Remote SIP Service

Connect Everything at Ease

No more risky and complex network settings. Connect your remote IP phones, branch office PBXs, gateways, and similar remote SIP endpoints to your PBX, as easily and securely as if they are deployed on your PBX’s intranet.

Custom PBX Domain Name & Private Tunnel


Get a Yeastar-supplied custom domain name (FQDN) for your PBX and simplify your firewall configuration at both the remote and the PBX location.

The Remote SIP Service provides a private & secure tunnel (secured by Yeastar-managed SBC) for your PBX’s remote SIP access, freeing you from the complex network settings.

Custom SIP Access Control. Better Security


Set your own rules to limit who and which devices can access your PBX remotely through the Remote SIP service (by IP address, extension account, or a combination of both).

Eliminate IT & Configuration Hassles


Overcome troublesome firewalls and PBX port forwarding that are problematic to configure or cannot handle VoIP traffic correctly. The service removes all the IT hassles with inbuilt carrier-grade security. Just enable the service and you are ready to go!

Included in the P-Series PBX Enterprise Plan and above

Remote Access Service

Work Together from Anywhere

Enable private, instant remote connection to your PBX’s web portal and Linkus UC Clients, and let your teams work together from anywhere, with unsacrificed security and productivity.

Uninterrupted business communications


Use Linkus UC Clients on any Internet-connected mobile, browser, or desktop to call, chat, meet, and collaborate from anywhere.

All your PBX’s Unified Communications and Collaboration tools–including calling, messaging, conferencing, call center, contacts, and more–are always at your fingertips with the service.

Easy remote system administration


Leverage the easy-to-access PBX domain name and visit your PBX management portal just like any website. Easily monitor PBX running status, add users, change settings, and more remotely as if you were in the office.

Remote access control on 4 dimensions


Only allow access to the resources required, NOT the entire network. Separate remote access permissions are supported on four dimensions: Linkus Access, Web Access, LDAP Access, and API Access. You have complete control over who and what for the remote access.

Better VoIP call quality


Resolve the issue of NAT traversal at the remote location. The Remote Access Service stops the NAT issues from happening to provide a more reliable call environment and improve your call quality.
