Hence, you can imagine the potentiality of this business in the future.

These figures have led many entrepreneurs to join this industry, which has also increased the competition level. In this blog, I have added all relevant information you need to start a mobile VoIP business. Even if you are already running a VoIP business, you will get many additional information in this blog that will help you optimize your existing business.

To become a VoIP Service provider, there are a few infrastructure requirements, apart from creating a sales/marketing infrastructure. Here is a brief guide into the requirements to start a mobile VoIP business:

Step 1: Set up a VoIP Infrastructure (Hardware and Software)


Softswitch with Billing Softswitch is the heart of the VoIP business that controls all transactions, customer records, call routing and invoice billing, report generation in both prepaid and postpaid business models. Softswitch comes in various ratings, primarily based on the concurrent transactions it can handle; for example, a softswitch which can handle 1000 concurrent calls or a softswitch which can handle only 400 concurrent calls.

Apart from concurrent calls, there are other parameters like stability, security, scalability, ease of operations, call connectivity efficiency, call routing mechanisms and other features, which will dictate your choice of softswitch.

Generally, the softswitch comes with inbuilt billing; but if it does not, then you need to invest in separate billing software. However, you should opt for softswitch that has integrated billing functionality in order to ensure hassle-free business transactions.

Bandwidth Optimization & Tunneling Software  This software component is necessary for retail operations, where the internet quality at customer end may not be consistent. And, it also helps service providers offer their services in geographical areas where VoIP calls are blocked by firewalls.

This software, installed on the server side ensures that customers have a smoother quality experience, even if the internet through their 3G/ Wi-Fi connection is not always adequate to support VoIP calls.

Servers & Hosting – The above software is generally installed on enterprise class servers which are hosted in Internet Data Centers (IDC), powered with high quality bandwidth and 24/7 power/air conditioning, while ensuring your services never go down.

You can lease server/bandwidth from IDC’s around the world, the location of the IDC being dependent on your target market and/or quality of service of the IDC.

Step 2: Mobile VoIP Applications

If you opt for the retail VoIP services, then you will need to provide the applications which consumers will use to originate calls. For full-blown retail operations, service providers need to purchase the following software solutions:

Mobile DialerThis is a mobile app, which your customers will download on their mobile phones, in order to make VoIP calls. There are multiple mobile VoIP clients available in the industry, but you should choose the one that offers branding facility, so that your brand will be present and visible to the customers.

Apart from this, the mobile application must be stable, have good voice quality, be able to support bandwidth optimization requirements, and have an easy user interface which allows  your clients to make calls even if they are not a technology geek.

Calling Card – You need to offer calling card facility to retail customers, who want to access VoIP services, but do not have internet availability in their mobile phones.

In order to offer this option to customers, you will need to ensure that your softswitch supports calling cards and has a DID (Direct Inward Dial) or local telephone number configured with it.

Here, DID is a local telephone number that your customers will dial into – thereupon be greeted by an IVR voice system, which will ask them to enter their destination number and the call will be connected.

Call Shop– If you are planning to offer retail services, the call shop feature is a must have for doing business in many countries, wherein customers go to call shops to make cheap long distance calls. This feature allows call shops to manage multiple customer calling infrastructures, from PC/ devices/ mobile phones.

And, can identify and bill the consumer accordingly and easily, while maintaining full control of their operations. REVE Systems’ Softswitch, iTel Switch offers a very advanced call shop feature, which is used by many retail service providers around the world.

Step 3: Own Website, with Credit Card Payment Gateway Support

If you are in the VoIP business, you will get potential customers from all around the world. In order to provide services efficiently to your customers from various geographies, you will need a fully functional website supported with payment options like Credit Cards, PayPal etc. So, customers can pay you seamlessly and use the services.

Step 4: Inter-Connecting with Terminating Carriers


In order to terminate the calls to your customers, both in retail and wholesale business, you will need to interconnect with multiple carriers across the globe who will offer you various termination destinations. It pays to connect with more carriers, so that you have enough choice of rates and destinations, both in terms of cost and quality.

For example, if you are terminating calls to USA, different carriers will offer different rates and quality of services – so you will need to choose these carriers based on their market reputation and quality achieved during your interconnect tests.

These carriers offer destination rates in USD/ min terms; for example, rate to USA could be 0.008 – which means for every 1 min of a single call terminated through their network, they will charge you 0.008 USD.

The termination cost is the single largest variable cost for VoIP operators and hence, you will need to be diligent in choosing carriers and maintaining your accounts with them.

Step 5: Find Customers

Like in other businesses, here you will also need to find customers after you are done establishing the infrastructure and other basic requirements. So, whether you are in the retail or wholesale VoIP services, you will have to find customers and offer competitive rates with good quality of services.

In terms of maintaining quality of services, two important parameters will be your infrastructure- quality and quality of terminating carriers. So, make sure that you choose the right ones.

Step 6: Customer Support

Once you have started acquiring customers and get customer transactions/ calls, you will have to ensure the customer support, so that you can address your customer problems.

If you are serving a global customer base, you will also have to ensure full 24/7 support, in order for your customers to reach you whenever they have any service disruption.
