly reliable, self-contained hardware device. It supports Cisco CallManager failover for resilience from server failures. If complete fault tolerance is required, two units can be used in parallel.
