**Product Overview**
The **Grandstream** **HT881** Analog FXO Gateway is a high-density hybrid VoIP gateway designed to connect multiple analogue PSTN (telephone company) lines to SIP-based IP PBX systems. It provides a scalable solution for businesses that need to integrate traditional analogue telephone circuits into modern VoIP communication networks while maintaining reliability, flexibility, and centralised control.
Featuring 8 FXO ports and 1 FXS port, the **HT881** enables organisations to bring multiple external PSTN lines into a VoIP system and also support a single analogue telephone or fax device locally. It is widely used in business environments requiring multi-line PSTN integration, such as offices, call routing systems, hospitality, and branch deployments.
**Ideal For**
- Medium to large businesses
- Branch office deployments
- Call centres and reception systems
- PSTN to VoIP migration projects
- Multi-line analogue trunk integration
- Hybrid PBX environments
- Hospitality and service industries
**Benefits**
The HT881 allows organisations to connect up to eight analogue telephone lines into a VoIP system, reducing dependency on legacy PBX hardware while enabling SIP-based call routing and unified communications.
Its built-in NAT routing and failover capabilities help maintain communication continuity even in the event of network or SIP server issues, making it suitable for business-critical deployments.
