In order to find out the SIP softswitch capacity requirements for your VoIP business, there are multiple factors that are to be taken into consideration. Some of the important ones are mentioned below:

• Subscriber Base
• Volume of Calls
• Number of Registrations

Subscriber Base

This is very important factor before you decide on the softswitch requirements. If you already have an existing customer base then it becomes easy for you to determine what kind of softswitch is required for your business. Otherwise, you have to do a market analysis for the region you want to launch the VoIP business. This is to ensure that you get the right softswitch with necessary configuration for your VoIP business. Also, it avoids unwanted expenditure on things you don’t require your softswitch to perform. So, the first thing before selecting the VoIP softswitch for your VoIP business is to determine the subscriber base that you want to engage with.

Volume of Calls

After determining the subscriber base, it is essential to figure out how much volume of calls are required for seamless operation of your VoIP business. For instance, if you have 20,000 subscribers and at any moment of time you see there is a need for 2000 active calls then your softswitch should offer 2000 concurrent calls. That means, a softswitch with 2000 concurrent call capacity can process 2000 active calls at any moment of time. Beyond that limit, you might experience call drops as your softswitch is built to process only 2000 concurrent calls. So, it is very important to determine the volume of calls (concurrent calls & calls per second) that you would like to process through softswitch at any given instance. In case, if you are not able to figure that out then it’s highly recommended that you consult a VoIP solution provider who does the necessary analysis for your VoIP business.

Number of Registrations

This is another important factor that you should consider during the selection of any softswitch for your VoIP business. A softswitch that allows more number of registrations is always a good choice as it doesn’t affect your business performance. However, when you go for a softswitch with limited registrations then there is a high possibility that it might affect the switch performance as additional registrations would consume extra cache and storage on the server resulting in unexpected outcomes. So, the number of registrations will solely depend upon your subscriber base and it always greater than the volume of calls required for your VoIP business.
