Introduction to the SPA9000 Voice System
The SPA9000 Voice System is an affordable and feature-rich IP telephone system that is designed especially for the Small and Home Office. The SPA9000 Voice System uses standard TCP/IP protocols and can provide global connectivity through any Internet Telephony Service Provider (ITSP) that supports the Session Initiation Protocol (SIP).
At minimum, the SPA9000 Voice System includes a SPA9000 IP PBX and one or more SPA900 series IP phones. These devices are connected through a switch to a local area network. With an Internet connection, the SPA9000 Voice System can subscribe to ITSP services to take advantage of low calling rates. With the SPA400, the SPA9000 Voice System can connect to the Public Switched Telephone Network (PSTN) to support analog phone lines. See Figure 1 “SPA9000
Voice System with the SPA9000 and SPA400” on page14 to learn more about a
typical deployment.
Getting Started
Introduction to the SPA9000 Voice System
Figure1 SPA9000 Voice System with the SPA9000 and SPA400

SPA9000 IP PBX
The SPA9000 is an IP PBX that supports up to 16 phones. It also has a built-in Analog Telephone Adapter (ATA) with two FXS ports for analog telephones, fax devices, or an external music source for the music on-hold service. Devices connected to the FXS ports are not included in the device count.
The SPA9000 has four line interfaces, which can be configured in any combination for ITSP service, ISDN access, SPA400 PSTN access, or SPA400 voice mail service. A different ITSP account can be configured on each line interface. If a service provider supplies a group of sequential direct inward dial (DID) phone numbers (such as 408-555-0100 through 555-0145) the SPA9000 can support all of the assigned numbers on a single line interface.
Getting Started
Deployment Scenarios
1
The SPA9000 includes an Auto Attendant service that plays pre-recorded voice messages to offer the caller a menu of choices and to direct the call. When the Auto-Attendant is enabled, it parses and operates on user key presses according to the rules that are specified in the Auto Attendant script.
SPA400 SIP-PSTN Gateway and Voicemail Server
The SPA400 provides a SIP-PSTN gateway for voice connectivity between the PSTN and the local client stations that are connected to the SPA9000. It also includes an integrated voice mail application that supports up to 32 voice mail accounts with customized greetings, providing the ability to receive and playback voice mail messages.
Each SPA400 occupies one of the four line interfaces on the SPA9000. The SPA400 has four ports for that can be connected to PSTN or ISDN lines.
IP Phones and Accessories
The SPA9000 Voice System supports any of the Cisco SPA900 Series SIP IP Phones, as well as the Cisco WIP310 Wireless IP Phone.
NOTE This guide explains how to configure the SPA9000 and the SPA400 to support the
calling features on the phones. For more information about the phones, see the
SPA9x2 Phone Administration Guide, the SPA9x2 Phone User Guide, and the Cisco Wireless-G IP Phone User Guide.
Deployment Scenarios
The SPA9000 Voice System can meet the calling needs of many small businesses. Various deployment scenarios are possible. This section includes the following examples:
• “PSTN Access and Local Voice Mail,” on page16
• “ITSP Service Only,” on page17
• “ITSP Service, PSTN Access and Local Voice Mail,” on page18
• “ITSP Service, PSTN and ISDN Access and Local Voice Mail,” on page19
Getting Started
Deployment Scenarios
1
PSTN Access and Local Voice Mail
In this scenario, the customer requires a robust phone system but is not using VoIP services. The SPA9000 Voice System is deployed with a SPA9000 IP PBX, one SPA400 for PSTN access with four FXO ports, and another SPA400 for local voice mail service. Up to 16 IP phones can be installed. Optionally, analog phones or fax machines (not illustrated) can be connected to the two phone ports on the SPA9000.
Getting Started
Deployment Scenarios
1
ITSP Service Only
In this scenario, a customer has no legacy telephone numbers and either needs no voice mail at all or has voice mail hosted by the ITSP. The SPA9000 Voice System is deployed with the SPA9000 IP PB and VoIP service. Up to 16 IP phones can be installed. Optionally, analog phones or fax machines (not illustrated) can be connected to the two phone ports on the SPA9000.
Getting Started
Deployment Scenarios
1
ITSP Service, PSTN Access and Local Voice Mail
In this scenario, the customer wants to use ITSP service for reduced long distance fees but needs to support legacy local telephone numbers (for example, to receive calls to a legacy telephone number or to place outbound calls in the local area). This customer also prefers local voice mail service. The SPA9000 Voice System is deployed with the SPA9000 IP PBX, VoIP service, one SPA400 unit for voice mail service, and another SPA400 unit for PSTN access with four FXO ports. Up to 16 IP phones can be installed. Optionally, analog phones or fax machines (not illustrated) can be connected to the two phone ports on the SPA9000.
Getting Started
Deployment Scenarios
1
ITSP Service, PSTN and ISDN Access and Local Voice Mail
In this scenario, the customer takes full advantage of the SPA9000 Voice System solution. This customer has the SPA9000 IP PBX, VoIP service, one SPA400 unit for voice mail service, and another SPA400 for PSTN access with four FXO ports. In addition, this installation includes an ISDN Gateway for ISDN BRI access with four BRI ports. Up to 16 IP phones can be installed. Optionally, analog phones or fax machines (not illustrated) can be connected to the two phone ports on the SPA9000.
