Elastic SIP Trunking explained

In this section, we'll explore what you need to know when comparing two elastic SIP Trunking providers, such as Telnyx and Twilio. The four factors you’ll want to consider are whether the provider offers a private network, whether or not they are a carrier, what type of configuration and monitoring interfaces they offer, and how they port numbers.

Private network
Carrier status
Configuration and monitoring interfaces
Number porting

Private network

There are two types of networks: public and private. A private IP network, custom-built for communication purposes, represents a huge shift in telephony. Private networks offer benefits you won’t find using a public network.

Here are three reasons you should choose a private network:

1. Superior quality for real-time communication: A private IP network is constructed specifically to handle real-time communications. Unlike the public internet, which wasn't primarily designed for such tasks, private networks are optimized to minimize packet loss and latency issues. Private networks allow users to enjoy high-quality, crystal-clear calls without any interruptions.

2. Enhanced security measures: The public internet is vulnerable to various security threats due to its open nature. Conversely, a private network poses a significant barrier to potential cyber attackers, making it much harder to compromise the communications happening on it. Some private network providers offer the option for customers to encrypt their SIP signaling and media streaming, protecting their data further.

3. Robust reliability and uptime: The public internet does not guarantee uptime, which can lead to service interruptions. On the other hand, private multi-cloud networks incorporate built-in redundancy, which results in a high level of service reliability not found on the public internet.

The core value of a private IP network lies in its ability to provide high-quality call experiences, exceptional security, and dependable reliability. These attributes make it an attractive and necessary feature for any customer who values communication integrity and consistency.

Carrier status

Carrier status plays a crucial role in your company's ability to expand voice connectivity around the globe. With a licensed carrier, you can scale your operations more fluidly, avoiding potential roadblocks that could occur due to dependencies on relationships with local carriers. Working with a provider who is also a carrier means your business can grow without the connectivity-related complications that could arise from relying on numerous third-party local carriers.

Configuration and monitoring

User-friendly interfaces for configuration and monitoring are essential for any communication service provider. The ability to automate these processes can significantly improve the efficiency of your operations. With API functionality, you manage configuration and monitoring more effectively, as well as automate various communication processes.

Automating processes—such as number porting, capacity scaling, and reporting and monitoring—enables you to manage your communication processes more efficiently, offering greater control and flexibility to your operations.

Number porting

The standard process for number porting often involves a cycle of multiple emails, leading to wasted time and frequently rejected port requests. Thus, a service provider that offers a solution to streamline this process is of immense value. Consider an option that transforms number porting into a smooth, time-efficient task, in contrast to more traditional, time-consuming methods.

A seamless porting process saves time and effort and eliminates unnecessary delays and resource wastage. By choosing a service provider with a streamlined number porting process, you're essentially investing in improved business efficiency and a smoother operational experience.

Which provider offers the best SIP Trunking solution?

When choosing a SIP trunking provider, it’s important to consider the four factors outlined above. Although both Telnyx and Twilio offer some of the same functionalities, there are some important differences to consider.

Twilio relies on the public internet. Telnyx uses a private network, which provides better call quality, security, and reliability. Telnyx is a licensed carrier in multiple countries, whereas Twilio depends on relationships with local carriers, which may result in additional challenges when scaling.

Both providers offer intuitive user interfaces for configuration and monitoring. However, Telnyx provides additional functionality through its API, enabling you to automate communication processes—including number porting, capacity scaling, reporting, and monitoring—more easily.

Telnyx's FastPort® technology streamlines the number porting process, saving you time and effort. Twilio's manual porting process is more time-consuming and frustrating.

When customers are dealing with a local business, they expect to see a local number. Geomatch will automatically send messages from a number that matches the local area code of the recipient from within your pool of numbers. Local numbers allow you to establish trust more quickly and better engage users with a more tailored, local experience.

Metrics and reporting

Real-time metrics serve as an essential tool for gauging business performance. The ability to access granular delivery reports, monitor the status of your numbers, and comprehend customer interaction with your messages through click-through-rate tracking are fundamental components of effective messaging campaigns.

These detailed insights not only allow businesses to fine-tune their strategies in real time but also provide them with a comprehensive understanding of their campaign effectiveness.
