Yeastar Linkus Cloud Service for S20 License
The Yeastar Linkus Cloud Service for S20 License enables your S20 PBX to connect securely to the cloud for remote access, simplified softphone configuration, and improved team collaboration. It removes the need for complex firewall and port forwarding setups, providing a more streamlined and secure way for users to access their business phone system from anywhere.
Effortless Remote SIP Connections
Setting up remote offices and phones can never be easier. The Yeastar-supplied PBX domain name (FQDN) helps you quickly establish a private tunnel for remote SIP registrations to your PBX. It’s easy and secure to register your remote IP Phones, branch office PBXs, gateways, and alike SIP endpoints to your central office PBX, as if they were deployed on the intranet.
Rigorous Remote Access Control
Allow remote access only to the permitted SIP endpoints. You have complete control over which IP addresses and Extension accounts can register or connect remotely to the PBX.
Shared Business Resources
Through the remote connection, your remote offices and SIP terminals become parts of the central office PBX system and can share the PBX’s resources.

Small and medium businesses using Yeastar on-premises S-Series PBX
