By utilizing the Becke IAD100-4S, organizations can preserve their existing investment in analog hardware while migrating to a modern, cost-effective digital infrastructure.

Technical Excellence and Voice Quality
The core mission of the Becke IAD100-4S is to deliver a voice experience that is indistinguishable from a traditional landline. To achieve this, the device is powered by a robust hardware architecture and advanced digital signal processing.
1. Superior Audio Processing
The gateway supports a wide array of industry-standard voice codecs, including G.711A/U, G.723.1, G.729A/B, and iLBC. These codecs ensure that voice data is compressed efficiently for network transmission without sacrificing clarity. To combat the common issues of internet-based calling, the device features:
- G.168 Echo Cancellation: Eliminates feedback and echo for professional-sounding calls.
- Dynamic Jitter Buffer: Automatically adjusts to network instability to prevent voice "stuttering."
- VAD & CNG: Voice Activity Detection and Comfort Noise Generation save bandwidth by only transmitting data when someone is speaking, while keeping the background sound natural.
2. Reliable Fax Support
For many industries, such as law, healthcare, and real estate, physical faxing remains a daily necessity. The Becke IAD100-4S provides rock-solid support for T.38 Fax over IP, allowing fax machines to send documents over the internet with high success rates. It also supports T.30 Pass-through for legacy compatibility.
Intelligent Features and Security
Beyond simple signal conversion, this gateway acts as a sophisticated telephony hub. It brings the advanced features of a digital PBX to your old-fashioned analog handsets.
Comprehensive Call Management
Users can enjoy a full suite of supplementary services, including:
- Call Handling: Support for call waiting, call transfer (blind and attended), and three-way conferencing.
- Caller ID: Compatible with global standards (Bellcore, ETSI, DTMF), ensuring you always see who is calling.
- Flexible Dial Plans: Customizable digit maps allow the gateway to automatically route calls or add prefixes based on your location.
