- Business Continuity: Ensures communication even if internet or SIP trunks fail
- Scalable Setup: Available in multiple port options (4, 8, 16, etc.) to match business needs
- Improved Call Handling: Supports features like caller ID, call routing, failover, hotlines, and more
- Cost-Effective Migration: Allows gradual shift from analog to IP without major infrastructure changes
Ideal Use Cases

- Offices needing backup PSTN lines for reliability
- Businesses connecting remote branches to the main IP PBX
- Companies wanting to retain existing analog trunks while upgrading to VoIP
