IP Telephony Voice Gateway
• Integrates all Cisco IP Communications solutions by providing flexible and reliable connectivity to
public or private switched telephone networks around the world.
• Provides gateway for Cisco IP phones to PSTN or traditional PBXs and private automatic branch
exchanges (PABXs).
• Provides gateway to PSTN for traditional PBXs, phones, fax machines, and key communication
systems connected to a voice, data, and video infrastructure.
• Interoperable within Cisco AVVID and Cisco IP Communications solutions.
Toll Bypass
• Reduce or eliminate toll charges assessed by long distance and local carriers by transporting voice
and fax traffic across the enterprise intranet, LAN, metropolitan-area network (MAN), or WAN.
• Works with existing phones, faxes, PBXs, and key systems.
• Connection trunks creates a permanent tie-line replacement structure (digital-to-digital, digital-to-
analog, or analog-to-analog capabilities).
• Interoperates end-to-end with Cisco IP phones, analog phones, fax machine connections, and PBX
or PABX connections to and from other Cisco voice enabled products.
