Server Calculator

We provides a server calculator for you to calculate the required server configurations for the entire deployment of Yeastar P-Series Cloud PBX. The requirements of YCM Server, SBC Server, and SBC Proxy Server are fixed while that of the PBXHub server changes according to the capacity you specified. In future use, you need to keep monitoring the PBXHub Server, and expand the server capacity accordingly if you need more Cloud PBXs.

Specify the desired capacities in the following fields, then click "Calculate". The calculator will provide recommended values for the servers.

Note: The calculator provides server requirements of up to 100 P-Series Cloud PBXs. If you need to deploy more than 100 P-Series Cloud PBXs, contact Yeastar.

    Network Configuration Requirements:

    a. All the servers use single Ethernet port.

    b. For the YCM Server, SBC Server, and SBC Proxy Server, you should configure an NAT gateway to implement inbound and outbound internet connectivity. Make sure that the inbound and outbound IP addresses of a server are the same.

    c. For PBXHub server that only has private IP address, you should configure an NAT gateway for the server to only initiate one-way connection to the Internet, but not need to receive inbound connections initiated from the Internet.

    d. Make sure that the YCM Serer, SBC Server, SBC Proxy Server, and PBXHub Server can communicate with each other in both private network and the public Internet.

    e. Private IP address can NOT use 172.xxx.xxx.xxx.
