Developing practical solutions based on this demand…

Pain Points (Public)

Distributed branch offices deploying heterogeneous network hardware—such as 5G cellular routers, dual-WAN edge appliances, and on-premises IP PBX systems—frequently experience broken SIP registration, one-way audio, and unstable site-to-site VPN tunnels due to carrier-grade NAT (CGNAT) and conflicting routing or ALG policies.

Suggested Approach (Public)

Audit multi-vendor gateway routing and deploy a cloud VPS running WireGuard or IPsec as an intermediate relay for NAT traversal, while disabling problematic SIP ALG inspection and tuning keepalive intervals and port forwarding on the local PBX.

How to position

Target distributed businesses running multi-vendor hardware (specifically DrayTek routers, Cudy 5G gateways, and Yeastar IP-PBXs) by positioning a pre-configured WireGuard hub on a cloud VPS to bypass carrier-grade NAT (CGNAT) and avoid brittle SIP ALG setups.

What to build first

1. Build an automated cloud VPS deployment script that spins up a WireGuard hub with standardized endpoint configs for Yeastar PBX and DrayTek/Cudy network appliances.
