Yeastar S-Series IP-PBX is Yeastar’s entry level offering in the IP-PBX market. The S-Series has been designed to be easy to install, simple to manage and built to perform. Installation is streamlined with auto-configuration, auto detect and plug and play capabilities.
S-Series models provide either 20 or 50 extensions. Both are of a modular design that come fully licensed out of the box and are SIP native for both lines and extensions.
If legacy analogue or digital lines or analogue extensions are required then additional modules can be installed. SIM cards can also be accommodated to allow calls to be made and received over the mobile network.
The Linkus mobile client is available for Apple iOS and Android to allow you mobile to function as an extension on the phone system.
The Yeastar S-Series IP-PBX offers all the features you would expect in a modern phone system along with a couple that you wouldn’t expect – hot standby, a comprehensive hotel/motel package and a billing application for business who on-bill their time to clients.
Both models support hot standby for critical installations. Two S-Series are installed together and linked. One performs the day to day processing but if it fails then the hot standby takes over. The phones and SIP trunk(s) will re-register and the users may not notice anything has happened. Any legacy connections will have to be manually swapped.
Self provisioning of the phones goes one step further with support of common brands such as Yealink, Snom, Cisco, Grandstream, Polycom and Fanvil. Other brands such as Gigaset cordless can be manually provisioned in seconds.
