1 Assess your current needs

Before you switch to SIP trunking, you need to evaluate your current voice and data usage, infrastructure, and budget. How many concurrent calls do you make or receive? How much bandwidth do you have and need? What kind of features and services do you require? How much do you spend on your phone bills and maintenance? These questions will help you determine the optimal size, capacity, and configuration of your SIP trunking solution, as well as the potential savings and benefits you can expect.

Not mentioned above is Calls Per Second (CPS) — the rate at which you need to attempt new calls. If you’re sending out Airline flight cancellation phone calls, or Government military activation notifications, you will need a higher-than-typical calling rate. Some SIP trunking providers have no experience with this legitimate “Dialer” traffic. Also, be aware of anti-spam, anti-robocalling requirements. Your existing provider may be providing this for you (e.g., STIR/SHAKEN, or verified caller ID). Your SIP trunking provider may expect you to provide your own certificate proving you have the rights to call from your numbers.

2 Compare different providers

Not all SIP trunking providers are created equal. They may vary in terms of pricing, quality, reliability, scalability, security, and customer support. You need to compare different providers based on these criteria and choose the one that best suits your needs and budget. You can also look for reviews, testimonials, and references from other customers to get a sense of their experience and satisfaction. Don't be afraid to negotiate and ask for discounts or incentives if possible.

SIP trunking providers vary WIDELY. Two main distinctions: those that connect to the major other regional carriers via SIP, and those that connect primarily via TDM and SS7/C7. The benchmark is how the SIP trunking provider connects to the major cellular providers. In the USA that’s AT&T, Verizon and T-Mobile. SIP based providers may cost more, it can increase audio quality and reduce the “spam likely” false labeling. In the US, Canada and France, SIP end-to-end can make a massive difference in call completion and delivery rates. And when brand trust information is delivered via STIR/SHAKEN you’ll really want to have a provider who can deliver! TDM providers are more common, cheaper. Know the limitations.

3 Optimize your network

SIP trunking relies on your internet connection to deliver high-quality voice and data services. Therefore, you need to optimize your network to ensure sufficient bandwidth, speed, and performance. You may need to upgrade your router, firewall, switch, or other network devices to support SIP trunking. You may also need to configure your network settings to prioritize voice traffic over data traffic and avoid congestion, latency, or jitter. You can use tools like speed tests, ping tests, and traceroute to monitor your network performance and troubleshoot any issues.

The wording above is OK, but very often small businesses get lucky with ordinary Internet connections. Nevertheless, it’s very hard to test - because you need calls to work right even when your Internet link is busy. You need maximum calling at your busiest time of day. You can’t test that outside business hours! SD-WAN can be a great option, especially those with built in Packet Loss Concealment (such as the VMWare SD-WAN). With multiple Internet links these products can provide solid network links even when one is saturated or otherwise experiencing packet loss.

4 Secure your system

SIP trunking exposes your voice and data networks to the internet, which means you need to protect them from cyberattacks, fraud, or unauthorized access. You need to implement security measures such as encryption, authentication, firewall, VPN, or SBC to safeguard your SIP trunking system. You also need to follow best practices such as updating your software, changing your passwords, and monitoring your call logs to prevent any breaches or misuse. You can also consult your provider for any security recommendations or assistance.

5 Monitor and adjust

SIP trunking is a flexible and scalable technology that allows you to adapt to changing business needs and demands. You need to monitor and adjust your SIP trunking solution regularly to ensure optimal performance and efficiency. You can use analytics and reports to track your voice and data usage, quality, costs, and benefits. You can also use feedback and surveys to measure your customer satisfaction and loyalty. Based on these data, you can adjust your SIP trunking settings, features, or plans to meet your current and future goals.
