According to a report, the global VoIP market is expected to experience a significant growth during the period 2017 – 2024. It is likely to generate US$ 194.5 Billion revenue towards the end of the year 2024. Due to its continuously evolving landscape and so much innovation happening every single day, adoption and usage of VoIP solutions has become imperative for VoIP businesses. In this post, we will be discussing the wholesale VoIP softswitch solution, its key features and how a business should choose the right softswitch.

What is a Wholesale Softswitch Solution?

A few years back, hardware based class 4 switches were dominating the wholesale VoIP business. But with the cloud technology gaining popularity, software switches started replacing its hardware counterparts. Also known as Wholesale Class 4 Softswitch, it is a solution used by service providers who deal in the wholesale VoIP business model. The basic function of a wholesale softswitch is to allow the transfer of traffic between carriers over long distances. This type of softswitch generally handles routing of large call volumes.

Key Features of Wholesale VoIP Softswitch

Some of the key features supported by a wholesale softswitch are as mentioned below:

Integrated Billing system

A wholesale softswitch without an integrated billing system can cause trouble and mess. Using a separate billing software may arise lots of issues like incompatibility, improper functionality, etc. A wholesale softswitch should have features like real-time billing and multi-currency support.

Efficient Routing

A softswitch capable of implementing different types of routing can generate maximum profits. Least Cost routing (LCR) is quite important as it helps the switch to detect the outbound line that costs the least. Further, Percentage Routing ensures that the softswitch will transmit the call through a route that has the highest percentage and in case it is not available, then it chooses the next highest percentage.

Secure Functioning

SIP Topology hiding is an advantageous feature from a security point of view. It is easy for hackers to get into any SIP network if they get access to IP address data sent into the SIP traffic. Topology hiding prevents outsiders i.e. hackers or attackers from stealing the IP address data and thus secures the network.


Generating reports is one key feature that helps in tracking performance of the business and making decisions for its growth. A softswitch that can provide reports for calls including incoming, outgoing, active, and unauthorized, etc. can be very useful for the business. Reports for traffic volume, payment, sales and revenue can also be looked for.


The softswitch must be able to support the increasing demand for the number of concurrent calls and call per second support. A softswitch that is not able to fulfil your increasing business requirements can become a roadblock to business’s growth.
