As a professional integrated SBC, VoIP Gateway, and FXS Gateway solution, Synway next-generation Hybrid VoIP Gateway and SBC perfectly bridges traditional TDM/PSTN networks and modern IP multimedia communication systems. Designed to eliminate cross-network interoperability barriers, strengthen communication boundary security, and stabilize voice and media transmission, this all-in-one device serves as the core communication access gateway for enterprises, contact centers, BPO institutions, and communication service providers. Supporting up to 2000 concurrent SIP sessions and equipped with dedicated DSP media processing capabilities, it integrates the functional advantages of professional SBC, high-performance VoIP Gateway, and practical FXS Gateway, realizing one-device multi-scenario deployment and effectively reducing enterprise communication construction and operation costs.
Validated by over 500 global service providers and enterprise users, our Hybrid VoIP Gateway and SBC features excellent protocol compatibility, telecom-grade reliability, and flexible service expansion. It comprehensively solves common industry pain points including SIP protocol incompatibility, NAT traversal failure, poor voice quality, network attack intrusion, and single-line service interruption, becoming a reliable core facility for enterprise unified communication and VoIP trunk access.
Core Product Advantages
1. All-in-One Integration: SBC + VoIP Gateway + FXS Gateway + Hybrid Access
Different from single-functional network communication devices, Synway integrated equipment innovatively combines professional SBC border control, standard VoIP Gateway media conversion, and practical FXS Gateway terminal access capabilities, forming a complete Hybrid VoIP Gateway and SBC integrated solution. It supports E1/T1 PSTN traditional circuit access, FXS analog terminal access, and SIP IP network multi-mode interconnection, realizing seamless communication docking between analog phones, traditional PBX, PSTN public network, and cloud SIP trunk platforms. The hybrid architecture supports automatic failover from IP network to TDM/PSTN line, ensuring uninterrupted outbound call services and perfectly adapting to the gradual migration scenario of traditional communication to full IP communication.
2. Standardized SIP Normalization & Full Media Transcoding
Built on mature B2BUA architecture, the professional SBC module achieves full normalization of heterogeneous SIP protocols, perfectly adapting to different brands of IP-PBX, UC systems, and operator SIP trunks. It supports flexible SIP header modification, inbound and outbound number manipulation, and multi-protocol conversion of UDP/TCP/TLS and IPv4/IPv6. Equipped with independent DSP hardware transcoding resources, the device eliminates the need for additional transcoding hardware, supporting mainstream encoding formats such as G.711, G.723.1, G.729, AMR-NB, SILK, and Opus. Combined with the media processing capability of the VoIP Gateway module, it solves industry problems such as unmatched encoding formats, failed fax transmission, and DTMF recognition errors, greatly improving call completion rate and communication stability.
3. Full-Dimensional Boundary Security Protection
As the security gateway for enterprise external VoIP communication, the SBC module provides line-rate DoS/DDoS attack defense, bandwidth limiting, and dynamic blacklist interception, effectively resisting network intrusion, service theft, and call fraud. It supports TLS/IPSec signal encryption and SRTP media encryption, matched with SIP digest authentication, HTTPS/SSH secure management access, and network topology hiding technology. While ensuring open access of VoIP Gateway and FXS Gateway services, it fully isolates internal communication equipment from external public networks, comprehensively guarantees enterprise communication data privacy and service security, and avoids economic losses caused by malicious attacks and illegal calls.
4. Telecom-Grade High Reliability & Service Survivability
The Hybrid VoIP Gateway and SBC solution supports 1+1 active/standby HA redundant deployment, realizing seamless failover without interrupting ongoing calls. It has independent local survivability capability: when the WAN IP network fails, the system can still maintain internal local calls; when the IP trunk is abnormal, it automatically switches to the PSTN line accessed by the VoIP Gateway for outbound calls, and supports E911 emergency call priority processing. Built-in G.168 echo cancellation, dynamic jitter buffer, silence suppression, and RTP redundancy mechanisms effectively optimize voice quality fluctuations caused by network jitter and packet loss, ensuring stable and clear voice communication for long-term 7×24-hour operation of key business systems such as contact centers and emergency communications.
5. Flexible Scalability & Fine-Grained Traffic Management
The product supports flexible session capacity expansion from 5 to 2000 concurrent SIP sessions, meeting the communication scale requirements of small and medium-sized enterprises to large enterprises and service providers. It has powerful call admission control and resource scheduling capabilities, which can limit the number and registration rate of concurrent sessions in inbound and outbound directions. It supports multi-dimensional intelligent routing such as SIP trunk matching, DID number segment, codec priority, and bandwidth monitoring, and integrates load balancing, least-cost routing, and call forking functions. Cooperating with the access capability of the FXS Gateway, it realizes unified management of analog terminals and IP terminals, standardizes enterprise communication traffic, and optimizes overall business operation efficiency.
Typical Application Scenarios
