IP Telephony Media Gateways

Field-Proven Voice Quality over TDM and IP Networks

The I-Gate 4000 Media Gateways have been deployed by hundreds of carriers in more than 100 countries for voice, fax, modem, video, and

signaling traffic. The I-Gate 4000 Media Gateways enable carriers to bridge the gap between circuit-switched and next-generation Voice-over-IP

(VoIP) networks by delivering industry standard quality packet voice.

Bandwidth Savings without Compromising Voice Quality

Field-proven voice processing technology and advanced codec implementations, coupled with a rich set of bandwidth optimization and voice

quality protection techniques, enable carriers to realize bandwidth savings of up to 16:1 with I-Gate 4000 Media Gateways.

Bandwidth-Efficient and Reliable Signaling Transport

The unmatched ability of I-Gate 4000 Media Gateways to support bandwidth-efficient and reliable transport of Common Channel Signaling

(CCS) for SS7, PRI, and QSIG and Channel Associated Signaling (CAS), despite network impairments, can deliver further bandwidth savings,

full signaling robustness, and a high Call Completion Rate (CCR). In addition to bandwidth savings, this capability enables cost-effective network

topologies based on the optimal location of signaling gateways at a small number of strategic sites.

Cost-Effective Fax, Modem, and Video Services

The highly efficient signal detection and processing techniques of I-Gate 4000 Media Gateways provide voice, fax, modem, and video calls with

unrivaled completion rates and with the exceptional quality, allowing the operator to curtail expenses while capturing billable minutes.

Flexible Interoperation

I-Gate 4000 Media Gateways are built with total openness in mind — ready to interoperate with standards-compliant transmission and switching

network elements. These Gateways are consistent with next-generation network architecture models, offering proven interoperability with

multivendor softswitches based on industry standards/protocols such as MGCP, H.248, and SIGTRAN.

Static Trunking Applications

Despite continuing decreases in bandwidth costs, many international routes and national long-distance networks still have high transmission

prices or limited available transmission bandwidth. For telecom operators carrying voice traffic over costly or bandwidth-limited transmission

links, static trunking systems can provide a distinctive option for realizing substantial savings on bandwidth, equipment, and operations, more

efficient utilization of deployed network resources, and new opportunities for improved competitiveness and increasing profitability.

Applications that can stand to benefit from static trunking include:

•

Transmission of long-distance international and domestic telephony traffic

•

Interconnection of MSC switches in mobile networks

•

Backhaul transmission between MSC switches and Points of Interconnection (POIs) to the PSTN

•

Call center and business process outsourcing

•

Backup protection networks
