Spa8800 Gateway - Cisco IE-3000-8TC Administration Manual

Components of the Cisco Business Edition 3000 System
Inbound and Outbound Called Party and Calling Party Transformations
Administrators can add or edit transformation patterns through the Cisco Business Edition 3000 Administrative
Interface. Administrators can set digit discard instructions from the Outbound Call Routing section that appears
under Advanced Settings in order to transform called party numbers for each PSTN connection. Digit discard
instructions allow you to manipulate dialed digits or called party number for outgoing calls by appending or
removing prefix digits. The default digit discard instructions at the egress connection down-size the called
party number to contain the subscriber digits only. For outbound call routing to function properly, the called
party number is up-sized based on the calling party location and routed based on class of service. The called
party number is down-sized at the gateway egress.
Different service providers may use a different number of digits for the called number. For example, a service
provider in North America may expect 11 digits for a local call and 8 digits for an international call. To support
advanced routing cases, Cisco Business Edition 3000 allows you to customize called party transformation
patterns for each connection.
To route inbound calls to your internal extensions, you must remove the significant digits at the ingress gateway
and append prefix digits to match the resulting number to an extension. By default, the significant digits that
are retained in the calling party number is set to be equal to extension length and no prefix digits are added.
To customize inbound call routing, Cisco Business Edition 3000 allows you to alter the significant digits and
prefix digits for each connection.
You can edit the called party transformation and the calling party transformation patterns while configuring
or editing the PSTN connection using the Cisco Business Edition 3000 Administrative Interface.

SPA8800 Gateway

SPA8800 is a small business analog gateway that supports the following functionality:
• Analog trunking (FXO) to the PSTN
• Devices such as analog phones and fax machines
Cisco Business Edition 3000 is not responsible for upgrading SPA8800 firmware. Therefore, users must
upgrade SPA8800 to the latest firmware (version 6.1.7 or later) prior to setting up analog trunks and lines on
the Cisco Business Edition 3000. Firmware can be downloaded from
callcontrol/cmbe/3000/index.shtml.
