Types of SIP Service Providers

There are different types of SIP service providers you can choose based on easy use and management or control over your system, such as:

1. Hosted SIP (PBX) Providers

This type of SIP service is popular with businesses of all sizes. In these service providers, the hosting company provides all the services rather than the organization that uses them. Therefore, the host does the work of servicing, upgrading when necessary, and preparing for data loss.

Nextiva, RingCentral, and 8×8 are some of the hosted SIP service providers known for providing exemplary service in terms of call quality and other services that make the installation process easier.

2. On-premises SIP providers

Using the PBX system doesn’t require a substantial hardware investment or specialized personnel. However, On-premises SIP providers provide SIP trunk features by connecting to a firm’s existing PBX system.

This method enables companies to process call routing and other features more effectively than hosted solutions. In this category, businesses may also take advantage of what traditional PBX vendors such as Mitel and Avaya offer, such as SIP trunking services based on their existing PBX infrastructure.

3. Hybrid SIP Providers

Hybrid SIP service is a useful option for companies looking to take advantage of cloud-based features while maintaining control over their current PBX system.

By converting to this service, you can enjoy core functionalities, such as call routing and management, similar to a hosted solution. You can also control and customize your call features by integrating them with your existing PBX hardware.

What factors should be considered when choosing the right SIP service provider?

You can use SIP services to improve your communication capabilities and save money. However, before turning to an SIP service user, there are some factors you need to take into consideration, which are:

  • Voice quality: Ensure your calls are clear and work well with SIP trunking. To emphasize quality in their services, choose reliable SIP trunk providers. Kindly avoid service providers using the least-cost routing technique (LCR).
  • Coverage: Choose a provider that grows with your VoIP system without the hassle of dealing with multiple local carriers. Acquiring a company that offers numbers to call outside the country can be essential to your search for a provider.
  • Reliability: Effective SIP trunking requires reliable call connections. If calls frequently fail or don’t go through, the benefits of SIP trunking diminish. When choosing a provider, look for those with backup systems and multiple connections to different carriers in various locations.
  • Cost: The prices and billing structures differ among the SIP trunk providers. When looking for a provider, it is essential to consider the price that will yield maximum savings for your business based on the precise level of service that you need.
  • Security: You must prioritize security when choosing an SIP service. Therefore, when you contract an SIP trunk provider, you need to protect your network from unauthorized access or call interception.


You must select the right SIP service provider to get dependable, reliable, and cost-effective communication solutions for your business. In India, there are different SIP service providers that offer different features, scaling capabilities, and consistently good calling quality that you might need for your precise business needs. 

Regardless of your business size, you can find an SIP service that best fits your business requirements. To choose the best options, such as RingCentral, FreJun, Nextiva, Vonage, etc., you must consider factors such as voice quality, coverage, reliability, cost, security, etc. Therefore, evaluate every factor according to your needs and then select the best option.
