Dialogic I-Gate 4000 Media Gateway
The I-Gate 4000 family comprises two hardware variants: the I-Gate 4000 PRO and the I-Gate 4000 EDGE. Both operate on an open, standards-based platform designed for class 4 switching environments and IP transformation workflows. The gateways deliver toll-quality voice compression, IP-to-IP transcoding, and support for modern voice services, enabling service providers to reduce operational costs while maintaining network availability.
Key platform attributes include:
- HD Voice support for next-generation audio services
- IP-to-IP transcoding without quality degradation
- Bandwidth optimization delivering up to 93% savings (up to 16:1 compression ratio) for inter-gateway applications
- High call completion rates for voice, fax, modem, and video traffic
- Up to six 9s availability (99.99995%)
- Compatibility with terrestrial, radiolink, and satellite transmission media
The I-Gate 4000 series is engineered to replace end-of-life media gateways from legacy vendors (including Cisco) while preserving existing infrastructure investments.

Signaling and Transport Support
The I-Gate 4000 provides robust transport for circuit-switched signaling protocols, maintaining full signaling robustness and high call completion rates (CCR) even under network impairment conditions.
Supported signaling standards include:
- SS7 (M3UA): Signaling System No. 7 over MTP3 User Adaptation
- PRI: Primary Rate Interface
- QSIG: Private network-to-network signaling
- CAS: Channel-Associated Signaling
Signaling gateways can be strategically consolidated at a minimal number of network nodes, enabling cost-effective topology design without sacrificing reliability or bandwidth efficiency.
System Integration and Architecture
The I-Gate 4000 integrates into Dialogic’s IMS transformation portfolio alongside the ControlSwitch System softswitch and BorderNet Session Border Controllers. This stack provides a complete solution for network modernization, capacity expansion, and legacy hardware retirement.
Deployment patterns typically include:
- Replace legacy media gateways with I-Gate 4000 PRO/EDGE units at existing POP locations.
- Deploy BorderNet SBCs at network edges for session management and security.
- Route signaling and media through ControlSwitch System softswitch for call control.
- Validate capacity and performance using Dialogic Analytics for real-time monitoring.
Operational validation is documented in partner case studies, such as Teleena’s deployment, which combined BorderNet 4000 SBCs with I-Gate 4000 PRO gateways to replace legacy session border controller technology and expand Cisco gateway infrastructure.
