System Requirements for PBXHub Server
To deploy PBXHub Server, you need to know the requirements of hardware, Ethernet port, and operating system.
Important: The private subnet of the server MUST be set to
one of the following subnet options, otherwise the server installation would fail.
- 10.0.0.0/8
- 172.16.0.0/12 (excluding the
172.17.x.xand172.19.x.xIP address ranges) - 192.168.0.0/16
Tip: We provide a server calculator to help you calculate
the required server configurations for the entire deployment of Yeastar P-Series Cloud
PBX. For more information, see Server Calculator.
Hardware requirement
The server used to host the PBXHub should meet the following minimum requirements, as listed in the following table, according to the number of PBXs that will be created in the PBXHub Server.
Each PBXHub Server can provide up to
200
Cloud PBX instances, you can scale up the number of PBXHub
Servers according to the number of Cloud PBXs you need.
Note:
- The CC in the following table means concurrent calls.
- To support more than 100 Cloud PBX instances, the firmware of PBXHub server should be 85.15.0.70 or later.
