With this in mind, the transition to SIP should be a key goal for any business still making calls over the PSTN network. Evaluating your current infrastructure and determining whether it is suitable for migration is key. In this post, we’d like to help you determine if you’re ready to successfully implement SIP trunking and offer some advice on which aspects of your existing infrastructure should be considered to make this possible. **Is your infrastructure ready?** As the person responsible for technology in your business, there are steps you need to take to address the new demands that SIP technology will inevitably bring. Below, we’ve highlighted the four key factors you need to consider in the early stages when assessing how and what is needed to make the transition to SIP: 1. **Proper connectivity is key.** It’s true that SIP trunking will save you a significant amount of money, but this cannot be achieved at any cost. If you’re offered the cheapest connectivity option, you’ll struggle to meet the quality and reliability standards you need. The truth is that having the right connectivity must be at the top of your priority list, although you’ve likely already figured out part of this. If you get the connectivity right from the start, you’re well on your way. 1. **Firewall capabilities.** Depending on the telephony provider you choose and the features you use—such as mobility, video conferencing, or unified communications—it will be important to review your existing firewall configuration, as some changes will be necessary. Some common tasks include opening ports that allow voice and video traffic and signaling to flow freely, as well as disabling firewall features such as SIP ALG. A solid understanding of your firewall is often necessary to ensure that all of this is implemented correctly and that your deployment proceeds smoothly while maintaining security. 1. **Capabilities of your existing PBX.** Many older phone systems do not support the standard SIP protocol and require modifications to work with their proprietary servers and phones. It may be worth considering whether it would be more cost-effective to deploy phones that use the standard without modifications and transition to a more modern and flexible solution. Being able to easily integrate a wide variety of devices or applications from the Windows, Android, or Apple stores will allow you to keep pace with technological advancements without having to wait for your proprietary equipment manufacturer to develop the functionality that users demand. 1. **Be sure.** A Session Border Controller (SBC) is a device commonly deployed on SIP networks to manage signaling and audio and video streams. It also resolves any discrepancies between the SIP service provider and your own system to ensure that any differences are ironed out. Every SIP service provider should use an SBC as part of their SIP service delivery, although it’s sometimes worth considering having one in your office as well. **Good news—3CX is offering its SBC for free!** SBC patents are expensive. 3CX offers it free of charge to all 3CX Phone System users. From the 3CX management interface, you can customize each trunk for your providers, ensuring compatibility with them. In addition, if you want to connect multiple branches, 3CX allows you to install its SBC in each office in a simple and secure manner, establishing a tunnel from the remote locations to the central site. **https://www.3cx.com/docs/3cx-tunnel-session-border-controller/#h.pnclxubq0wh9** Looking for **advice** on setting up a SIP trunk for your company?
