Capacity of the platform depends on various factors. The major of them are internet bandwidth and hardware.
For the system to work in most cases enough is one public IP address. The IP address should be alsostatic, using private or dynamic IP addresses for the server is not recommended (notice: this requirement is only for the server side, the clients can use private and/or dynamic IP addresses without any limitations).
The VoipSwitch software can run on up to 5 IP addressesper one server. To each IP can be added all types of listeners i.e. SIP, H323, Callback, Callshop, Voipbox listeners.
Hardware – Recommended are servers based on Intel Xeon processors, example configuration below:
- Dual core or Quad core, in configuration of single or dual CPU
- RAM minimum 2 GB
- HDD 100 GB or more
- A server with a Dual or Quad core CPU and 4GB RAM should be able to handle on average 1000 concurrent calls (proxy mode) in wholesale and retail SIP/H323 calling, similar results have been achieved in real production environment also for Calling cards and Callback.
With higher hardware specification it is possible to increase the load on a single server.
Other method for dealing with higher traffic, recommended also for failover and backup, is to build acluster consisting of two or three servers running on one IP address and dividing the traffic among them.
- VoipSwitch runs on Windows Operating System. The system will work on any edition of Windows starting from Windows 2000 through Windows XP, Windows 2003, Vista and to Windows 2008, however it is recommended to use server edition for example Windows Server 2003 or Windows Server 2008.
For the server can be used Web Edition with minimal users license i.e. no additional user licenses are needed.
