Feature Benefits
Circuit Switched Leased Line Replacement
Businesses incur significant recurring monthly costs for leased lines purely for the
interconnection of telecom PBXs and switches. This product gives these enterprises the
ability to remove these costly rigid-bandwidth leased lines and replace them with flexible
bandwidth lines, which will be used to carry data, voice, and video. The ability to support
proprietary PBX signaling types exists by using connection trunking and transparent CCS.
Private Line Automatic Ringdown (PLAR)
Provides a direct connection to another digital or analog voice port by lifting a telephone
handset on one end.
H.323 Version 3 and 4 Support
Uses industry-standard signaling protocols for call setup between gateways, gatekeepers, and
H.323 end points (such as Intel Internet Phone or Microsoft Netmeeting).
DTMF Relay
Carries DTMF tones/information out-of-band for clearer transmission and detection.
Authentication, Authorization, and Accounting
(AAA)
Supports debit and credit card (prepaid and post-paid calling card) applications.
Interactive Voice Response Support (IVR)
Utilizes IVR to provide automated-attendant, voice-mail support, and call routing based on
desired service.
Open Settlement Protocol Support (OSP)
Provides the ability to settle account billing between service providers who are sharing
resources to expand geographical coverage using third-party tools and standards-based OSP.
Any Call to Any Call with End-to-End
Interoperability
Interoperates with Cisco IP phones, analog phones, fax machine connections, and PBX
connections to and from any other Cisco voice enabled product.
Gateway for Legacy PBXs, Phones, Fax
Machines, and Key Communication Systems
to PSTN
Enables a connection for incoming and outgoing calls to and from the PSTN originating
from and destined for legacy PBXs, phones, fax machines, and key communication systems
connected to a data, voice, and video infrastructure.
Integrated Add/Drop Multiplexer
Performs add/drop multiplexing for voice within a dual-port voice Network Module.
Eliminates the requirement, maintenance, support, and expense found when using an
external add/drop multiplexer.
AVVID Interoperable
Interoperable within Cisco’s AVVID architecture.
Call Control Signaling
Supports H.323 v3/v4, MGCP, and SIP call control protocols.
Gateway for IP phones to PSTN or Classic
